This Russet-backed Swainson's Thrush (Catharus ustulatus [ustulatus group]) was at Paradise Pond in Port Aransas, Nueces county, Texas on April 13, 2013. It has been accepted by the TBRC as belonging to the ustulatus group. This is the only photo I got of the bird, but Ron Hillstrom obtained a few (better) images that formed part of the record. The location and date may seem unlikely for a western taxon, but this subspecies group winters as close as southern Tamaulipas, Mexico -only 345 miles from Port Aransas:
Note the lack of emargination on P6, the primary tip spacing, and rufous tone to the tail/utcs and primary edges:
