As predicted by Kim Boodie, the count did pick up on Sunday with a fair diversity of 87 raptors moving through and 79 Turkey Vultures. Interestingly, Bonney Butte had 48 raptors and 22 TVs on the same day, with the same conditions but with 3 more hours of observation. (They run from 8:00 till 6:00 whereas we run from 10:00 till 5:00.) Sunday's observers were Peter Low, Judy Meredith, Chuck Gates, Satch and Nancy Esperancilla with three visitors. Birds moved through at a steady rate mainly low on the east side in the morning. Due to the lack of significant winds the birds went high overhead on thermals in the afternoon with a couple of exciting bursts of activity after Peter had left, unfortunately. It was the second day without a Kestrel. (Bonney Butte has documented a 5.37% average decrease for this species from 1994 through 2004.)
