This White-throated Sparrow (Zonotrichia albicollis) was feasting on the abundant sumac berries when I spotted him on Tuesday at Occoquan Bay National Wildlife Refuge. In recent weeks I have repeatedly seen bluebirds in this patch of sumac and I always check it now whenever I visit this location.
I see White-throated Sparrows quite often during the winter months, but this was this first time I have seen them in this field. Normally I spot them when they are poking about in the undergrowth of bushes and other vegetation.

Looks like he found a great place to snack.
A number of species have been feeding in that patch of sumac, especially bluebirds. I’m guessing that any available berries are welcome at this point in the winter.
