Pampas meadowlark description

GenusSturnella (1)

The male pampas meadowlark is a rather striking bird, with a bright red throat and breast and a contrasting dark, blackish body, edged in brown (2) (3) (4) (5). The face bears a small, bright red stripe above the eye, and a distinct, cream-coloured ‘eyebrow’ stripe. The underwing is black (2) (3). The female pampas meadowlark is duller brown and more streaked, with a buff-coloured throat and a smaller, paler pinky-red area on the belly (2) (3) (4) (5). The species is quite similar in appearance to the long-tailed meadowlark (Sturnella loyca) and white-browed blackbird (Sturnella superciliaris), with which its range overlaps, and is intermediate in size between the two (3). However, S. loyca has browner colouration, a longer tail, and pale, not black, underwings, while S. superciliaris has a much shorter beak (2). The pampas meadowlark sings with a series of short, buzzy, high-pitched notes, and the call is a dull, raspy ‘jzeet’ (2).

Also known as
lesser red-breasted meadowlark.
Sturnella defilippi, Sturnella militaris.
Length: 21 cm (2)
60 - 72 g (3) (4)

Pampas meadowlark biology

Meadowlarks are often seen walking about in the open or perching on fences or clumps of grass (5). The diet is thought to include seeds, shoots and insects (2) (3), and may comprise mainly insect larvae when feeding young (3). The pampas meadowlark nests in groups, which range in size from around 2 to as many as 66 breeding males (4). The male meadowlarks maintain small territories (6), which are also defended against neighbouring white-browed blackbirds (3). Males perform a regular and conspicuous display, perching on low tufts of grass to sing, and singing while making an ascending flight (3) (6). Breeding occurs from November to December, and the nest is built on the ground, concealed under a tuft of grass (4) (6). The nest itself is cup-shaped, constructed mainly from grass, and the nests of the group are usually arranged in a cluster (7). Three to four eggs are laid (2) (7), but in one study around half of all nests suffered predation (7).


Pampas meadowlark range

The pampas meadowlark is restricted to parts of eastern Argentina, with smaller numbers in eastern Uruguay and the extreme south of Brazil (2) (4) (5).


Pampas meadowlark habitat

The pampas meadowlark inhabits natural open grasslands, usually avoiding shrubby and forested areas and field edges (4) (6). The species will sometimes use planted pastures and cultivated fields, but only where grazing is not intensive and vegetation height is not too low (2).


Pampas meadowlark status

Classified as Vulnerable (VU) on the IUCN Red List (1).

IUCN Red List species status – Vulnerable


Pampas meadowlark threats

Once common and widespread across much of the pampas grasslands of Argentina, Uruguay and southern Brazil, the range of the pampas meadowlark has decreased by 90 percent since 1900 (2) (4) (8). With a population estimated at just 7,500 adult birds, the pampas meadowlark may now occupy a total area of no more than 150 square kilometres (8), a decline due primarily to habitat loss as natural grasslands have been converted for intensive agriculture and cattle ranching (2) (4) (5) (6). The pampas grasslands are believed to be one of the most severely degraded ecosystems in Argentina (7) (9), and the rate of grassland conversion is outstripping the rate of grassland regeneration by about three to one (2).

Habitat loss may also have knock-on impacts on the pampas meadowlark, decreasing nesting success though trampling cattle, increased predation, and by benefiting brood parasites like the shiny cowbird (Molothrus bonariensis) (2) (4). Overgrazing and inadequate management of fields also degrade breeding habitat (6), and competition with the long-tailed meadowlark and white-browed blackbird may negatively impact the pampas meadowlark (2) (4). Some trapping of pampas meadowlarks for trade has also been reported, but is not extensive (2).


Pampas meadowlark conservation

Although recent surveys suggest the pampas meadowlark is not as scarce as previously thought, ongoing habitat loss and the continued contraction of the species’ range mean it needs close monitoring (2) (4) (5). In light of these threats, some have suggested that the species should be uplisted to Endangered (8). The pampas meadowlark is protected by law in Brazil and Uruguay, and trapping is banned in Argentina (2). Other conservation measures proposed include surveying and monitoring populations, and investigating the threats posed by predation, nest trampling, brood parasitism, and competition with other Sturnella species. It will also be important to monitor the pampas meadowlark’s preferred habitat, and to monitor agricultural land to ensure habitat loss does not exceed habitat gain (2) (4).

Brood parasite
An animal that lays its eggs in the nests of members of its own or other species; the host then raises the young as their own.
Stage in an animal’s lifecycle after it hatches from the egg. Larvae are typically very different in appearance to adults; they are able to feed and move around but usually are unable to reproduce.
The vast, grassy plains of temperate central and southern South America.
An area occupied and defended by an animal, a pair of animals or a colony.
