Today’s mini-lesson addressed bird migration and the various cues and mechanisms involved, including day-length, hormones, internal compass, and the ability to see polarized light and sense the earth’s magnetic field. In the field, we had great looks at sandpipers, swallows, a Cordilleran flycatcher foraging for insects on the ground (which is unusual), and many yellow warblers.  Special highlights were seeing the dipper nest on a bridge over the Roaring Fork River, and seeing one of the adult great horned owls attending the fledgling from the active nest near the library. Summer activity is in full swing, and there is much more amazing birding coming up through the summer!
