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 I...
Apr 06, 2022•52 min•Transcript available on Metacast 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 inter species dominance. But today, we’re talking about intra species do...

Feb 18, 2022•19 min•Ep 46•Transcript available on Metacast 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,...

Dec 30, 2021•38 min•Ep 42•Transcript available on Metacast This episode is all about birds in the family Hirundinidae. These are the swallows and martins. Other than when they’re nesting, swallows are in the air almost all day long. This aerial lifestyle and that high-speed, erratic flight pattern can make it hard for us earthbound primates to get close looks at swallows. But these flappy little birds definitely deserve our attention. They have many charms and talents that—with a little patience—we can learn about and see for ourselves. ~~ Leave me a re...
Dec 23, 2021•49 min•Transcript available on Metacast Ecologists and ornithologists have been studying the effects of wildfire on bird populations all over the world. Their research has resulted in many fascinating discoveries about the relationships between fire and birds. Wildfires have been in the news a lot in recent years. In the western US where I live, enormous fires have been sweeping across California, Oregon, Idaho, and other states with increasing frequency and severity. And who can forget the 2019-2020 bushfire season in Australia, whic...

This group includes species like the Turkey Vulture, Black Vulture, and Andean Condor. Among these birds are some that people celebrate, or even revere. But others tend to get ignored, disparaged, or at worst, persecuted. I guess you could say our relationship with New World Vultures has been… complicated. ~~ Leave me a review using Podchaser ~~ Support the show...
Nov 03, 2021•51 min•Ep 38•Transcript available on Metacast Birds, probably more than any other aerial creatures, have amazed and inspired us with the grace and power of their flight. So just how do they do it? In this episode, we'll look at the physics and anatomy of bird flight. I’ll start off with the basics of aerodynamics as it relates to bird flight. That’s the meat and potatoes of our lesson today. But we’ll also consider the different ways that birds fly—their different modes of flight. Last, we’ll examine some additional adaptations birds h...
Oct 20, 2021•36 min•Ep 37•Transcript available on Metacast This episode is all about penguins. All penguins belong to the family Spheniscidae. Penguins are among the most bizarre and specialized birds in the world. Few other birds represent such a departure from what we think of as the standard avian model. The specializations of penguins—their adaptations—serve them very well for a life of diving deep into the ocean and of surviving in extreme cold. These birds are wonderful examples of how “life finds a way”—how animals can evolve into radically diffe...

People in North America have revered the Greater Roadrunner for thousands of years. This bird features prominently in Native American and Mexican legends and lore. It’s usually depicted in a good light. Roadrunners are bold, clever, and fast—all admirable characteristics. They’re also large and conspicuous birds, so it’s not surprising that more than one cultu...

A lot of what we’re talking about today has to do with sexual selection , which is a special form of natural selection. In sexual selection, individuals compete for mates. This is when females and males choose their partners based on specific traits. Traits like plumage color or song, behavior, etc. This choosiness has resulted in some spectacular features in birds. Many of the things we love m...
