	11 Feb 2022	Solving Bird Mysteries with Forensic Ornithology	00:49:08
This episode is all about forensic ornithology. This is a field where specialists use scientific techniques to identify bird species from trace evidence. Evidence like maybe a bit of feather, a bone fragment, or a smear of blood. Forensic ornithology is used to solve intriguing wildlife crimes like smuggling and illegal hunting. But it’s also helpful in other situations that don’t involve criminal activity. We’ll get into that side of things too. Like a murder mystery novel, today’s subject is, pretty much by definition, morbid. I’ll be talking a lot about dead birds. Blood and guts and all that. I prefer my birds very much alive, thank you, and I’m sure you do too. But, despite the gore, I think you’ll find that forensic ornithology is a fascinating topic. It’s worth learning about, to better appreciate the ways people fight to protect birds. ~~ Leave me a review using Podchaser ~~ Links of Interest Chuparosa article The Remarkable Life of Roxie Laybourne US Fish and Wildlife Forensics Lab Forensic Ornithologist: Pepper Trail Forensic Ornithologist: Ariel M.

	18 Feb 2022	Wallace's Line: Where Two Bird Worlds Collide	00:19:21
This episode—which is Number 46—is about a special place in the Malay Archipelago where two bird worlds collide. This region lies between Southeast Asia and Australia, between the Indian and Pacific oceans. And it’s crowded with about 25,000 islands, of all sizes. Specifically, we’ll be looking at a geographic feature called Wallace’s Line. More generally, today’s episode will touch on the topic of biogeography. ~~ Leave me a review using Podchaser ~~ Link to this episode on the Science of Birds website Support the show
	10 Mar 2022	Gulls, Terns, and Skimmers (Family: Laridae)	00:42:02
This is Episode 47. It’s all about birds in the family Laridae. This is an ancient evolutionary lineage that originated over 70 million years ago, when the world was still ruled by dinosaurs. Besides gulls and terns, the family Laridae also includes the skimmers and the noddies. ~~ Leave me a review using Podchaser ~~ Links of Interest Shoplifting gull stealing Doritos.

