I had an unusual bird at my feeders just now with the ususal house sparrows and finches- a partially albino (
Leucistic) house sparrow. It was not as extreme as many cases of leucism, but it still had 2 or 3 tail feathers that were bright white, rather than the drab brown. At a distance, it looked like those were the only feathers in its tail, because they were so bright.
Good Birding
