The Eastern Meadowlark, Sturnella magna, is a medium-sized icterid bird, very similar in appearance to the Western Meadowlark. Carl Linnaeus (Latinized as Carolus Linnaeus, also known after his ennoblement as, May 23 new style (13 May old style 1707 who laid the foundations for In Scientific nomenclature, synonyms are different Scientific names used for a single Taxon.

Birds ( class Aves) are bipedal endothermic ( Warm-blooded) Vertebrate animals that lay eggs. The Western Meadowlark ( Sturnella neglecta) is a medium-sized blackbird, very similar in appearance to the Eastern Meadowlark. It occurs from eastern North America to South America, where is is also most widespread in the east. South America is a Continent of the Americas, situated entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a

Description

Adults have yellow underparts with a black "V" on the breast and white flanks with black streaks. The upperparts are mainly brown with black streaks. They have a long pointed bill; the head is striped with light brown and black.

The song of this bird is simpler and not warbled like that of the Western Meadowlark; their ranges overlap across central North America. In the field, the song is often be the easiest way to tell the two species apart. In Biology, a species is one of the basic units of Biological classification and a Taxonomic rank.

Taxonomy

The unrelated Yellow-throated Longclaw (Macronyx croceus) from Africa looks identical at first glance.

This species was first described by Linnaeus in his 1758 Systema naturae as Alauda magna[1]. In Biology, a species is one of the basic units of Biological classification and a Taxonomic rank. Carl Linnaeus (Latinized as Carolus Linnaeus, also known after his ennoblement as, May 23 new style (13 May old style 1707 who laid the foundations for The book Systema Naturae was one of the major works of the Swedish doctor of medicine Carolus Linnaeus. The type locality is mistakenly given as "America, Africa"

Linnaeus' error is explained by two facts: first, he did not distinguish between the Eastern and Western meadowlarks. In biology a type is that which fixes a name to a Taxon. Depending on the nomenclature code which is applied to the organism in question a type may be a specimen The peculiar belief that this bird also occurred in Africa is due to confusion of the yellow-breasted meadowlarks with certain longclaws (Macronyx), quite unrelated African songbirds. The longclaws are a genus of small Passerine Birds with long tails which they wag frequently SongBird is a Dutch Record label owned by Tijs Verwest and Arny Bink Specifically the Cape Longclaw (M. The Cape Longclaw or Orange-throated Longclaw, Macronyx capensis, is a Passerine Bird in the family Motacillidae, which comprises capensis) and the Yellow-throated Longclaw (M. UserPolbot. -->The Yellow-throated Longclaw ( Macronyx croceus) is a species of Bird in the Motacillidae croceus) share similar habitat and habits, explaining the long hind toe; their plumage pattern however is all but identical, a striking example of convergent evolution. Convergent evolution describes the acquisition of the same biological trait in unrelated lineages As this exact pattern provides no obvious adaptive benefit compared to that of other meadowlarks and longspurs, it seems to have arisen twice by sheer chance. An adaptation is a characteristic of an Organism that has been favored by Natural selection and

Linnaeus recognized his error less than a decade later, separating the longclaws from their meadowlark look-alikes.

The scientific name Sturnella magna is Latin for, rather confusingly, "large little starling", the generic name having being given due to the meadowlarks' behavior being similar to starlings. Latin ( lingua Latīna, laˈtiːna is an Italic language, historically spoken in Latium and Ancient Rome. Starlings are small to medium-sized Passerine Birds in the family Sturnidae.

Ecology

Their breeding habitat is grasslands and prairie, also pastures and hay fields. Prairie, from the French prairie ("meadow" "grassland" "pasture" refers to an area of land of low topographic relief that historically Hay is a generic term for grass or Legumes that have been cut dried and stored for use as animal feed, particularly for grazing animals like This species is a permanent resident throughout much of its range, though most northern birds migrate southwards in winter[2]. Bird migration refers to the regular seasonal journeys undertaken by many species of Birds Bird movements include those made in response to changes in food availability In Central and South America, they tend to be limited to the eastern (Atlantic) side of the continent also. In 1993 this species was first recorded in El Salvador however, and the discovery of a breeding pair in 2004 confirms that the species is a resident there[3]. El Salvador ( República de El Salvador,) is a country in Central America.

These birds forage on the ground or in low vegetation, sometimes probing with its bill. They mainly eat arthropods, but also seeds and berries. Arthropods are Animals belonging to the Phylum Arthropoda (from Greek ἄρθρον arthron, " Joint " A seed (in some plants referred to as a kernel) is a small embryonic Plant enclosed in a covering called the seed coat usually with some stored The word berry has two meanings one based on a botanical definition the other on common identification In winter, they often feed in flocks.

Nesting occurs throughout the summer months. The nest is also on the ground, covered with a roof woven from grasses. There may be more than one nesting female in a male's territory.

The numbers of this species increased as forests were cleared in eastern North America; their numbers are now shrinking with a decline in suitable habitat. A habitat (which is Latin for "it inhabits" is an Ecological or environmental area that is inhabited by a particular Species. On the other hand, its range is expanding in parts of Central America towards to Pacific (western) side of the continent[3]. The Pacific Ocean is the largest of the Earth 's Oceanic divisions
