Everything about Turkeys totally explained
See Turkey for the country and Turkey (disambiguation) for other uses
A
turkey is either of two
extant species of large
birds in the
genus Meleagris native to
North America. Turkeys are classed in the
order Galliformes. Within this family they're placed on one branch with
Tetraonidae. 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 than the male (the tom), and much less colorful. With wingspans of 1.5–1.8
meters (almost 6
feet), the turkeys are by far the largest birds in the open forests in which they live, and are rarely mistaken for any other species.
Naming
When Europeans first encountered turkeys in the Americas they incorrectly identified the birds as a type of
guineafowl (
Numida meleagris), also known as a turkey-cock from its importation to Central Europe through
Turkey, and the name of that country stuck as the name of the bird. The confusion is also reflected in the scientific name:
meleagris is
Greek for guinea-fowl.
The
names for M. gallopavo in other languages also frequently reflect its exotic origins, seen from an Old World viewpoint, and add to the confusion about where turkeys actually came from. The many references to
India seen in common names go back to a combination of two factors: first, the genuine belief that the newly-discovered
Americas were in fact a part of
Asia, and second, the tendency during that time to attribute exotic animals and foods to a place that symbolized far-off, exotic lands. The latter is reflected in terms like "
Muscovy Duck" (which is from South America, not
Muscovy). This was a major reason why the name "turkey-cock" stuck to
Meleagris rather than to the guinea fowl (
Numida meleagris): the
Ottoman Empire represented the exotic East.
The name given to a group of Turkeys is a
rafter, although they're sometimes incorrectly referred to as a gobble or flock.
Several other birds which are sometimes called "turkeys" are not particularly closely related: the
Australian brush-turkey is a
megapode, and the bird sometimes known as the "Australian turkey" is in fact the
Australian Bustard, a
gruiform. The bird sometimes called a Water Turkey is actually an
Anhinga (
Anhinga rufa)
Fossil turkeys
Many turkeys have been described from
fossils. The Meleagrididae are known from the Early
Miocene (c. 23
mya) onwards, with the
extinct genera Rhegminornis (Early Miocene of Bell, U.S.) and
Proagriocharis (Kimball Late Miocene/Early
Pliocene of Lime Creek, U.S.). The former is probably a basal turkey, the other a more contemporary bird not very similar to known turkeys; both were much smaller birds. A turkey fossil not assignable to genus but similar to
Meleagris is known from the Late Miocene of
Westmoreland County, Virginia.
In the modern genus
Meleagris, a considerable number of species have been described, as turkey fossils are robust, fairly often found, and turkeys show much variation among individuals. Many of these supposed fossilized species are now considered
junior synonyms. One, the well-documented
California Turkey Meleagris californica, became extinct recently enough to have been hunted by early human settlers.
though its actual demise is more probably attributable to
climate change at the end of the
last ice age. The modern species and the California Turkey seem to have diverged approximately one million years ago.
Turkeys known only from fossils
- Meleagris sp. (Early Pliocene of Bone Valley, U.S.)
- Meleagris sp. (Late Pliocene of Macasphalt Shell Pit, U.S.)
- Meleagris californica (Late Pleistocene of SW U.S.) - formerly Parapavo/Pavo
- Meleagris crassipes (Late Pleistocene of SW North America)
Turkeys have been considered by many authorities to be of their own family, the
Meleagrididae but a recent genomic analyses of a
retrotransposon marker groups turkeys in the family
Phasianidae.
Flight
While the large domestic turkey is generally unable to fly, the smaller wild turkey can fly to several meters high. This is usually enough to perch in the branches of trees, however, it's an ineffective method of transportation. Turkey poults (chicks) are unable to fly for the first two weeks after they hatch.
