Miscellaneous: White-throated Sparrows

For the last three days, I've had a pair of White-throated Sparrows kicking around the leaves under our bird feeder looking for seeds dropped by the rather messy House Finches that prefer to land directly on the feeder. White-throated Sparrows are not rare but they are by far the least common of the three Zonotrichia genus sparrows we see here in Northern California in the winter months (the others being White-crowned Sparrows and Golden-crowned Sparrows). All three are winter migrants here, usually arriving around October and leaving by April. I always enjoy seeing them. Please excuse the poor photograph, which was taken through the kitchen window.
