Morning Birding at Rock Bottom Ranch Species List
September 1, 2020
Tuesday, September 1, 2020 7:30AM – 10:30AM
Weather: Sunny and cool.
Location: Rock Bottom Ranch
Flocks of western wood-pewees and Wilson’s warblers were especially active in the shrub understory and riparian areas as well as in brush piles and fencerows today at the ranch. Adult starlings were seen in non-breeding plumage as well as a juvenile that was in mid-molt. A family of Lewis’s woodpeckers was active near the parking lot. Swallows have mostly left the upper valley at this point, although they are still numerous in the mid-valley. We saw a large mixed flock of violet-greens and barns foraging over the ranch this morning. A particular highlight was a pair of soras that were foraging along the edge of the cattails that ring the pond by the bird blind. They stayed in view for around 10 minutes, allowing us to get familiar with their field marks and behavior. Our mini lesson focused on fall migration: an estimated 5 billion birds migrate in the fall in North America, a high number bolstered by the young of the year. Examples of birds that migrate during the day include pelicans, hawks, falcons, hummingbirds, and swifts. Those that migrate during the night include warblers, flycatchers, orioles, thrushes, and blackbirds. Join us on Thursday for a birding field trip in the Gorge of the Roaring Fork!
