As the main migration season winds down here in southern Arizona, the later migrants (some of them only infrequently encountered) can put in an appearance. White-rumped Sandpipers, Yellow-billed Cuckoos, Thick-billed Kingbirds, Blue Grosbeaks and Varied Buntings all tend to lag the other arrivals. Today Alan spotted a regular but very scarce migrant, which came to our yard for a sip of water: a Swainson’s Thrush!
The buffy spectacle and lack of rust in the tail help to rule out the similar Hermit Thrush, a much more common resident of the Chiricahua Mountains.
Over the past 15 years while working in the bootheel of New Mexico, Alan and I have only encountered Swainson’s Thrushes on four occasions, twice while banding at Clanton Cienaga. They seem to move through the region during a narrow window of time, from about May 11 through about May 31. That’s now, so ¡ojo! –– keep your eyes open!