	25 Mar 2022	The Pecking Order: Dominance Hierarchies in Birds	00:27:01
This episode—which is Number 48—is about the “Pecking Order” in birds. Or, to use the more technical term, dominance hierarchy. Our focus will be on dominance hierarchies that we see among birds within a single species. White-crowned Sparrows beating up on other White-crowned Sparrows, for example, as opposed to White-crowned Sparrows beating up on another species, like Lincoln’s Sparrow. The latter would be an example of interspecies dominance. But today, we’re talking about intraspecies dominance. Meaning within species. ~~ Leave me a review using Podchaser ~~ Links of Interest Pukeko video Pukeko fighting video Link to this episode on the Science of Birds website Support the show
	06 Apr 2022	Nests: Types, Construction, and Challenges	00:52:02
This episode—which is Number 49—is all about bird nests. There are tons of fun facts fun facts here, since nests are one of the more impressive aspects of bird behavior and breeding biology. We’ll go over the functions of nests, the challenges that nesting birds face, nest site selection, the many types of nests, and nest construction. That’s a lot to cover, but I’ll try to keep this at more of an overview level. This is sort of Bird Nests 101. ~~ Leave me a review using Podchaser ~~ Links of Interest Why a Hawk Is a Hummingbird’s Best Friend Time Lapse Video of Blue Tit Building a Nest BBC Video of Baya Weaver Nest Construction Link to this episode on the Science of Birds website Support the show
	19 Apr 2022	Female Birdsong	00:21:51
This episode—which is Number 50— is all about Female Birdsong. Songs are one of the things we love most about birds. They define the soundscapes of the natural world. Even though humans have been surrounded by singing birds for millions of years, we still have some misconceptions about birdsong. Today’s episode is about a misconception of sex differences in birds… Of who sings and who doesn’t. ~~ Leave me a review using Podchaser ~~ Links of Interest The Forgotten Female: How a Generation of Women Scientists Changed Our View of Evolution Female Bird Song Project Video of Superb Fairy Wren female Singing Singing female Cerulean Warblers [Video] Link to this episode on the Science of Birds website Support the show
	06 May 2022	The Northern Cardinal	00:32:43
This is Episode 51. Our bird of interest today is the Northern Cardinal, Cardinalis cardinalis. This species is widespread across the eastern and southern US. It’s so well-known and loved that it’s the state bird for 7 states—more than any other species. Northern Cardinals are among the most abundant birds in North America. They’re familiar denizens of backyards that visit feeders all year long. So it shouldn’t be surprising to hear that ornithologists have done a lot of research on this abundant and conspicuous species. ~~ Leave me a review using Podchaser ~~ Link to this episode on the Science of Birds website Support the show
	26 May 2022	Giant Birds: Go Big or Go Home	00:28:47
This is Episode 52. Today, we’re talking about bird species that are way, way bigger than your average chickadee or finch. Our focus will be on evolutionary lineages that spawned some very large bird species. Species whose ancestors had been much smaller, millions of years earlier. We’ll look at a bunch of interesting giant birds throughout history. Then we’ll talk about some scientific explanations for why these critters got so big in the first place. ~~ Leave me a review using Podchaser ~~ Links of Interest The Time Terror Birds Invaded [Video] Takahe - Return to the Wild [Video] Island Gigantism Link to this episode on the Science of Birds website Support the show
	12 Jun 2022	Avian Flu	00:34:26
This episode—which is Number 53—is all about Avian Influenza. Or colloquially what we call the Avian Flu or Bird Flu. Depending on where you live, you might have noticed news headlines in recent months about the frightening spread of Avian Flu among both domestic and wild birds. I thought you might have some questions about this emerging disease, and so here we are with an entire podcast episode on the subject. ~~ Leave me a review using Podchaser ~~ Links of Interest Current U.S. Bird Flu Situation in Humans Link to this episode on the Science of Birds website Support the show
	24 Jun 2022	Eggs: Incredible and Commendable	00:56:30
This episode—which is Number 54—is all about bird eggs. This is an important topic. Eggs are a fundamental aspect of bird biology. Recently, in Episode 49 of the podcast, I covered the topic of nests. So it seems like a logical next step for us to get the lowdown on eggs. Oology is the science of studying bird eggs. So today, we are all honorary oologists. We’re egg-heads on a mission to better understand how baby birds come into the world. ~~ Leave me a review using Podchaser ~~ Book Recommendations The Most Perfect Thing: Inside (and Outside) a Bird’s Egg [affiliate link] Links of Interest How are Eggs Made (BBC/Attenborough clip) [VIDEO] Chicken embryo development animation [VIDEO] Bird Eggs Warn Each Other About Danger [VIDEO] Link to this episode on the Science of Birds website Support the show
	08 Jul 2022	Flamingos	00:45:59
This is Episode 55. It’s all about birds in the avian family Phoenicopteridae. These are the flamingos. No doubt you already know a fun fact or two about flamingos. These birds are crowd pleasers that get a lot of attention. But today we’re doing a deep dive into their biology. I’m hoping that along the way, you’ll pick up some new flamingo trivia that you can impress your friends with. ~~ Leave me a review using Podchaser ~~ Links of Interest Underwater Flamingo Feeding [VIDEO] Flamingo courtship dance [VIDEO] Over a Million Flamingos \| The Great Rift: Africa's Wild Heart [VIDEO] Link to this episode on the Science of Birds website Support the show
	21 Jul 2022	How Bird Feathers Get Their Colors	00:44:46
This episode—which is Number 56— is all about the colors of birds. The diversity of color in bird plumages is one of the things we love most about these animals. But bird plumages are impressive not only when they display vibrant colors plucked from the rainbow. Thousands of species aren’t what we’d call colorful, but they do have gorgeous, intricately patterned feathers in combinations of black, brown, and white. Today, we’re looking at how feathers get their colors, from white to subtle earth tones to scintillating displays of wild iridescence. ~~ Leave me a review using Podchaser ~~ Links of Interest Sponsor Link: Sign up through wren.co/birds to make a difference in the climate crisis, and Wren will plant 10 extra trees in your name!

