House Sparrows (English Sparrows) are a variety of finch. Identify them by spotting the male. He has a black bib across his chest and a chestnut brown stripe down the back of his neck. Do not mistake this for the chestnut colored cap that marks the Chipping Sparrow.
Native sparrows do not nest in cavities. They are not the sparrows which trouble martins.
English Sparrows will attempt to kill Purple Martin adults and young still in the nest. They will try to take over nesting sites, break eggs and build their nest directly on top of martin nests and nestlings.
