Order and family The order
Passeriformes, commonly referred to as "perching birds", is the largest and most diverse order of birds. These birds are found worldwide, excluding Antarctica, but have their highest concentration in the tropics. Their sizes range from just a few grams to over a kilogram in weight, and they are generally colorful songbirds. The family
Corvidae is in the order Passeriformes and includes the jays, magpies, and crows. Most of the birds are strongly built, are stout-billed, and are some of the largest birds in Passeriformes. In most cases there exists no
sexual dimorphism. Corvids have loud, harsh voices and an advanced social organization. Individuals in a colony will take care of one another and generally a pair will mate for life. Corvids are extremely intelligent and are resourceful scavengers. There are over 120 known species in the family Corvidae. ,
Ecuador Related species Similar species include the
beautiful jay, the
black-collared jay, and the
white-collared jay. The turquoise jay is sympatric with the black-collared jay; both inhabit northwestern South America, though the black-collared jay is less green in color and has a much longer tail. The white-collared jay is also prevalent in northwestern South America, but differs in appearance from the turquoise jay by a white forecrown, black undertail, thin white collar, and general darker blue color. The beautiful jay is a rare jay that exists only on a thin strip of the western Andes between Colombia and Ecuador. It is different from the turquoise jay by a darker color overall, smaller size, and the absence of a black collar. The turquoise jay has no subspecies. ==Description==