	07 Aug 2022	Flocking Behavior in Birds	00:33:55
This episode—which is Number 57— is all about the flocking behavior of birds. Birds of many species spend at least part of their yearly cycle hanging out in groups. This could be just a handful of individuals or it could be a gathering of millions of birds. Today, we’ll look at some explanations for why—as the saying goes—birds of a feather flock together. What benefits do birds get from forming groups like this? We’ll also look at how flocks work. As in, their mechanics. For example, how do birds communicate and coordinate their movements in a flock? ~~ Leave me a review using Podchaser ~~ Links of Interest Starling Murmuration [VIDEO] Boids algorithm demonstration Link to this episode on the Science of Birds website Bird Conservancy of the Rockies [Learn More] Bird Merch — Get yourself some bird shirts!

Today’s episode—which is Episode 58—is all about birds in the family Troglodytidae. These are the wrens. Wrens are small, perky songbirds, most of which are some shade of brown. All the species in this family of birds are found in the New World—In North, Central, and South America. All of them, that is, except for one species found in the Old World. In this episode, we'll cover many aspects of wren biology: their behavior, voices, diversity, evolution, conservation, and breeding. ~~ Leave me a review using Podchaser ~~ Link to this episode on the Science of Birds website Bird Conservancy of the Rockies [Learn More] Bird Merch — Get yourself some bird shirts!

	15 Sep 2022	Feeding Wild Birds: Pros and Cons	00:51:03
This episode—which is Number 60—is about Feeding Wild Birds. As in, humans providing supplemental food for wild birds. This typically involves a contraption called a birdfeeder. When you or I hang up a birdfeeder, we’re feeding wild birds intentionally. This intentional feeding is what today’s episode is about. Millions and millions of people all around the world feed wild birds intentionally. At such a massive scale, you have to imagine this would affect birds significantly, and in many ways. And it absolutely does. Which brings us to the big question: should we or shouldn’t we feed wild birds? This is still being debated. By scientists, conservation organizations, and bird lovers everywhere. Today, I’ll do my best to give you objective, scientific information about feeding birds. We’ll look at the pros and cons. Then, we’ll see if there’s any sort of conclusion we can come to at the end of the episode. ~~ Leave me a review using Podchaser ~~ Links of Interest Analysis: Do Bird Feeders Help Or Hurt Birds?

	29 Sep 2022	Ostriches	00:41:42
This is Episode 61, and it’s all about Ostriches. These are the birds in the avian family Struthionidae. Ostriches are among the most recognizable and charismatic birds. No living bird is bigger than an ostrich. If you’ve ever seen one up close, you know how impressive these giants can be. They’re amazing. So I’m excited to dig into their biology with you today. You probably know a thing or two about Ostriches already, but let’s see if we can get a deeper understanding of them. We’ll look at their basic traits, their distribution, habitat, diet, and more. ~~ Leave me a review using Podchaser ~~ Links of Interest Cyclists chased by an ostrich [VIDEO] Link to this episode on the Science of Birds website Bird Conservancy of the Rockies [Learn More] Bird Merch — Get yourself some bird shirts!

	13 Oct 2022	Biogeographic Realms and Their Unique Birds	00:38:08
This episode—which is Number 62—is all about the major geographic divisions among birds across the planet. Why are bowerbirds found only in Australia and on the islands of New Guinea? Why are the birds you see in India so different from those in China? Does North America have any unique, endemic bird families? Questions like these fall within the domain of biogeography. Biogeography is the study of where living things are found and why they’re found there—both in the present and the past. Today, we’ll be sketching out the big picture of what types of birds are found where across the world map. By learning the basics of bird biogeography, you can get a deeper appreciation for the uniqueness of bird communities in different parts of the world. ~~ Leave me a review using Podchaser ~~ Links of Interest What Are The 7 Realms of Biogeography?

