Prominent among a great variety of song-birds and insectivorous birds are the robin, blue bird, cat bird, sparrows, meadow-lark, bobolink, thrushes, chickadee, wrens, brown thrasher, gold finch, cedar wax-wing, flycatchers, nuthatches, flicker (golden-winged woodpecker), downy and hairy woodpeckers, rose-breasted grosbeak, Baltimore oriole, barnswallow, chimney swift, purple martin, purple finch (linnet), vireos and several species of warblers.
Such are the thick-headed shrikes (Pachycephalidae), the caterpillar-eaters (Campephagidae), the flower-peckers (Dicaeidae), and the swallow-flycatchers (Artamidae).
There are a raven (Corvus), a coot (Fulica), the well-known Sandwich island goose (Bernicla sandvicensis), now very commonly domesticated in Europe; and some flycatchers and thrushlike birds.
Of other families which, however, extend their range more or less far into the Australian realm, may be mentioned Otididae, the bustards; Meropidae or bee-eaters; Muscicapidae or flycatchers; Sturnidae or starlings.
The song and insectivorous birds - thrushes, flycatchers, vireos and woodpeckers - of this latitude, are well represented, and the high plateaus (particularly the Pocono plateau) have especial ornithological interest as the tarrying-places, during the migratory seasons, of many species of birds whose natural breeding ground is much farther north.
