Field Marks and
Identifying Characteristics:
On the morning (~ 8:00a) of September 30, 2011, I located a Brown Thrasher scratching in the thick underbrush bordering the east side of the orchard at Lytle Ranch. Later that morning I ran into the Sommerfelds who had just located a Brown Thrasher along the Beaver Dam Wash west of the parking area near the gate into Lytle Ranch. Together we relocated the thrasher along the wash, and later we all went back through the orchard and saw the thrasher adjacent to the orchard. We were rather certain there must be two birds present until later examination of photos proved it was the same thrasher in both locations (based on missing tail feathers).

Medium to large thrasher with a relatively short bill and long tail. Uppersides bright rufous orange from cap to tail, and undersides bright white from chin to undertail coverts. Undersides with prominent thin dark streaking across chest and belly, but not extending to undertail coverts. Wings rufous with two distinct, thin, white wingbars. Legs long and gray. Bill black with grayish lower mandible. Eye with yellow iris and dark pupil.