	07 Nov 2022	The Common Raven	00:53:19
This episode—which is Number 63—is about the Common Raven, Corvus corax. This species is also known as the Northern Raven. Few bird species in the world are as geographically widespread as the Common Raven. And few are as familiar and iconic. This is a really amazing bird. Ornithologists and other scientists have studied ravens extensively, so we know quite a lot about this species. Today, we’ll look at the basic traits of the Common Raven as well as its behavior, habitats, diet, reproduction, and more.

	22 Nov 2022	Bird Habitat: Temperate Grasslands and Prairies	00:43:04
This episode—which is Number 64—is all about the importance of temperate grasslands as habitat for birds. When we say “temperate grasslands,” we mean those generally occurring in the middle latitudes. Temperate grasslands exist in several parts of the world. Some of them cover vast areas. Here in North America, we have the Great Plains as a “great” example. The steppes of Mongolia and the Pampas of South America are similarly vast temperate grasslands. Many, many bird species around the world depend on such grasslands for food and breeding habitat. Among them are raptors, sparrows, blackbirds, larks, pipits, a bunch of South American species in the ovenbird family, Furnariidae… and the list goes on. But, unfortunately, temperate grasslands are also among the most threatened ecosystems on the planet. Many of the bird species that call them home are, not surprisingly, also in trouble. Today, we’re going to dive into what makes temperate grasslands special, and why they’re so important to birds. I’ll give you several examples of bird species that depend on grassland habitats. And we’ll also talk a bit about grassland conservation. Because you know we can’t get through this without a little gloom and doom.

	04 Dec 2022	Waxwings	00:46:43
This is Episode 65, and it’s all about waxwings—birds in the family Bombycillidae. The Cedar Waxwing is one species, and there are two others that we’ll talk about. These beautiful, elegant songbirds are loved by people across the Northern Hemisphere. Waxwings are easy on the eyes, for sure, and that’s great. I mean, personally, I think they’re just about the most gorgeous songbirds we have in North America. But their biology is also really interesting. So much of how waxwings live and behave is dictated by what they eat… By their specialized diet. What is that special diet? Is it maybe something like scorpions, psychedelic mushrooms, or the blood of their enemies? Listen and find out!

	15 Dec 2022	15 Simple (and Several Complicated) Ways You Can Help Birds	00:24:41
This episode—which is Number 66—is all about the ways you can help birds. How you can make a difference in their conservation. It’s one thing to enjoy learning about birds in an objective, scientific way. They’re fascinating organisms. But does our interest in the biology of birds also come bundled with a care and concern for them? With warm and fuzzy feelings? I’d say heck yes, it does! For most of us, anyway, including yours truly. We want birds out there in the wide world to survive and thrive. For their own intrinsic worth as living beings. But also because of our selfish desire to have them around for us—so we can enjoy them, and take Instagram-worthy photos of them, and write their names down on our lifelists.

This is Episode Number 67. It’s the last episode of 2022, so that means it’s the Annual Review! We’re going to look back at 2022, at some of the most interesting scientific studies of birds that were published this year. Will this be a painstakingly thorough review of everything that scientists learned about birds in 2022? No. Not so much. The studies I’m telling you about today—while they did make it into the newsfeed—are just the ones that I found most exciting. Or at least interesting.

	16 Jan 2023	Hornbills	00:53:50
Today’s episode is number 68. It’s all about the family of birds called Bucerotidae. These are the hornbills. Maybe you’ve heard about hornbills and know a few facts about them. Or maybe you’ve never even heard about these birds. Either way, I think you’ll enjoy today’s podcast episode. Hornbills are just so cool! The family Bucerotidae includes several dozen hornbill species. But there’s a second, much smaller avian family that contains birds we also call hornbills. The name of that family is Bucorvidae, the ‘ground-hornbills.’ There are only 2 species of ground-hornbills. I’ll be including them in our conversation today too. Besides, until recently, scientists grouped ground-hornbills into the larger Bucerotidae family. Hornbill are key players in the tropical ecosystems of both Africa and Asia. There are many fascinating things for us to learn about them.

