In late afternoon went with Rodgers to reddish Butte E. camp. Observations of note: - Cassin Kingbird & Prairie Falcon (In A.M., saw two Cassin Kingbirds, one being chased by a Prairie Falcon and the other Cassin chasing the Prairie Falcon. Kingbirds were uttering different note than ordinary and more common Wastura; may be written as cree-dee, accent on both syllables and very closely run together. This series given in rapid sequence. Chase didn't last long & Falcon continued low our wash down canyon. Light-tipped tail, no white on outer edge of rectrices was easily seen). - Gray Titmouse (Johnson showed me nest in single bran unbranched, dead Joshua stick in rocky habitat, near Junipers on side Canyon of photographer Cedar Canyon.
