Most bobcats are found in the wilder parts of the state. The bobcat was declared a game animal and given total protection here in 1970. The male's breast in spring is the most vivid. The robin's call is a series of chirps, rising and falling. Young robins often fall out of their nests and die, but robins produce so many young each year that the population remains fairly stable.
Nests are of mud and grass, in a tree or on a ledge.
These nests are protected, as are those of most songbirds, by federal law. Once a common sight in the Pennsylvania countryside, the bluebird has dwindled in the past half-century. Among the many reasons for its decline are loss of tree-cavity nesting spots, and competition for the few sites from house sparrows and starlings. Many outdoorsmen erect suitable bluebird nest boxes in an effort to bring back this lovely little bird with the voracious appetite for insects. Boxes must be the exact size to let bluebirds in and keep competitors out.
