Brown Thrasher
(Toxostoma rufum)
is a bird of the eastern U.S. and is casual in the west.
There are one or two birds reported in AZ almost every
year. There has been one seen at
Boyce Thompson Arboretum
(where the first two photos were made) for many
winters. The third and fourth images were taken at the
Gilbert Water Ranch in
December 2011.
