The question sounds cold, but sticks in my mind, because a Fox Sparrow is an interesting find, not endangered by any means, but not common either. Certain birders have a sort of pride about stalking and then “pishing” or flushing out the object of their desire, thus validating the life-list item by their mastery of birding techniques. Obviously this would not qualify by any of those standards. (“Pishing” is a birder’s imitation of a commonly heard alarm call–think in particular the Tufted Titmouse.)
The most official criterion, though, is simply that one have a photo. So this one does qualify by that requirement. Reviewers would remark that the bird is obviously dead, so it would probably be marked as illegitimate. See E-bird’s Data Quality Control Page for some more information on the evidence citizen science counts and maps expect.
The location is not totally unexpected (NC mountains), but who says that this bird couldn’t have been a late migrant who decided to stop for a bite to eat around our house, then took mortal offense at his challenging reflection?
So I have no firm answers really. But I am thankful to have witnessed some of God’s beauty manifest in the birds, even in a sad context.
