Morning Birding at Rock Bottom Ranch 9/28/21

Tuesday, September 28, 2021, 7:30am-10:30am
Weather: Mostly Cloudy
Location: Rock Bottom Ranch

Fall migrants are still refueling and feeding in areas of rich food resources in the valley, and today we noted orange-crowned and Wilson’s warblers and ruby-crowned kinglets foraging in mountain shrublands and scattered stands of cottonwoods. An adult sora on the far pond and a flock of bushtits along the Rio Grande Trail were special highlights. Ducks are molting into breeding plumage, showing widely varying stages of progress. Starlings are also now in their non-breeding plumage, covered with white spangles. We discussed the hazards of migration and appreciated the long distances flown annually by some of the species we saw. Join us next Tuesday for morning birding at Hallam Lake!
