This list of birds of Maryland includes species credibly documented in the U.S. state of Maryland and accepted by the Maryland / District of Columbia Records Committee (MRC) of the Maryland Ornithological Society as of 2022. There are 456 species included in the official list. Eight additional species of questionable origin and two of exotic origin per the MRC are also included in this page. Of the 460 species, 121 are rare anywhere in the state, 64 are rare in some part of the state, six have been introduced to North America, two are extinct, and two have been extirpated. Two additional accidental species have been added from different sources.

This list is presented in the taxonomic sequence of the Check-list of North and Middle American Birds, 7th edition through the 62nd Supplement, published by the American Ornithological Society (AOS). Common and scientific names are also those of the Check-list, except that the common names of families are from the Clements taxonomy because the AOS list does not include them.

Unless otherwise noted, all species listed below are considered to occur regularly in Maryland as permanent residents, summer or winter visitors, or migrants. The following tags are used to annotate some species:

• (R) Rare - "Reviewable if found anywhere in Maryland" per the MRC
• (R*) Rare (limited area) - "Reviewable if found in certain specified ranges in Maryland" per the MRC
• (QO) Questionable origin - "Accepted species that may or may not be wild or naturally occurring" per the MRC
• (EO) Exotic origin - "Accepted species whose natural history precludes wild or natural occurrence" per the MRC
• (I) Introduced - a species that has been introduced to North America by the actions of humans, either directly or indirectly
• (Xt) Extinct - a recent species that no longer exists
• (Xp) Extirpated wild - a natural or wild species which is no longer found in Maryland, but still exists elsewhere
• (Xx) Extirpated exotic - a formerly established introduced species which no longer occurs in Maryland

Order: Galliformes   Family: Phasianidae

Phasianidae consists of the pheasants and their allies. These are terrestrial species, variable in size but generally plump with broad relatively short wings. Many species are gamebirds or have been domesticated as a food source for humans. Turkeys have a distinctive fleshy wattle that hangs from the underside of the beak and a fleshy protuberance that hangs from the top of its beak called a snood. As with many galliform species, the female (the hen) is smaller and much less colorful than the male (the tom). With wingspans of 1.5–1.8 metres (4.9–5.9 ft), the turkeys are the largest birds in the open forests in which they live and are rarely mistaken for any other species. Grouse inhabit temperate and subarctic regions of the Northern Hemisphere. In all of Maryland's species, males are polygamous and have elaborate courtship displays. These heavily built birds have legs feathered to the toes. Most species are year-round residents and do not migrate. Four species of Phasianidae have been recorded in Maryland.

• Wild turkey, Meleagris gallopavo
• Ruffed grouse, Bonasa umbellus (R*)

• American flamingo, Phoenicopterus ruber (R)

Order: Podicipediformes   Family: Podicipedidae

• Chuck-will's-widow, Antrostomus carolinensis
• Eastern whip-poor-will, Antrostomus vociferus

Order: Apodiformes   Family: Apodidae

The swifts are small birds which spend the majority of their lives flying. These birds have very short legs and never settle voluntarily on the ground, perching instead only on vertical surfaces. Many swifts have long swept-back wings which resemble a crescent or boomerang. One species has been recorded in Maryland.

• Chimney swift, Chaetura pelagica

Order: Apodiformes   Family: Trochilidae

Hummingbirds are small birds capable of hovering in mid-air due to the rapid flapping of their wings. They are the only birds that can fly backwards. Seven species have been recorded in Maryland.

• Limpkin, Aramus guarauna (R)

Order: Gruiformes   Family: Gruidae

The majority of these species eat small invertebrates picked out of the mud or soil. Different lengths of legs and bills enable multiple species to feed in the same habitat, particularly on the coast, without direct competition for food.

Order: Gaviiformes   Family: Gaviidae

Loons are aquatic birds that are the size of a large duck, to which they are unrelated. Their plumage is largely gray or black, and they have spear-shaped bills.

Order: Procellariiformes   Family: Oceanitidae

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. Two species have been recorded in Maryland.

• Wilson's storm-petrel, Oceanites oceanicus (R*)
• White-faced storm-petrel, Pelagodroma marina (R)

Order: Procellariiformes   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. Two species have been recorded in Maryland.

• Leach's storm-petrel, Hydrobates leucorhous (R*)
• Band-rumped storm-petrel, Hydrobates castro (R)

Order: Procellariiformes   Family: Procellariidae

• Black vulture, Coragyps atratus
• Turkey vulture, Cathartes aura

Order: Accipitriformes   Family: Pandionidae

The Osprey is a medium-large fish-eating bird of prey or raptor. It is widely distributed because it tolerates a wide variety of habitats, nesting in any location that is near a body of water and provides an adequate food supply. It is the only member of its family.
