Passerine in flight quiz answers...

Many thanks to those who played along with the photo quiz. The photos are below. Five of six images recieved a correct response. The answers:

1. Yellow-rumped Warbler
2. Orchard Oriole
3. Chestnut-sided Warbler
4.  ???
5. Ruby-crowned Kinglet
6. Purple Finch


As perhaps expected, photo #4 is the one that has yet to receive a correct answer. Any new guesses?