	13 Mar 2023	Hurricanes and Heatwaves: How Does Extreme Weather Affect Birds?	00:42:01
This episode—which is Number 72—is about what happens to birds, not just in bad weather, but in really bad weather. We’re talking hurricanes, floods, droughts, heat waves, tornadoes, maybe even the occasional sharknado, and so on. How do birds deal with all these natural disasters? We’ll get into that. We'll be talking mostly about the more immediate effects of storms and other extreme weather on the survival of individual birds and their populations. Birds are tough little buggers. They’re tougher than they might look. Many of them live long lives in the face of continual challenges like predators, aggressive rivals, wild temperature swings, strong wind, and heavy precipitation. But an extreme weather event can often be the ultimate test of survival for a bird.

This is Episode 73. It’s all about birds in the avian family Gruidae… the cranes. These tall birds are charismatic and super interesting. It’s going to be fun to do a deep dive into all things crane today. Humans around the world have celebrated cranes for thousands of years, for their graceful beauty and their exuberant courtship dances. Across many cultures, cranes have inspired paintings, songs, dances, legends, martial arts, heavy construction machinery apparently, and the most iconic animal design in the fine art of origami. It’s spring in the Northern Hemisphere right now, and that means that in many parts of the world, cranes are on the move. They’re migrating north. Along the way, they stop to rest and refuel at certain staging areas. Hundreds or thousands of cranes can end up at a single staging area or stopover and this can be a wonderful sight to see for birders and other nature lovers. There are a bunch of crane festivals around this time every year. It’s a rare thing for any kind of bird to get so much attention and adoration like this. Cranes are just that special. So how about we have our own little crane festival today. Let’s get to know these amazing birds.

	14 Apr 2023	Where Does Bird's Nest Soup Come From?	00:35:20
This episode—which is Number 74—is all about edible bird’s nests and Bird’s Nest Soup. Edible bird nests are a traditional delicacy in east Asia. Especially in China. For centuries, wealthy Chinese people have consumed edible bird nests. Usually in the form of bird’s nest soup. Throughout much of recent history, this dish has been one of the most expensive foods in the world. No wonder people have called edible bird nests the “caviar of the east,” or “white gold.” Perhaps the primary reason people spend ungodly amounts of money on bird’s nest soup is because of its medicinal properties. Well… It’s supposed medicinal properties, anyway. In traditional Chinese medicine, it’s believed that the benefits you can get from eating these nests include: a prolonged life, increased attractiveness, increased libido, brain health, bone strength, no more diabetes, no more cancer, a stronger immune system, more energy, better looking skin, and better circulation. Wow. So basically, it sounds like an edible bird’s nest is a cure-all—a panacea. That’s pretty impressive! But is it true? And where do these nests come from? What do they look like? In today's episode, we'll get into all of that. We’ll talk about which birds make these amazing nests, and how they do it. We’ll also look at the way people harvest edible bird’s nests, the global industry for this product, and some ethical concerns.

	08 May 2023	Shrikes	00:46:02
This is Episode 75. It’s all about shrikes—birds in the family Laniidae. These are true songbirds—members of the avian suborder Passeri within the order Passeriformes—even though they act (and sort of look like) tiny falcons or hawks. Shrikes are sit and wait predators. They typically sit upright on an exposed, conspicuous perch and then wait for something tasty to come along. Some small animal, like a Vesper Sparrow, a rodent, lizard, grasshopper, and so on. Shrikes are such cool birds that they have many fans among ornithologists. In fact, there’s a subdiscipline of ornithology called shrikeology. For real. And those who study these fascinating birds are known as shrikeologists. So for today, at least, let’s all be honorary shrikeologists. Let’s get down to the nitty-gritty details of shrike biology.

	09 Jun 2023	Seabirds	01:06:41
This is Episode 77. It's an overview of seabirds. Some might call them Oceanic birds or Marine Birds. How do we define what is or isn’t a sea bird? Well, it depends on who you ask. There’s no one definition, since “seabird” is an informal term, rather than a scientific one. It doesn’t correspond to a single taxonomic category, or to a single evolutionary lineage. Here’s what the authors of the book Oceanic Birds of the World have to say about it: “To our mind, true seabirds are birds of the ocean, birds you generally go on a boat to see. Yes, some of these species can be seen from shore (and almost all come ashore somewhere to breed), but the birds we include here are species that make their living from the ocean for all or most of the year, and often not from coastal waters.” Oceanic Birds of the World is a field guide, and it includes about 270 species.

