AMERICAN ROBIN WY-244
Grand Teton National Park, Wyoming
May 31, 5:51 a.m.
Sunrise at 5:45 a.m.
About 20 yards away up in the top of a spruce tree he sings, racing through his repertoire of carols and hissellys. The norm is two or three carols followed by one or two hissellys, about a song every second, 60 per minute.
As I watch the sonagrams fly by on the computer monitor, I can pick out both carols and hissellys that recur, and I marvel at all that he has in his head and how he has chosen to play it all out.
Background
Wilson's snipe winnows, and general songbird chorus in the background.
