The first documentation of a White-tailed Kite (Elanus leucurus) in Arizona was obtained when Ellis photographed an adult on 11 August 1978 in the Altar Valley, Pima County. The record was made along the Elkhorn Ranch (Sabino Canyon) road about 5 km west of Arizona Route 286 (31°49′N, 111°27′W). The photograph is on deposit at the Department of Ecology and Evolutionary Biology at the University of Arizona, Tucson (No. 13377). The photograph, although not of good quality, shows the following diagnostic features: dark primaries contrasting with light secondaries; dark wrist mark on under wing coverts; light head, tail, and underparts; heavily feathered tibio-tarsus. The dark lesser coverts of the more distant wing are less clear. The general shape of the bird is also characteristic.
