Audubon Backyard Birds FAQ

Audubon has just posted a new backyard bird FAQ page. Perhaps a good resource for a bird club or anyone else who gets frequent emails about the following:

--Why does a male cardinal continuously bang against the windows of our house?
--What kind of hawk is this in my backyard? Should I stop feeding the birds?
--Can you recommend a squirrel-proof feeder?
--When is the best time to hang a nesting box? How big should it be?
--I found a baby bird out of its nest and hopping around our backyard. What should I do?
-- An ugly, bald bird just showed up at my feeder. It resembles a cardinal but it has a blue head. What is it?
--There is a white bird in my yard. Is it an albino or some kind of rare species?
--I live in Massachusetts and saw a small black and white woodpecker in my backyard. Could it be a baby Ivory-billed Woodpecker?

The answers to these questions are online here.