	22 Jun 2023	Parental Care: How Birds Raise Their Young	00:46:30
This is Episode 78 and today we’re doing an overview of parental care in birds. How do birds raise their babies? Parent birds feeding their chicks in a nest is an iconic image. It’s a symbol of the spring and summer seasons and of the annual rejuvenation of nature. To the casual observer, birds generally come across as caring, attentive parents. Similar to the way mammals demonstrate good parenting behavior. We humans approve of this sort of thing. It makes us feel all warm and fuzzy inside. I mean, the behavior of birds and mammals is way better than what amphibians and reptiles do, right? Those cold-blooded critters just crank out a bunch of babies and then leave them to fend for themselves. No parental care to speak of. Despicable! But to be fair, birds aren’t always the paragons of parental love that we might think they are. They sometimes do pretty messed up things when it comes to raising their offspring. And this highlights the fact that humans like to project our own cultural values onto animals. If, for example, we see a pair of adult geese dutifully tending to their adorable, fuzzy chicks, we might think, “Aww… What a cute little family. They all love each other.” And when we hear about a female Blue-footed Booby that did nothing and just sat there indifferently while the older of her two chicks murdered its younger sibling… Well, in that case, we’d probably think that booby is a bad mommy. She should be locked up in bird prison, if there were such a thing. I’ll admit I’m often guilty of this sort of thinking. I like to think that birds love their babies. I’m a total sucker for heartwarming scenes of parental care in birds. But I also know it’s not really fair for us to judge birds based on human ideas of right and wrong. Birds are just being birds. They do whatever it takes to survive and reproduce in a challenging and mostly unpredictable world. Bird Conservancy of the Rockies [Learn More] Bird Merch — Get yourself some bird shirts!

	18 Jul 2023	Red-tailed Hawk	00:50:32
This is Episode 79. It's all about the Red-tailed Hawk (Buteo jamaicensis). This is one of North America’s most common raptors. We find these birds from sea to shining sea across the continent. The Redtail is a generalist predator. It can eat many kinds of prey and thrive in a broad range of habitats. Besides seeing these birds along the highway, you’re likely to spot a Red-tailed Hawk circling in the sky over a field, soaring or flapping slowly. In this episode, I cover the key traits of the Red-tailed Hawk, it's diet, and its breeding behaviors.

	03 Aug 2023	Earthbound: How Birds Become Flightless	00:54:58
This is Episode 80. It's all about flightless birds, and about the evolutionary processes that lead to flightlessness. Flightlessness in birds is, in my opinion, a fascinating scientific topic. And so here we are with this episode. Alive on the planet today, there are about 60 bird species that can’t fly. That’s only about 0.54 percent of the world’s approximately 11,000 species. It turns out there were way more flightless bird species out there before humans started exploring and colonizing every corner of the Earth. It wasn’t just the Dodo that was killed off by people. In today’s episode, we’ll look at the wonderful diversity of flightless bird species—in both the present and the past. We’ll also talk about conservation and—perhaps the most interesting thing—the evolutionary process that leads to flightlessness. How does this weird thing happen in nature?

The focus of today’s episode is not so much about the behaviors of birds, but about the technologies used by researchers to study bird behavior—the methods used to reveal the movements of birds. And our focus will be on the tracking of individual birds. There are other methods scientists use to record the mass movements of birds, like using radar to track flocks of migrants. But today we’re looking at techniques that can reveal the unique paths taken by an individual bird—a sandpiper, a hawk, albatross, pheasant, penguin, or whoever.

