Monk Parakeet

The Monk Parakeet is a small, stocky parrot native to temperate and subtropical South America, notable for being one of the few parrot species that builds its own nest from sticks rather than using a cavity. It has also established numerous naturalized populations elsewhere in the world.

Plumage is mostly bright green above, with a pale grey forehead, face, throat, and breast, and pale blue-green flight feathers visible in flight. The belly shows a wash of yellowish green, and the bill is a pale horn color.

Key field marks

• Grey forehead, face, and breast contrasting with green upperparts
• Pale, unmarked horn-colored bill
• Blue-green tinge in the flight feathers
• Bulky stick nests, often visible on utility poles or in large trees

Similar species

The grey face and breast readily distinguish the Monk Parakeet from most other small green parakeets, which typically show green or yellow faces. Its bulky communal stick nests are also a strong identification clue where present, since no other common parakeet builds this type of structure.

Range

Monk Parakeets are native to a broad area of central and southern South America, including parts of Bolivia, Brazil, Paraguay, Uruguay, and Argentina. Escaped and released birds have established self-sustaining populations in parts of North America, Europe, and elsewhere.

Habitat

In its native range it occupies open and semi-open habitats such as savanna, dry woodland, palm groves, and agricultural land. Introduced populations thrive readily in urban and suburban settings with parks, trees, and utility structures.

Movements

Monk Parakeets are largely non-migratory and resident year-round, remaining near their nest structures throughout the year.

Social behavior

Highly social, Monk Parakeets live in colonies and are rarely seen alone, foraging, roosting, and nesting communally throughout the year.

Voice

Calls are loud, harsh, and chattering, including sharp repeated squawks given frequently both in flight and around the nest colony.

Feeding

They feed on a wide variety of seeds, fruits, buds, and blossoms, foraging both in trees and on the ground, and readily exploit agricultural and urban food sources.

Nesting and breeding

Unique among most parrots, Monk Parakeets build large, bulky stacked-stick nests with multiple chambers, often used and expanded communally by several pairs within a single structure, frequently sited on poles, transmission towers, or large trees. Each pair maintains its own nest chamber, laying 5-8 eggs, and nests are reused and enlarged year after year, sometimes growing to substantial size.
