This field trip explored birds in a variety of native habitats on a loop route crossing Deer Hill, descending Burlingorge Trail to the Roaring Fork River, and coming back up on a connector trail to the AABC.  The gorge of the Roaring Fork is fascinating geologically, with Red Butte’s upside-down rock layers and the steep gorge walls that cut through glacial debris and shale layers.  The geology and topography set the stage for rich vegetation communities such as oak mountain shrubland, open meadows, fragments of sagebrush shrubland, weedy patches, cottonwood river bottom, and mixed forests of Douglas fir, spruce, and aspen.  Fall brings migrating songbirds to this area where foods are abundant.  Our first positive ID on the trail was a Nashville Warbler, an uncommon migratory species in our area,  Other highlights included Olive-sided flycatcher and western wood-pewee side-by-side for an amazing comparison of these similar birds; an excellent viewing of Townsend’s warbler; and an abundance of sparrows that gave us lots of practice with their subtle field marks and variations in plumages.  We all enjoyed sharing discussions and observations, and everyone came away with some new and reinforced knowledge of the birds.  Join us next Tuesday for Morning Birding at Hallam Lake!
