This episode—which is Number 94— is all about the Avian Digestive System. That’s right, kids, we’re looking at bird guts today!If you’ve ever wondered what happens to a fish swallowed by a kingfisher or what happened to that piece of bacon swiped off your lunch plate by a cheeky Ring-billed Gull... Well, you're about to find out.I’ll do my best to describe in words the anatomical features we encounter today. But I’ve also drawn a diagram for you. You can check that out on the show notes for this episode on the Science of Birds website. ~~ Leave me a review using Podchaser ~~

This episode—which is number 93—is all about the the House Sparrow (Passer domesticus), one of the world’s best known and most abundant birds. It expanded across the planet along with humans over the last 10,000 years, with the spread of agriculture. Today, this plucky little bird is a model organism for the study of basic bird biology. Over 7,000 scientific studies of the House Sparrow have been published. In this episode, we’ll get into what this species looks and sounds like, where it lives, its behavior, its breeding biology, and more.Links of Interest

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.CORRECTIONS: I realized after I recorded this episode that I mispronounced the names of the Namib and Thar deserts. Namib should be pronounced "NAH-mib." Thar is pronounced "Tar."

This is Episode 91. It’s all about birds in the family Paridae. These are the chickadees, tits, and titmice—cute little forest-dwelling songbirds known and loved by many people around the world.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. Lucky for us here on The Science of Birds podcast, that means there’s a lot we can learn about them

This is Episode 90 and it’s all about the importance of birds as plant pollinators.If I had to use only one word for the topic of this episode, it would be ornithophily. 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. Pollination ecology is actually an entire subdiscipline that many scientists have dedicated their careers to studying. It’s really interesting stuff!

This is Episode 89. I’m publishing it right at the beginning of 2024, and it's a review of some fascinating things that happened in the world of ornithology and bird conservation over the last 12 months, in 2023.Naturally, this isn’t an exhaustive review of every scientific discovery about birds in 2023. That would be too much. An exhaustive review would be, well, exhausting. Maybe not for you, but definitely for me.Instead, I’ll tell you about a handful of studies and projects that I think you’ll find interesting. These gems were hand-selected by me for your educational pleasure.Links of Interest

This episode—which is number 88—is all about owls. Owls are fascinating birds that have captured our imaginations since the dawn of humankind. They have amazing camouflage that allows them to blend in with their surroundings, and they have several other avian superpowers that set them apart from all other birds. Owls are divided into two families—Tytonidae and Strigidae—and we'll be discussing both of them today.Links of Interest

This episode—which is Number 87—is all about some big news in the birding world. The common names for about 150 North American bird species are going to change in the not-too-distant future.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.

This episode—which is Number 86—is all about bird beaks.This will be an overview of beak anatomy, function, evolution, and diversity.The head of every bird on Earth is adorned with a beak. A bill. And to the delight of us all, those beaks come in a wild variety of shapes and colors. Just picture the mugs of toucans, vultures, ducks, parrots, flamingos, and pelicans.The diversity of beak shapes like these is one of the fascinating things about birds. Birds use their beaks for all sorts of tasks. These appendages are vital tools, used for getting food, for grooming, for communication, and more. Links of Interest

This episode—which is Number 85—is about the Meadowlarks of the world.And it’s not just those three North American species: the Western, Eastern, and Chihuahuan. There are actually 8 bird species we call meadowlarks. The other five are found primarily in South America. We’ll be talking about them today, too.Meadowlarks belong to the New World Blackbird family, Icteridae. This family includes birds like Red-winged Blackbird, Baltimore Oriole, and the Great-tailed Grackle.There’s a lot to admire about meadowlarks. The 3 yellow-breasted and 5 red-breasted meadowlark species bring color and music to the windswept grasslands of the Americas. ~~ Leave me a review using Podchaser ~~
