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).
If you are an confident woodworker with some building experience, you may even feel comfortable designing your own bird house with the information you've learned about what nesting birds want. If you are a novice, however, building a bird house from scratch may seem too intimidating or ambitious, even with detailed plans. In that case, you may want to consider using a bird house kit with pre_cut pieces to assemble. Another option is to start with a simple bird house and make modifications to the design to make it more bird_friendly to suit the species you hope will take up residence.
