Description 2 subspecies:

The subspecies Touit surdus chryseurus it has been proposed to birds of northeastern range on the basis of dubious lateral tail feathers more brownish and smaller.

  • Touit surdus chryseurus

    (Swainson, 1823) – Side tail feathers, brown / yellow; smaller.

  • Touit surdus surdus

    (Kuhl, 1820) – Nominal.

Habitat:

They live mainly in evergreen forests lowland, although occasionally they extend to the adjacent lower mountain slopes. Birds have been observed in the canopy of a secondary forest fragment surrounded by open fields; Other reports suggest that birds visit fruiting trees in deforested areas to feed.

You can visit, occasionally, cocoa plantations where trees shade the crop plants, but this has not been tested. They are to 700 m in Alagoas and to 800 m in Espirito Santo, Rio de Janeiro and São Paulo. The Brown-backed Parrotlet They seem to live in flocks (mainly 6-12), perhaps you composed of family groups.

Recent observations suggest that this species is resistant habitat alteration.

Reproduction:

The reproduction of this species practically is not registered. A female observed in September Alagoas, He was not in breeding condition.

Food:

Foods reported in feed Brown-backed Parrotlet are fruits Spondias lutea and Rapanea schwackeana

Distribution:

Tamaño de su área de distribución (reproductor/residente ): 1.680.000 km2

The distribution of the Brown-backed Parrotlet It extends through Atlantic forests of eastern Brazil, including coastal areas of the northeastern states of Paraíba, Pernambuco and Alagoas with a record Camocim in the North of Ceará, where there are fragments of rainforest in coastal areas.

Existen sporadic records but widespread (mainly) on the shores of Bay and Espirito Santo, and in Rio de Janeiro, for example in Teresopolis, around the Itatiaia National Park, new Freiburg and Cabo Frio, with some reports São Paulo southwest to Cardoso Island, near the border with Paraná. The reports of For and Goiás They are not substantiated and they are probably wrong. The apparent seasonal distribution of the species in some areas suggests migration trends.

They seem to be distributed at low densities and (except a report in the lower basin Tiete river in Sao Paulo) It was considered a rare species in the nineteenth century. Like other members of the genus is, without a doubt, ave a difficult to observe, and often overlooked. However, many ancient villages are no longer inhabited, with forests completely eliminated or severely degraded lowland, especially in the north of the mountain range, where you can be almost extinct. In the news They are distributed in several protected areas.

Distribution 2 subspecies:
Conservation:

• Current red list category of the UICN: Vulnerable.

• Population trend: Decreasing.

Population size: 2500-9999 specimens.

Justification of the red list category

This species is classified as Vulnerable because its population is small and declining rapidly due to continuous deforestation. It has been found that it is more resistant to forest fragmentation of what was thought first, and may be sub-registered instead of actually little, especially in the southern part of its range.

Justification of the population

The species is generally rare; Its population is in the band 2.500-9.999 mature individuals, equivalent to 3.750-14.999 individuals, round here 3.500-15.000 individuals.

Justification of trend

rapid and continuous population decline is suspected on the basis of continuous destruction and fragmentation of habitat.

In captivity:

Rare and unknown in captivity. Any captive individual (it can not be released) It should be part of a conservation program well managed to ensure continuity of this species.
