Brewer's Sparrow
Spizella breweri
The Brewer's Sparrow (Spizella breweri) breeds in the northwestern U.S. as well as parts of Canada and Alaska. The species winters commonly in grass and brush habitats in the southwestern U.S. and Mexico. At times it can be found on the wintering grounds in very large flocks. The photo shown here was taken from a vehicle window with a hand-held Canon T-90 and a FD 400 mm F 4.5 lens with a 1.4X extender on Fuji Sensia 100 in Jeff Davis Co., Texas in December, 1995. The below photo, which shows the characteristic dark lines on the crown, was taken in Las Cruces, Dona Ana Co., New Mexico in December, 1989, with the same equipment but with Kodachrome 200.
The singing Brewer's Sparrow in the next 6 images below was at the Pawnee National Grasslands, Weld Co., Colorado, in June, 2007. These are digital shots taken with a Canon EOS 1D Mark II and EF 600mm F/4 L IS lens and 2X extender.
The Brewer's Sparrows in the next 3 images were in Catalina, Pima Co., Arizona, in March, 2009. These images were shot with a Canon EOS 1D Mark III and and EF 800mm F/5.6 L IS lens. These were wintering birds which had not yet departed for the breeding range.
