Brown-backed parrotlet

The brown-backed parrotlet (''Touit melanonotus'') also known as the black-backed parrotlet, the black-eared parrotlet, and Wied's parrotlet, is a small () green parrot found in south-eastern Brazil from Bahia to southern São Paulo. It has a dark brown mantle and back, brown ear coverts, and red outer tail with back tips. They frequent humid forest from (occasionally down to sea level), and are mostly found in small flocks of 3–20 birds.
==Ecology==
It is mostly known from lower montane evergreen forest at , but also up to in the Itatiaia National Park. In addition it is found in near sea-level in Bahia and São Paulo.〔F. Olmos in litt. (1999) 〕 Seasonal migration or dispersal is suspected, though this may amount to little more than short altitudinal movements. Food items are poorly studied but include large leguminous seeds, fruit of ''Rapanea acuminata'', ''Clusia'' sp. and mistletoes.
Observed feeding on ''Clusia criuva'' where presumed adults pluck the fruit from the tree snipping the stalk with their bills and carry the fruit to a more secure location on a firmer branch where they open the fruitwith their bill wedging it against the branch prising the seeds out with their tongue; they do not use their feet at any time in the feeding process as some other ''psittacids'' do. Some individuals that were presumed to be young birds were seen to eat the fruits in ''situ'' and did not pluck them.〔
Breeding is suspected to occur from September to October.〔Collar (1997a) 〕 Well grown young birds were observed being fed by adults in Ubatuba, São Paulo state, January 2010. Young birds can be differentiated by their paler orbital ring and their cere being flesh coloured as opposed to dark grey in adults.〔
