Common birds include boreal owl, great horned owl, blue jay, white-throated sparrow and evening grosbeak. Lakes contain brook char, lake trout, northern pike, perch, and walleye.
Wildlife use the tree for food and nesting. Porcupines eat the inner bark, snowshoe hares feeds on tamarack seedlings, and red squirrels eat the seeds. Birds that frequent tamaracks during the summer include the white-throated sparrow, song sparrow, veery, common yellow throat, and Nashville warbler.
The bird species he studied include the Eurasian blackbird, snow goose, black-capped chickadee, boreal chickadee, alpine accentor, white-throated sparrow, Bicknell's thrush , ovenbird, pileated woodpecker. In mammals, his research has focused particularly on the American marten and the Siberian flying squirrel.
Adults are long and have black and white stripes on their head, a gray face, brown streaked upper parts and a long tail. The wings are brown with bars and the underparts are gray. Their bill is pink or yellow. They are similar in appearance to the white-throated sparrow, but do not have the white throat markings or yellow lores.

The golden-crowned sparrow is one of five species in the genus "Zonotrichia", a group of large American sparrows. It has no subspecies. It is a sister species with, and very closely related to, the white-crowned sparrow; studies of mitochondrial DNA show the two evolved into separate species very recently in geologic time. The white-throated sparrow is a slightly more distant relative. Hybridization with both white-crowned and white-throated sparrows has been reported.
Sugar maple, yellow birch, American beech, and White Ash are the common key indicator tree and shrub species in the Northern Hardwood Forest. Other species include eastern hemlock and eastern white pine. Herb and heath species include wintergreen, wild sarsaparilla, and wood sorrel. Birds and animals common to the Northern Hardwood Forest include the black-capped chickadee, white-throated sparrow, cedar waxwing, porcupine, snowshoe hare, white-tailed deer, and American Red Squirrel.
The fruit are an important food for many birds, including Florida duck, American black duck, mourning dove, ruffed grouse, bobwhite quail, wild turkey, northern flicker, sapsuckers, cedar waxwing, eastern bluebird, American robin, gray catbird, northern mockingbird, and white-throated sparrow. Mammals that eat the fruit include nine-banded armadillo, American black bear, gray fox, raccoon and skunks. The foliage and twigs are browsed by white-tailed deer.
More than 300 species of birds have their nesting grounds in the taiga. Siberian thrush, white-throated sparrow, and black-throated green warbler migrate to this habitat to take advantage of the long summer days and abundance of insects found around the numerous bogs and lakes. Of the 300 species of birds that summer in the taiga only 30 stay for the winter. These are either carrion-feeding or large raptors that can take live mammal prey, including golden eagle, rough-legged buzzard (also known as the rough-legged hawk), and raven, or else seed-eating birds, including several species of grouse and crossbills.
Although its distinctive crown patches allow for easy identification of the adult golden-crowned sparrow in breeding plumage, an immature or non-breeding bird might be mistaken for a white-crowned or white-throated sparrow. It is distinguished from the former by its crown pattern and dusky (rather than pale pink or yellowish) bill, and from the latter by its larger size, plain throat, and lack of a buff-colored central crown stripe. A young or non-breeding bird may also resemble a female house sparrow, but can be distinguished by its larger size, darker plumage, longer tail and (usually) some amount of dull yellow feathering on its forehead.
Bird watchers have observed over 200 species of birds in the park, including the great blue heron, northern harrier, white-throated sparrow and highly sensitive species which are rare as breeding birds in Pennsylvania such as northern goshawk and yellow-bellied flycatcher. The state park and forest are part of the larger Pennsylvania Important Bird Area (IBA) #42, which encompasses . The Pennsylvania Audubon Society has designated the IBA as a globally important habitats for the conservation of bird populations. The IBA is home to Swainson's thrush and ruffed grouse, the state bird of Pennsylvania. Other notable passerine species found in the park and IBA include blue-headed and red-eyed vireos, Acadian and least flycatchers. Breeding warblers in the park include both northern and Louisiana waterthrushes, as well as Blackburnian, black-throated blue, black-throated green, Canada, magnolia, mourning, Nashville, and yellow-rumped.
On the other hand, mating between individuals of genotypes that are too similar allows for the accumulation of harmful recessive alleles, which can decrease fitness. Such mating between genetically similar individuals is termed inbreeding which can result in the emergence of autosomal recessive diseases. Moreover, assortative mating for aggression in birds can lead to inadequate parental care. An alternate strategy can be disassortative mating, in which one individual is aggressive and guards the nest site while the other individual is more nurturing and fosters the young. This division of labor increases the chances of survival of the offspring. A classic example of this is in the case of the white-throated sparrow ("Zonotrichia albicollis"). This bird exhibits two color morphs – white striped and tan striped. In both genders, the white striped birds are more aggressive and territorial whereas tan striped birds are more engaged in providing parental care to their offspring. Therefore, disassortative mating in these birds allows for an efficient division of labor in terms of raising and protecting their offspring.
