CURWOOD: One of the great pleasures of spring is the birdsong thats suddenly all around us from before dawn till way beyond dusk. And the tunes these songsters create are as varied as they are, as Mary McCann explains in todays BirdNote. BirdNote Voices & Vocabularies: Songs Long and Short MCCANN: Bird songs come in many shapes and sizes. When a Sage Thrasher, perched atop a clump of sagebrush, tips its head back to sing, the notes rush forth. [Sage Thrasher song] What you just heard is a mere snippet. Sage Thrashers often sing non-stop for at least two minutes, and can go on for more than twenty. In stark comparison, a Brewers Blackbird, singing to the world from atop a fence post, sounds brusque. [Brewers Blackbird song] One full song from a Brewers Blackbird lasts barely a second.

[Henslows Sparrow song] But whether long-drawn-out or short-and-sweet, bird songs are all about the same things: territory and breeding. Claiming a space and attracting a mate. Once those are sorted out, further singing by the male is all about keeping his territory intact. [Sage Thrasher song] As for the Sage Thrasher? Hes still going strong...
