Beautiful Jay
The Beautiful Jay is a rare, near-threatened jay restricted to the humid cloud forests of the western Andes in Colombia and Ecuador. It has striking brilliant blue plumage with a black mask, and is considered one of the most attractive jays. It forages in small groups in the forest canopy and midstory, feeding on insects, fruits, and small vertebrates.
