Breeds commonly throughout most of the USA but absent from the north-west and north-central states, also breeds sparsely in south-east Canada.

Interior populations are migratory wintering in the southern USA, on the east coast resident from Maine southwards.

Casual vagrant north of range.

Introduced to Hawaii.

In the Western Palearctic recorded in Britain, in Cornwall, August 1982 and Essex, May 1988, and at Schiermonnikoog in the Netherlands in October 1988 and another in the Netherlands in March 2001. These birds may have had a captive origin and others seen in Europe are generally considered to relate to escapes including one or two further British reports.

Taxonomy

Subspecies

Wing flashing behaviour^[2]

This is a polytypic species consisting of three subspecies^[1]:

M. p. leucopterus:

South-western Canada to southern Baja California and south-western Mexico (Oaxaca)

M. p. polyglottos:

Eastern Canada to central, eastern and south-eastern US

M. p. orpheus:

Bahamas and Greater Antilles

Habitat

Woodland edges, copses and hedgerows, very common in suburban gardens and also found in many city parks.
In winter, maintains a small territory around patches of fruiting shrubs/trees that it defends from other birds.

Behaviour

As an intelligent and resourceful bird that is at home in a variety of habitats and can coexist with human settlement, this species is not likely to be endangered in any forseeable future.

They have a habit of wing-flashing, which hasn't been entirely explained.^[2]

Diet

These birds forage on the ground or in vegetation and fly down from a perch to capture food. Diet includes insects, berries and seeds.

Breeding

They build a twig nest in a dense shrub or tree.

They aggressively defend the nest and territories from all encroachment, and will attack much larger animals and even humans who come too near.

Vocalisation

The species name is a result of its many and varied vocalizations, and its ability to mimic other bird calls and sounds of many types. Particularly at dawn it produces a veritable concert of songs, often not repeating the same pattern for a considerable period.

This habit of singing longest and loudest at dawn leads some people to resent the Mockingbird, and even attempt to eliminate it from their environments.

 ==Habitat==
-Woodland edges, copses and hedgerows, very common in suburban gardens and also found in many city parks. Mockingbirds have a strong preference for certain trees such as maple, sweetgum, and sycamore. They generally avoid pine trees after the other trees have grown their leaves. Also, they have a particular preference for high places, such as the topmost branches of trees. Mockingbirds are often found in urban and suburban areas, where they perch on telephone poles, streetlights, or high points on buildings.

 ==Behaviour==
-These birds forage on the ground or in vegetation; they also fly down from a perch to capture food. They mainly eat insects, berries and seeds. While foraging they frequently spread their wings in a peculiar two-step motion to display the white patches. The Northern Mockingbird builds a twig nest in a dense shrub or tree, which it aggressively defends against other birds and animals, including humans. When a predator is persistent, Mockingbirds from neighboring territories, summoned by a distinct call, may join the attack. Other birds may gather to watch as the Mockingbirds harass the intruder.
+As an intelligent and resourceful bird that is at home in a variety of habitats and can coexist with human settlement, this species is not likely to be endangered in any forseeable future.
-While singing on a high perch they will often bolt several feet into the air in a looping motion, with wings outstretched to display their white underside, then land back on the perch without breaking a note. This action serves as a territorial display.
+They have a habit of wing-flashing, which hasn't been entirely explained.<sup>[[#References|[2]]]</sup>

+====Breeding====
+They build a twig nest in a dense shrub or tree.<br />
-The Northern Mockingbird, in addition to being a good mimic, is also one of the loudest and most constantly vocal of birds. It often sings through the night, especially unmated males, or when the moon is full. It sings year-round except sometimes for the late-summer moulting season. Individual males have repertoires of 50 to 200 songs; females sing as well, but more quietly and less often than males. Mockingbirds usually sing the loudest in the twilight of the early morning when the sun is on the horizon.
+They aggressively defend the nest and territories from all encroachment, and will attack much larger animals and even humans who come too near.
+====Vocalisation====
+The species name is a result of its many and varied vocalizations, and its ability to mimic other bird calls and sounds of many types.  Particularly at dawn it produces a veritable concert of songs, often not repeating the same pattern for a considerable period.
-In addition to its well-known song, the Northern Mockingbird utilizes a variety of calls to communicate specific information. As with its song, these calls are among some of the louder sounds produced by birds of its size. Mockingbirds make a harsh, raspy noise when chasing other birds out of their territory. A similar but distinct call is used when defending against predators like a hawk or falcon. Other calls include a wheezing noise, a "chuck" note, and a very piercing series of notes "high low" repeated twice.
+This habit of singing longest and loudest at dawn leads some people to resent the Mockingbird, and even attempt to eliminate it from their environments.
