Avoid bird houses made of metal. Metal houses will become miniature ovens in summer heat, and reflective metals are highly visible to predators. The house can have metal guards or trim over a different material, however, such as a metal cover to fix an entrance hole to the proper size if needed. Healthy Houses: Bird houses can become crowded as nestlings grow, giving diseases and mites greater opportunities to spread to young birds. A safe bird house is one that takes into account the health of the birds.
Seed_eating birds that can be attracted to feeders include pine siskins, sparrows, grosbeaks, redpolls, and crossbills. These species also eat suet, but seeds will attract them to your feeder. Unsalted sunflower seeds, thistle seeds, raw crushed peanuts, millet, scratch feed, various wild grains, and canary seeds are welcomed. Commercial wild bird seed mixes can be used, but they often contain filler seeds that are not eaten by many species. Often, you can mix your own "wild bird food" more economically. Seeds can be purchased from local feed, variety, and pet stores, or ordered from catalogs. When you first start your feeder, experiment with various seeds and find out which are preferred by the birds in your area.
