Sinaloa Wren (Thryothorus sinaloa), Huachuca Canyon, Cochise County

This Sinaloa Wren was discovered by Ron Beck on 02 September 2013 and photographed by Charles W. Melton on 03 and 30 September 2013.  Sound recordings were made on 02 September 2013 by Janet Cunningham and Joe Woodley. 

Potential third US record.  The only previous records of this species for the ABA area are the long staying bird in Patagonia, AZ in 2008-09 and a second bird at nearly this location in Huachuca Canyon in 2009.  This species is essentially a west Mexican endemic. It is regular in central Sonora and is reported to be expanding its range northward so that it now can apparently be found within 30 miles of the US border.

This is a very dull immature which lacks the characteristic black and white steaks at the side of the neck although a hint of them can be seen.  In addition, the rusty tail does not contrast as much with the back as in an adult.  However, Bewick's Wren would have a thinnner bill and a longer eyeline.  Fortunately, the song of this species is diagnostic and the recordings confirm the ID. 

The most recent photo at the bottom shows the bird after completing molt and now the rusty tail and streaks and the rear of the auriculars are more obvious.
