Hi everyone, I have only seen Bluebirds and Tree Swallows near this next box, but the single egg here sure looks like a house sparrow's. Any thoughts? http://www.flickr.com/photos/29085111@N00/4596788148/ The nest is Tree Swallow. If you look close at the egg it definately has verigation like a house sparrow's but it is very light. The hole is an elongated 1-3/8" x 2-1/4"long. Regards, John Stuckert Pewaukee, WI #################### You received this email because you are subscribed to the Wisconsin Birding Network (Wisbirdn).
