List of birds of Pennsylvania
This list of birds of Pennsylvania includes species documented in the U.S. state of Pennsylvania and accepted by the Pennsylvania Ornithological Records Committee (PORC). As of July 2012, there were 420 species on the official list. Of them, 90 are classified as accidental, 36 are classed as casual, six have been introduced to North America, two are known to be extinct and another might be, and two have been extirpated. An additional nine species are classed as provisional; eight of them are also classed as accidental. Between when the official list was published in 2012 and June 2018, 11 more species have been accepted by the PORC, yielding a state list of 440 including the provisional species. Another five species have been documented in the state and are also included in this list, though their reports are pending with the PORC.
This list is presented in the taxonomic sequence of the Check-list of North American Birds, 7th edition through the 59th Supplement, published by the American Ornithological Society (AOS). Common and scientific names are also those of the Check-list.
Unless otherwise noted, all species listed below are considered to occur regularly in Pennsylvania as permanent residents, summer or winter visitors, or migrants. These tags are used to annotate some species:
- (A) Accidental – Species with three or fewer records in the past ten years per the PORC
- (C) Casual – Species with four to seven records in the last ten years per the PORC
- (P) Provisional – Species accepted by the PORC with only sight records
- (I) Introduced – Species established in North America as a result of human action
- (X) Extinct – Recent species that no longer exist
- (Ex) Extirpated – Species which no longer occur in Pennsylvania but are found elsewhere

They have stout, longish bills and webbed feet. Terns are a group of generally medium to large seabirds typically with grey or white plumage, often with black markings on the head. Most terns hunt fish by diving but some pick insects off the surface of fresh water. Terns are generally long-lived birds, with several species known to live in excess of 30 years. Skimmers are a small family of tropical tern-like birds. They have an elongated lower mandible which they use to feed by flying low over the water surface and skimming the water for small fish.

- Yellow-billed loon, Gavia adamsii (A)
The storm-petrels are the smallest seabirds, relatives of the petrels, feeding on planktonic crustaceans and small fish picked from the surface, typically while hovering. The flight is fluttering and sometimes bat-like. Until 2018, this family's three species were included with the other storm-petrels in family Hydrobatidae.
Though the members of this family are similar in many respects to the southern storm-petrels, including their general appearance and habits, there are enough genetic differences to warrant their placement in a separate family.

Frigatebirds are large seabirds usually found over tropical oceans. They are large, black, or black-and-white, with long wings and deeply forked tails. The males have colored inflatable throat pouches. They do not swim or walk and cannot take off from a flat surface. Having the largest wingspan-to-body-weight ratio of any bird, they are essentially aerial, able to stay aloft for more than a week.

- Northern wheatear, Oenanthe oenanthe (A)
The thrushes are a group of passerine birds that occur mainly but not exclusively in the Old World. They are plump, soft plumaged, small to medium-sized insectivores or sometimes omnivores, often feeding on the ground. Many have attractive songs.

Mockingbirds and thrashers
The mimids are a family of passerine birds which includes thrashers, mockingbirds, tremblers, and the New World catbirds. These birds are notable for their vocalization, especially their remarkable ability to mimic a wide variety of birds and other sounds heard outdoors. The species tend towards dull grays and browns in their appearance.

Starlings and mynas are small to medium-sized Old World passerine birds with strong feet. Their flight is strong and direct and most are very gregarious. Their preferred habitat is fairly open country, and they eat insects and fruit. The plumage of several species is dark with a metallic sheen.
- European starling, Sturnus vulgaris (I)
The waxwings are a group of passerine birds with soft silky plumage and unique red tips to some of the wing feathers. In the Bohemian and cedar waxwings, these tips look like sealing wax and give the group its name. These are arboreal birds of northern forests. They live on insects in summer and berries in winter.
Old World sparrows
Old World sparrows are small passerine birds. In general, sparrows tend to be small plump brownish or grayish birds with short tails and short powerful beaks. Sparrows are seed eaters, but they also consume small insects.
- House sparrow, Passer domesticus (I)
Wagtails and pipits
Motacillidae is a family of small passerine birds with medium to long tails. They include the wagtails, longclaws, and pipits. They are slender ground-feeding insectivores of open country.
- American pipit, Anthus rubescens
Finches are seed-eating passerine birds that are small to moderately large and have a strong beak, usually conical and in some species very large. All have twelve tail feathers and nine primaries. These birds have a bouncing flight with alternating bouts of flapping and gliding on closed wings, and most sing well.

Longspurs and snow buntings
The Calcariidae are a group of passerine birds that were traditionally grouped with the New World sparrows, but differ in a number of respects and are usually found in open grassy areas.
New world sparrows
Until 2017, these species were considered part of the family Emberizidae. Most of the species are known as sparrows, but these birds are not closely related to the Old World sparrows which are in the family Passeridae. Many of these have distinctive head patterns.

The icterids are a group of small to medium-sized, often colorful passerine birds restricted to the New World and include the grackles, New World blackbirds, and New World orioles. Most species have black as a predominant plumage color which is often enlivened by yellow, orange, or red.
