Comments:

 

The steady rain early this morning was daunting, but it dwindled to a fine mist at RBR and eventually cleared to partly sunny through the morning. This weather shift brought out some nice bird activity in excellent light. Juveniles of many species were observed, including white-crowned sparrows whose crown stripes were in mid-change from buffy/brown to black/white. We had the chance to study an orange-crowned warbler, noting the dark eyeline, yellow undertail coverts, and pale gray streaks on the breast. We also observed Brewer's blackbirds in a flock of males and females, with some females having the pale iris and others having the dark iris. We were able to compare Lincoln's and Song sparrows, and observed the distinctive upward tail posture of the blue-gray gnatcatcher. The peregrine capped off the morning as we observed it perched for some time before it flew off. We can expect more excellent fall birding through early October meeting at Hallam Lake in Aspen- join us as we chase mixed flocks of great warblers, bushtits, and more!