	25 Sep 2023	Quails of the New World	01:05:10
This is Episode 83. It’s all about birds in the family Odontophoridae. These are the New World quails. Why is this the family of "New World" quails? Because there’s a whole mess of birds we call quails that live in Europe, Asia, Africa, and Australia. But those birds all belong to the pheasant family, Phasianidae. New World quails are shy birds ground-dwelling birds that walk or run around in the daytime, looking for tidbits of food in the leaf litter. If they sense any kind of stranger danger, they hunker down and hide in bushes or other vegetation. Their first instinct is to sit still and rely on their camouflage, rather than to fly away. These birds may be shy around strangers, but they’re generally very social with members of their own kind. They’re gregarious little buggers. In this episode, I go into detail about what New World quails look and sound like, about their diversity, and about the ways they live their lives. ~~ Leave me a review using Podchaser ~~ Link to this episode on the Science of Birds website Bird Conservancy of the Rockies [Learn More] Bird Merch — Get yourself some bird shirts!

	09 Oct 2023	Saving Bird Species From the Brink of Extinction	00:54:31
This is Episode 84. Our topic today is the challenge of saving bird species that are very close to extinction. Species like the Spix’s Macaw, which have tiny global populations—whether in the wild, or in captivity. Other familiar examples are the California Condor and the Whooping Crane, whose populations bottomed out at 22 and 23, respectively. Rigorous conservation programs have since given these two North American species a fighting chance at long-term survival. This episode is about species that we almost lost forever, but with great effort we’ve kept them from disappearing. Many of these species, like the California Condor, aren’t out of the woods yet. They may be in better shape now than they were a couple of decades ago, but they still need lots of help. In this episode, we’re first going to look at some of the biggest challenges faced by conservationists as they try to save species on the brink.

This comes from an announcement made by the American Ornithological Society just a few weeks ago, on November 1st. I couldn’t pass up the chance to talk about this. It’s a hot topic among birders right now. People have been asking me what I think about all these birds getting renamed. And so here we are. If you’re hearing about this for the first time, and you don’t know what I’m talking about, don’t worry—I’ll explain. Yes, this is primarily relevant to birds and the humans who love them in the Western Hemisphere. Mostly North America for now. But similar changes may be on the horizon for your local birds, wherever you live. So I think you’ll find this interesting, even if you don’t live in the US or Canada.

The definition of ornithophily is “the pollination of flowers by birds.” Today, I’ll be focusing mostly on the ecological relationships between plants and the birds that pollinate them. Another way to look at all of this would be through the lens of evolution—the fascinating ways that plants and birds have co-evolved with respect to pollination. I’ll make another podcast episode, at some point, about bird and plant co-evolution. We’ll touch on it today, but the main focus is ecology.

I’ve had a lot of requests to make a podcast episode about chickadees and their kind. Some species in this family are familiar visitors to backyard bird feeders. They’re highly active, vocal, bold, and sometimes quite confiding with people. It’s possible to gain the trust of tits and chickadees of some species by feeding them seeds out of the palm of your hand. These birds not only visit bird feeders regularly, at least in winter, but they’ll also happily lay eggs in artificial nest boxes. All of these traits make birds in the Paridae family great subjects for scientists who want to study bird behavior and ecology. So chickadees, tits, and titmice are among the most well-studied songbirds on the planet.

	29 Feb 2024	Bird Habitat: Deserts	01:08:24
This episode—which is Number 92—is all about the value of desert ecosystems as habitats for birds. Deserts are important for the birds that are adapted to live in them—birds that can handle the harsh conditions. Deserts are home to relatively few bird species. Only the polar regions and maybe some parts of the open ocean have less bird diversity. Even if a bird species can handle the extremes of heat and cold in a desert, the desiccating winds, and the lack of water, that bird may not find much food. Because where there are few plants, there are few invertebrates. So a bird in the desert can have a hard time finding any leaves, seeds, fruit, or bugs to eat. And yet, an assortment of bird species from many disparate families have managed to carve out an existence in the world’s most arid lands. There may be nowhere near as many of them as in, say, a tropical rainforest or a temperate woodland… BUT, the birds we do find in the desert are, I think, a particularly fascinating and admirable bunch. They’re tough little buggers. They’re resilient. Desert birds have interesting adaptations and behaviors that allow them to survive in places that would kill most other birds in a day.

