Anatomy: Males are very brightly colored; females and young are much more subtly colored, with an olive-green back . The oriole is about 7-8 inches (18-20.5 cm) long.

Diet: Orioles mostly eat fruit and drink flower nectar. They also eat bugs, nuts, and seeds.

Nest and Eggs: Baltimore Orioles build hanging nests made of grass and tree bark. The nest is a pouch that hangs from a fork in a tree branch. In each clutch (a set of eggs laid at one time), females lay 3-6 blue-white eggs with dark markings.
