Female Eastern Bluebird bringing nesting material back to a bird house. NOTE: The same bird house has several male Tree Swallows flying around and sitting on it as if it were theirs.

Both species, bluebirds and tree swallows, are cavity nesters and often use the same type of next boxes. It would seem both have the same idea as to where they want to nest, may be a little competition.
Thank you Ava.
Since she/he is getting nest materail, please consider adding this spotting to the Animal Architecture mission at http://www.projectnoah.org/missions/8082...
