Today’s mini-lesson emphasized the mixed fall flocks of warblers, chickadees, kinglets, and vireos, and we saw this phenomenon in many places along our route, especially in the mixed shrubs with grassy openings. We enjoyed the abundance of birds, gathering in groups and shifting positions to try to get views of them as they darted between shrubs and moved among foliage. Highlights were the warblers that we were able to study in order to compare their unique fall field marks, and a wild turkey that had flushed up into a cottonwood tree at our turn-around point on the Rio Grande Trail. Turkey vultures were circling in thermals over the valley in groups of a dozen or more, perhaps gathering and traveling on their southward migration. Join us next Tuesday at Hallam Lake for more fall migration birding!
