Roger Tory Peterson, the best known American figure of 20th Century birdwatching, offered help on birding by ear. Whenever he could, he provided a catchphrase to identify a bird's song. "Witchety-witchety-witchety" captures the song of this Common Yellowthroat. The California Quail seems…

If you're near High Island, Texas in the spring, you might witness a "fallout," one of the great spectacles of bird migration. Thousands of birds, including Rose-breasted Grosbeaks, orioles, Painted Buntings, and warblers of all kinds, as well as tanagers and Indigo Buntings, like this one…

Happy Mother's Day, from the whole BirdNote team! Avian motherhood is a mixed bag. Peregrine Falcon mothers share duties fairly equally with Peregrine dads. At the other end of the spectrum is the female hummingbird, which usually carries the entire burden of nesting, incubating, and…
