In early spring, hang a charming, decorative hummingbird house! Habits of the hummingbird include males migrating early to "stake" their territory out, and they can attract up to 25 females! While there is no guarantee they will use this decorative house (there are no guarantees with any birdhouse), they are a very attractive addition to any backyard or garden. If a nest is built near you, hatchlings will return the next year. Nests are the size of a penny. Eggs (2) are the size of a Tic Tac. Clean out the ornamental house each winter with an old bottle brush and take inside. Each house comes with an instruction card. Good luck!
