Hallam Lake highlights were Spotted Sandpiper chicks and great looks at Song Sparrows. We discussed the reversed role system that Sandpipers use, in that the males raise the brood and the females defend territories. At the Music School campus we were treated to lots of nesting and fledgling activity. A family of Dippers was feeding in Castle Creek which was still flowing quite high. The dippers used the few streamside rocks that were exposed for perching, as well as low willow branches overhanging the water. A family of Mountain Chickadees was foraging in another willow thicket, a pair of Cedar Waxwings was constructing a nest in a Douglas fir tree, and two pairs of Cordilleran Flycatchers were nesting within 100 yards of each other- one in a hole in the siding of a small shed, and the other on a siren horn mounted on the side of another building- showing Cordillerans’ propensity for nesting on human-made structures and in close proximity to activity.
