Characteristics of Ponderosa Pine Snags Used by Cavity - Nesting Birds in Arizona
Abstract:In the Southwest, ponderosa pine (Pinus ponderosa Laws.) snags are important as nest sites for cavity-nesting birds. A study in Arizona found that birds selected snags that were greater than 15 inches in d.b.h. and taller than 75 feet. Preferred snags had more than 40 percent bark cover and had been dead six or more years.
