ACES Morning Birding at Hallam Lake 8/8/23

Tuesday, August 8, 2023, 7:30-10:30am
Weather: Mostly Sunny
Location: Hallam Lake, Aspen, CO

Singing and nesting activities are gradually shifting to dispersal and staging for migratory species, and food-caching for certain resident species. We observed Swallows flocking, one of the earliest groups of birds to leave at the end of summer. Swallows will leave our local skies by about Labor Day weekend. The Osprey family was feeding its two large chicks at the nest, giving us great views of lots of activity. We expect the chicks to leave the nest any time. One Great Blue Heron chick was visible in the heronry above the lake, the others nests being empty as the chicks are gradually becoming independent. Yellow Warblers foraged among the willows, an American Dipper gave some of us a fleeting glimpse on the river, and Robins gathered in service berry bushes to feast on the ripe berries. Join us next week for Morning Birding at Rock Bottom Ranch!
