Clean the house seasonally or whenever a family of birds vacates the premises: Remove all nesting debris and rinse the house with a sanitizing solution of one part bleach and nine parts water. Rinse the house again with clear water, and allow it to air dry thoroughly before storing it for the winter or repositioning it for new tenants. Nesting birds face many different hazards, but there are easy ways to make any bird house design safer and more attractive to bird families. Building a bird house may seem like an easy project, but there is much more to an attractive, bird_friendly house than a wooden box with an entrance hole. Before you build a bird house, you need to understand what nesting birds need and how best to meet those needs with the house you construct.
Dead trees, or snags, are valuable to a wide variety of wildlife. Unfortunately, many people assume snags are of no value and routinely cut them down. In some places, this practice has caused cavity_nesting bird and mammal populations to decline. Though nest boxes may provide alternate nesting sites for some cavity_nesting birds, they are not suitable replacements for dead trees. Here's why: Snags provide homes for woodpeckers. Woodpeckers use snags for drumming, nesting, roosting, and feeding. Woodpeckers hammer their bills against the resonating surface of dead tree trunks to make a loud drumming sound; this is their courtship and territorial "song."
