Turquoise-Fronted Amazon
The Turquoise-Fronted Amazon (Amazona aestiva), also called the turquoise-fronted parrot, the blue-fronted amazon and the blue-fronted parrot is a South American species of amazon parrot and one of the most common amazon parrots kept in captivity as a pet or companion parrot. Its common name is derived from the distinctive turquoise marking on its head just above its beak.
The turquoise-fronted amazon is a 38 cm long, primarily green parrot. They have yellow feathers on their face and crest, and blue feathers above their beak on their forehead. Blue and yellow distribution vary widely between people. Its beak is predominantly black, in contrast to most other Amazona parrots. The feathers do not exhibit overt sexual dimorphism to the human eye, but spectrometric analysis, which reproduces a parrot's tetrachromatic vision, reveals distinct differences between the sexes' feathers. Parrot juveniles have darker irises and a duller appearance.
