To build the best bird house, you first need to learn what cavity_nesting birds are frequent visitors in your region. These are the birds most likely to investigate your house, and when you keep their needs in mind, you can build a bird house to invite them to become more permanent residents. Start With a Plan: A bird house doesn't need to be complicated, but if you haven't built one before, it is best to start with a tried_and_true plan. There are many free bird house plans available online with styles and designs suitable for beginning woodworkers to experienced architects, or you can buy a book of bird house plans for a hard copy reference.
Although both species have been found in Alaska, only Starlings have become established, as yet. Starling nests have been recorded in central and southeastern Alaska, and the species is regularly observed in southcoastal and western Alaska. Starlings and House Sparrows will use nest boxes with entrance holes larger than 1ƽ inches in diameter. Keep a careful watch on your waterfowl, owl, woodpecker, and bluebird nest boxes to be sure that Starlings and House Sparrows do not invade them. (Please report any observation of Starlings or House Sparrows to Alaska Wildlife Observations, c/o University of Alaska Museum, 907 Yukon Drive, Fairbanks, AK 99701).
