How to Build a Birdhouse for Finches
Creating the best environment for families is not only important for humans, but also for finches. If you want to build a birdhouse for finches, you must create a safe environment offering plenty of finch-friendly resources to help a family of finches thrive. You can offer neighborly assistance, according to The National Audubon Society, by "supplying some of the materials they seek, such as twigs; short lengths of string, yarn, and thread; cotton; hair brushed from a pet; and sphagnum moss. Leave the offerings in a tray or in an onion net bag hung from a tree." Finches are enthusiastic singers that will add plenty of entertainment to a backyard.
Select ¾-inch roughly cut redwood, cedar or even plywood. Rough-cut wood will allow finches to grasp the birdhouse. According to BirdHouses 101, "The ideal Finch birdhouse should have a 6-inch by 6-inch floor, 6-inch inside ceiling and a 1½-inch diameter entrance hole located 4½ inches above the floor and ventilation opening."
Secure with corrosion-resistant screws the right 6-inch panel to the larger back panel. Attach the floor of the birdhouse to the right and back panel. Add the left 6-inch panel to the back panel and the birdhouse floor. Fasten the front panel with a 1½-inch diameter entry hole 4½-inch above the floor of the birdhouse. Before putting the roof on your finch birdhouse, consider attaching hinges to the roof and then secure it to the back panel. A roof with hinges will allow easy access to your finch birdhouse for cleaning purposes. Add shutter hooks to the roof and side panels in order to secure it.
Make sure your finch birdhouse has enough ventilation with ¼-inch drainage holes at each corner of the floor. Drill ½-inch holes at the top of each side panel.
Add a security system to your new finch birdhouse by securing a small piece of wood near the entrance to make it difficult for predatory birds and other animals to access.
Mount the finch birdhouse on to a high metal pole. Choose a location that is cool and away from a birdfeeder.
Attract finches to a new birdhouse by adding a favorite food such as sunflower seeds to a birdfeeder. Fruits such as mulberries and cherries are another appetizing treat for a finch. Plant sunflowers, marigolds, birch trees and zinneas.
