Jays make up the family Corvidae. They are medium to large in size with strong feet and bills, and rictal bristles. Jays undergo a single molt each year (most passerines molt twice). Jays are highly social birds found usually in pairs or family groups. They are rather vocal and confident. Some species have complicated social and breeding systems, which are poorly understood.
They are among the most colorful Neotropical birds. Corvids as they are known, are considered the most intelligent of the birds. Their total brain-to-body mass ratio is equal to that of great apes and cetaceans, and only slightly lower than in humans. There are two genera and six species within the family Corvidae known to occur in Peru. Photo: White-tailed Jay.
