Red-tailed Amazon

Description

The red-tailed amazon (Amazona brasiliensis),also known as the red-tailed parrot,is a species of parrot in the family Psittacidae.It is endemic to coastal regions in the south-east Brazilian states of São Paulo and Paraná.The bird has been threatened by habitat loss and capture for the wild bird trade,and is a symbol of the efforts to conserve one of the Earth's most biologically diverse ecosystems.Consequently,it is considered vulnerable by BirdLife International and the IUCN.In 1991-92,the population had fallen below 2000 individuals.Following on-going conservation efforts,the most recent estimate suggests a population of around 6600,indicating that this species is recovering from earlier persecution.A recent study shows that the population of this species is stable at Paraná state,Southern Brazil,revealing population trend fluctuation during the last 12 years.Red-tailed amazons weigh around 425 g (15.0 oz) and are approximately 35 cm (14 in) long.As expected from its common name,it has a broad red band on its tail,but as it largely is limited to the inner webs of the feathers,it is mainly visible from below or when the tail is spread open.Additionally,the tail has a broad yellow tip,and the outer rectrices are dark purplish-blue at the base.The remaining plumage is green,while the throat,cheeks and auriculars are purple-blue,the forecrown is red,and the retrices are broadly tipped dark blue.It has a yellowish bill with a blackish tip to the upper mandible,a pale gray eye ring,and orange irises.Juveniles have a duller plumage and a brown irises.
