We're oftentimes overwhelmed with the idea that the natural environment is in a state of seemingly unstoppable decline. One of the greatest causes is destruction of natural habitat. And, loss of nesting spaces for birds is a prime example of a major consequence. This site leads the visitor to a very simple solution that allows one to act locally while thinking globally. The Birdhouse Network website from the Cornell Lab of Ornithology offers all sorts of good information on bird houses, including construction plans to where to put the house(s) once finished. A great resource on the site for those of us who are backyard birders is the Bird Bios section. This area gives short snippets on common backyard birds like the Black-capped Chickadee to the House Sparrow. If you build it, they will come!
