Originally posted by Deep Dene Steve Hirundo rustica is our only swallow - you seem to be spoilt for choice in the States. We also have house martins and sand martins, which are similar birds but spend our winters further south, down in South Africa I think, whereas our swallows just go to central Africa. The only other bird of this type is the swift, which from fledging to maturity can spend two or more years on the wing, without ever perching. Amazingly, I have a few shots of them but they are not sharp and no way would I make them public. I am trying to concentrate my efforts on more static stuff at the moment - bricks and concrete, dozy insects, friends and family who don't yet realise what damage I can do to their self-image.
We can attract purple martins here, but they're very picky. Our neighbor used to have a martin house, but he's too old to maintain it and the family took it down. We do have chimney swifts, I forgot about those. They unfortunately try to nest in chimneys and this can be deadly. One got stuck in our furnace intake a few years ago. Twice, to be accurate. After that we had the chimney repaired with a new liner and exterior bricks (which looks great). The swifts are cool birds, and will perch on the power lines in the yard. I think your swifts are bigger, ours is the size of a swallow and uniform brown. Of course, when I had the injured one in my hand I never thought to have my wife take a picture, we were both too concerned with the bird.
No question, this is a good area along the river. I've noticed the recovery of a few species as people plant more friendly foliage - fruits like crab apples and hawthornes for the waxwings, and native plants for the little native sparrows etc. I have lots of pictures on my Flickr site, though you'll have to look for the proper albums.
If you want to have fun with your family, get a fisheye lens!
