Margaret, I missed commenting on your photos the other day but I wanted to let you know how much I enjoyed them - the Robin with the worm is a classic and the Towhee is so neat! I see both of those mostly in the winter but I thought I saw a Robin fly over a couple of days ago.
Lin, loved your photos - most of them are ones I never see here and I'd never even heard of the Parula before!
Here are some American White Pelicans flying by but I WAS standing in my backyard when I took the photo, lol! I live right under a major flyway & get to see lots of flocks of migrating birds in the fall & spring
