The plush-headed jay 🦜🦜🦅#Cyanocorax chrysops

The plush-headed jay Cyanocorax chrysops lives in southwestern Brazil, Bolivia, Paraguay, Uruguay and northeastern Argentina.

It is an elegant bird of medium size, with dark plumage and a creamy-yellow breast; the voluminous tail is also cream-colored - from the inside out and at the end. On the head is a tuft in the form of a plush cap.

Systematically, magpies and cuckoos are considered the closest relatives of jays. Unlike other ravens, which are distinguished by a strong physique, jays are light and elegant. The streamlined body, small beak, thin prehensile paws and, especially, a long tail make them look like a lightweight magpie. 

It is noteworthy that the blue color of the feathers in jays is not due to coloring substances, but to the refraction of light in the microscopic grooves of the fan. If the pen is crushed, its microstructure will be broken and the blue color will disappear
