Join BirdNote tomorrow, November 30th!
Illustrator David Sibley and actor H. Jon Benjamin will face off in the bird illustration battle of the century during BirdNote's Year-end Celebration and Auction!
When a Sage Thrasher, perched on a clump of sagebrush, tips its head back to sing, the notes rush forth. They often sing non-stop for at least two minutes. In stark comparison, the song of this Brewer’s Blackbird lasts barely a second. And the Henslow’s Sparrow values brevity even more. But whether they’re long and drawn out or short and sweet, bird songs are all about the same things: territory and breeding.

Voices & Vocabularies: Songs Long and Short
Written by Bob Sundstrom
This is BirdNote.
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, http://macaulaylibrary.org/audio/175693, 0.33-45]
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 Brewer’s Blackbird, singing to the world from atop a fence post, sounds brusque. [Brewer’s Blackbird song, http://macaulaylibrary.org/audio/188802, 1.12.]
One full song from a Brewer’s Blackbird lasts barely a second. [Brewer’s Blackbird song, http://macaulaylibrary.org/audio/188802, 1.12]
Amazingly, a Henslow’s Sparrow values brevity even more. [Henslow’s Sparrow song, http://macaulaylibrary.org/audio/189892, 0.13]
That was it. In case you missed it…here it is again. [Henslow’s Sparrow song, http://macaulaylibrary.org/audio/189892, 0.13]
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, http://macaulaylibrary.org/audio/175693; 0.48-.55]
As for the Sage Thrasher? He’s still going strong . . . [Sage Thrasher song, http://macaulaylibrary.org/audio/175693; 0.48-.55]
