Happy Global Big Day from Costa Rica!
10,000 Birds
MAY 14, 2016
This Yellow Warbler was looking fresh before it left Costa Rica. The Cornell team is no doubt having a fantastic day of birding up there in beautiful spring Colorado while they identify Cassin’s Sparrow, Prairie Falcon, Lazuli Bunting , and other western birds in some of the same places I surveyed in 1997 and 2001.
