Took these earlier today (Wednesday, 2012.04.25). The Brown Thrasher (Toxostoma rufum, BRTH) started appearing on that suet feeder a couple days ago. This is a new behavior, new feeding station for ANY of the Thrashers. Best first guess is the Thrasher has noticed the Gray Catbirds at that same feeder. And, no, the image is not cockeyed. That feeder normally sits very horizontally aligned. The word "toad" comes to mind. :))
Both the male and female Eastern Towhee (Pipilo erythrophthalmus, EATO), but moreso the male, have been hitting the food hard the last couple days. Running theme out in the yard is that the adult birds are looking "frazzled". Any second now I expect the latest fledglings to start appearing in hot pursuit of the parents.
