This is the first 45 minutes of the summer dawn chorus in Carman Valley, Sierra, California recorded by Gregory Budney at 4:30 AM on June 12, 1994.

The sounds were labeled by me, Alex Smolyanskaya, with the help of my wonderful ear birding friends and mentors. If you spot any errors please send them to @asmoly.

My tools and references included Raven Lite, R, Peterson's Field Guide to Bird Sounds of Western North America by Nathan Pieplow, and Birdgram (iOS).
