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).
Position the bird house far enough away from brush so predators cannot stage an ambush, but close enough to plants so parent birds can easily scout the area. Five to eight feet of distance is sufficient for most bird houses. Similarly, keep bird houses away from popular feeding areas to prevent territorial conflicts between feeding birds and nesting parents. Choose natural colors so the bird house will blend into the surroundings: Browns and dark shades of green are the most suitable choices and will be the most attractive to birds. If desired, decorate the house with natural materials to keep it concealed but still an ornamental focal point in the yard.
