Mimus polyglottos
TAXONOMY
Turdus polyglottos Linnaeus, 1758, Carolina. Three subspecies.
OTHER COMMON NAMES
English: Mockingbird; mocking thrush; French: Moqueur
polyglotte; German: Spottdrossel; Spanish: Sinsonte Comъn.
PHYSICAL CHARACTERISTICS
9–10 in (23–25.5 cm); 1.3–2 oz (36.2–55.7 g). Plumage generally
gray, wings and tail darker gray with pale edgings to
coverts, white flash on primaries and white outer rectrices. Eye
yellow, bill black with paler base, legs dusky. Juvenile with obscure
spots on chest.
DISTRIBUTION
M. p. polyglottos: eastern North America from east Nebraska to
Nova Scotia, south to east Texas and Florida; M. p. leucopterus:
western North America from northwest Nebraska and west
Texas to the Pacific coast, south throughout Mexico to the
Isthmus of Tehuantepec; M. p. orpheus: Bahama Islands,
Greater Antilles east to Virgin Is. Vagrant to Great Britain; introduced
to Hawaiian Islands.
HABITAT
Open bushland, well-vegetated suburban areas, abandoned
farmland, orchards.
BEHAVIOR
Self-assured and conspicuous. Spends most of its time on the
ground or in low vegetation. During breeding season very aggressive,
not hesitating to attack predators such as cats and
crows. Song is a loud, very varied series of strong musical
notes, frequently including imitations of other species, sometimes
repeated over and over; often sings at night, especially in
urban settings.
FEEDING ECOLOGY AND DIET
Food includes both animal (mostly invertebrate, but including
small lizards) and vegetable matter (especially berries).
REPRODUCTIVE BIOLOGY
Nest is an open cup, the base of dead twigs, built mainly by
the male, the lining of grasses added by the female, usually less
than 10 ft (3 m) from the ground in shrubs. Eggs two to six,
base-color bluish or greenish white or somewhat darker, with
brownish markings. Incubation by female alone, 12–13 days.
Fed by both parents, fledging period 12–15days. Two or three
broods per year.
CONSERVATION STATUS
Not threatened. Over most of its range common or abundant.
Has adapted well to human situations and probably expanded
as forest was cleared; has benefited from plantings of such
species as multiflora roses.
SIGNIFICANCE TO HUMANS
Little economic significance. A popular species, widely celebrated
in literature and the state bird of Texas, Arkansas, Mississippi,
Florida, and Tennessee.