These sleek, hook-billed birds are known for their distinctive silhouettes, often seen drying their wings on seaside cliffs or wetland trees. Cormorants and shags have a long history of varied human interactions, from being vilified and hunted to being revered and even trained to catch fish. These birds are exceptional divers, utilizing their streamlined bodies and webbed feet to hunt underwater. Their feathers are less waterproof than those of other aquatic birds, which aids in diving but necessitates their iconic wing-drying behavior. Cormorants can be found across the world, thriving in diverse habitats from coastal cliffs to freshwater lakes. They face significant conservation challenges. Human persecution and disturbances, habitat destruction, and climate change threaten several species, some of which are critically endangered.

	01 Aug 2024	The Evolution of Feathers	00:42:54
This is Episode 101. Today, we trace the origins of feathers back millions of years, exploring how they evolved from simple filaments to the complex structures we see in modern birds. We delve into the discovery of feathered dinosaurs like Archaeopteryx and the numerous fossil finds in northeastern China during the 1990s. These discoveries revealed that many non-avian dinosaurs sported feathers of various types and complexities, indicating that feathers were not unique to birds but were a common feature among many dinosaur lineages. The evolutionary journey of feathers showcases their initial roles in insulation, display, and possibly tactile sensation, long before they were adapted for flight. Join me as we walk through the Five-Stage Model of feather evolution, which parallels feather development in modern birds.

This episode—which is Number 104—is all about rocky shores and sandy beaches as bird habitat. These environments offer birds very different resources and challenges. We explore the geology behind these habitats—how high-energy waves shape rocky cliffs and headlands, while the deposition of sediment builds up sandy beaches. Alongside this, we discuss the dynamic interaction between birds and their coastal homes, and how species like gulls, shorebirds, and seabirds have adapted to thrive in these unique settings. The episode highlights the incredible diversity of bird species found along coastlines worldwide. From puffins nesting on rocky sea cliffs to plovers skittering across sandy beaches, coastal birds have developed specialized feeding and breeding behaviors to survive in their often harsh environments. We also examine how tides and wave energy shape the coastal ecosystem and offer rich feeding opportunities for birds during migration and in their non-breeding seasons. Finally, we touch on the many challenges coastal birds face from human activity—habitat destruction, disturbance, pollution, and climate change—all of which threaten these delicate ecosystems. But amidst the challenges, coastal environments remain awe-inspiring places for birdwatching, providing opportunities to witness some of the most dramatic bird spectacles on Earth. ~~ Leave me a review using Podchaser ~~ Link to this episode on the Science of Birds website Bird Conservancy of the Rockies [Learn More] Bird Merch — Get yourself some bird shirts!

This is Episode 105. It’s all about a small group of birds called mergansers. These are diving ducks known for their skill at catching fish. They have long, slender bills with serrated edges, earning them the nickname "sawbills." Maybe you’re familiar with these birds. Maybe you’re already a big fan. Or maybe you didn’t know they existed until just now. Either way, our goal today is to learn a lot more about Common Mergansers and their close relatives. There are five species that we call mergansers. And there’s another species in this group that’s called the Smew. The Smew is sort of an honorary merganser. The six species we’re looking at today are divided among 3 genera. Of all the ducks in the world, mergansers are the species that depend the most on fish. So not surprisingly, they’re excellent divers and swimmers.

	16 Feb 2025	Crossbills	00:53:06
In this episode, which is number 111, Ivan Phillipsen explores the fascinating world of crossbills, a unique group of finches with an extraordinary beak adaptation. These birds, found across North America, Europe, and Asia, use their specialized crossed bills to extract seeds from conifer cones—a skill few other birds possess. Ivan discusses the six recognized crossbill species, their distinct feeding strategies, and how their beaks evolved for this specialized diet. The episode highlights the complex classification of crossbills, particularly the Red Crossbill, which has multiple "call types" that may represent different evolutionary paths. Ivan explains how these birds are nomadic, moving vast distances in search of conifer seed crops, and how some species, like the Cassia Crossbill, have adapted to specific tree species. The episode also covers the recent debate in the ornithological community about whether certain crossbill populations should be considered full species. Additionally, Ivan discusses how crossbills’ courtship behavior, nesting habits, and vocalizations vary among species.
