Red-winged tinamou

The red-winged tinamou (Rhynchotus rufescens) is a medium-sized ground-living bird from central and eastern South America.<ref name="Clements">Clements, J (2007)</ref> Other common names for the species include perdiz grande, rufous tinamou, and ynambu.

Taxonomy

All tinamou are from the family Tinamidae, and in the larger scheme are also ratites. Unlike other ratites, tinamous can fly, although in general, they are not strong fliers. All ratites evolved from prehistoric flying birds, and tinamous are the closest living relative of these birds.<ref name="Davies">Davies, S. J. J. F. (2003)</ref>

Coenraad Jacob Temminck first identified the red-winged tinamou from a specimen from São Paulo state, Brazil, in 1815.<ref name="Davies"/>

Subspecies

The red-winged tinamou has three subspecies:

• R. r. rufescens, the nominate race, occurs in southeastern Peru, Bolivia, eastern Paraguay southeastern Brazil and northeastern Argentina,<ref name="Clements" /> and possibly Uruguay<ref name="Davies" />
• R. r. catingae occurs in central and northeastern Brazil<ref name="Clements" />
• R. r. pallescens occurs in northern Argentina; eastern Formosa, Chaco, Santa Fé, Córdoba, La Pampa, Buenos Aires, Entre Ríos, Corrientes, and Rio Negro<ref name="Clements" />

Previously, the taxon maculicollis was considered a subspecies of the red-winged tinamou, but following SACC it is now considered a species in its own right; the huayco tinamou.<ref>Remsen Jr., J. V. (2000)</ref>

Etymology

Its common name refers to the bright rufous primaries, which mainly are visible in flight.

Description

The red-winged tinamou is approximately Template:Convert in length, and weighs Template:Convert, and the female may be slightly larger. It has a black crown, rufous primaries, and light gray to brown underneath. It may have black bars on flanks, abdomen and vent.<ref name="Davies" /> Also, the throat is whitish, the foreneck and breast are cinnamon. The curved bill is horn-coloured with a blackish culmen. Juveniles are duller.

Range

Its range is southeastern, northeastern and central Brazil, eastern Paraguay, southeastern Peru, Bolivia and eastern Argentina<ref name="Clements" />

Habitat

At lower elevations (Template:Convert), it favours marshy grasslands (seasonally flooded) and forest edges. While, at higher elevations, up to Template:Convert, it will frequent arid shrubland, pastures, and grain fields.<ref name="Davies" /><ref name="BLI">BirdLife International (2008)</ref> Overall it prefers dry savanna.<ref name="BLI" />

Behavior

The red-winged tinamou have vocal males that are a longs ringing single whistle followed by shorter sad whistles. The female does not call. This species is most active during the hottest parts of the day.<ref name="Davies" />

Feeding

Its diet varies by season; it taking insects and other small animals (even small mammals) in the summer, and switching to vegetable matter, such as fruits, shoots, tubers and bulbs, in the winter. It can be an agricultural pest, feeding on cereals, rice and peanuts, as well as being predatory, taking poisonous snakes and even jumping up into the air to snatch an insect off a leaf.

Reproduction

The male of the species attracts the female by follow feeding and after the attraction will move to the nest where she lays her eggs that he will incubate only and then raise the chicks.<ref name="Davies" />

Conservation

Like all tinamous, the red-winged tinamou is a popular target for hunters, and in areas of high human population density number have declined, but the species has also increased in some areas where forest clearance has created favourable habitat. Overall, it is not considered threatened and is therefore listed as Least Concern by IUCN.<ref name="iucn status 11 November 2021" /> It has an occurrence range of Template:Convert.<ref name="BLI" />
