Monk Parakeet

About

The Monk Parakeet, also known as the Quaker Parrot or Caturrita, is a medium-sized, bright green parrot native to temperate to subtropical areas of South America. It is well-known for its ability to thrive in urban environments and its unique communal nesting habits. It has established feral populations in many parts of the world, including North America and Europe, often due to escaped or released pet birds.

Size & lifespan

Length

28-30 cm (11-12 in)

Wingspan

43-48 cm (17-19 in)

Weight

90-140 g (3.2-4.9 oz)

Lifespan

15-20 years in the wild, up to 30 years in captivity

Diet

Herbivore (primarily granivorous and frugivorous)

Physical characteristics

Plumage

Predominantly bright green on the back, wings, and tail. The forehead, cheeks, throat, and breast are pale gray, often with a scaly appearance. The belly is yellowish-green. Primary flight feathers are blue.

Beak shape

Strong, hooked, and relatively large for its size. Color is typically horn-colored or brownish-pink.

Eye color

Dark brown with a pale gray periophthalmic ring (bare skin around the eye)

Leg color

Grayish-pink to dark gray

Distinguishing features

Gray face and breast contrasting with green body, blue primary feathers, and its unique communal stick nests.

Juvenile appearance

Juveniles resemble adults but may have slightly duller plumage, particularly the gray areas, and a shorter tail. The beak may also be a slightly paler horn color.

Seasonal changes

No significant seasonal plumage changes.

Sexual dimorphism

Monk Parakeets exhibit very little to no sexual dimorphism; males and females are virtually identical in plumage and size. Sexing typically requires DNA testing or surgical sexing.

How to identify

1. 1

   Plumage Coloration

   Look for the distinctive combination of bright green upperparts and a pale gray face, throat, and breast. The blue primary feathers are also a key field mark, especially in flight.

2. 2

   Vocalizations

   Listen for their loud, harsh, chattering, and squawking calls. They are often heard before they are seen, especially in urban environments.

3. 3

   Nesting Behavior

   Observe for large, messy, communal stick nests, often built in prominent locations like utility poles, cell towers, or tall trees. This is a unique characteristic among parrots.

4. 4

   Social Behavior

   They are almost always seen in groups or flocks, rarely solitary. Their gregarious nature is a good indicator.

5. 5

   Flight Pattern

   Note their direct, strong flight with rapid wingbeats, often accompanied by their characteristic calls.

Habitat & range

Biomes

Forest edges, woodlands, savannas, agricultural areas, urban and suburban environments.

Geographic range

Native to central South America, including parts of Argentina, Bolivia, Brazil, Paraguay, and Uruguay. Feral populations are established in numerous countries worldwide, including the United States, Canada, Mexico, Spain, Italy, France, Belgium, and Israel.

Elevation range

Sea level up to approximately 1,000 meters (3,300 feet).

Preferred environments

Highly adaptable, preferring open woodlands, palm groves, and increasingly, human-modified landscapes such as parks, gardens, and urban areas with abundant food sources and nesting sites (e.g., utility poles, tall trees).

Behavior

Activity time

Diurnal, most active during early morning and late afternoon.

Feeding habits

Feeds primarily on seeds, fruits, nuts, berries, and flower buds. They are also known to consume agricultural crops, which can lead to them being considered pests in some regions. They forage in trees and on the ground.

Social behavior

Highly social birds, typically found in flocks ranging from a few individuals to several dozen. They are known for their communal nesting behavior, building large, multi-chambered stick nests that can house multiple breeding pairs.

Flight pattern

Direct and strong flight, often in small, noisy flocks. Their wingbeats are rapid, and they can be quite agile.

Migration pattern

Resident throughout their native and introduced ranges; they do not undertake seasonal migrations.

Territoriality

While they nest communally, individual pairs defend their specific nest chamber within the larger structure. Flocks may defend feeding territories.

Breeding & reproduction

Breeding season

Varies geographically. In their native range, typically from October to December (Southern Hemisphere spring/summer). In introduced populations, it can be earlier, often starting in late winter/early spring (e.g., February-March in North America) and extending through summer.

Nesting habits

Unique among parrots for building large, enclosed, multi-chambered stick nests. These communal nests can be massive, weighing hundreds of pounds, and are constructed in tall trees or on man-made structures like utility poles and cell towers. Each breeding pair has its own entrance and chamber within the larger structure. Both sexes participate in nest building.

Clutch size

4-8 eggs, most commonly 5-6.

Egg description

Typically white, oval to rounded-oval, and smooth. Average size is about 28 x 22 mm.

Incubation period

Approximately 23-28 days.

Fledging period

Chicks fledge (leave the nest) around 4-6 weeks after hatching.

Parental care

Both parents share incubation duties and care for the young. Juveniles remain with the family group for some time after fledging, often assisting with subsequent broods or contributing to nest maintenance.

Where to find

Field tips

1. Listen for their calls. Their loud, distinctive squawks and chattering are often the first sign of their presence. Follow the sound to locate the flock.
2. Look for nests. Scan tall trees, utility poles, and other elevated structures for their large, bulky stick nests. These nests are unmistakable.
3. Observe feeding behavior. Look for them feeding on fruit trees, seed-bearing plants, or even at bird feeders in urban areas.
4. Visit known hotspots. In areas with established feral populations, local birding groups or online resources often list specific parks or neighborhoods where they are reliably seen.

Fun facts

• The Monk Parakeet is the only parrot species known to build its own stick nest rather than nesting in tree cavities or rock crevices.
• Their communal nests can be enormous, sometimes reaching the size of a small car, and can house dozens of individual pairs.
• Feral populations in urban areas have adapted to using man-made structures like utility poles and cell towers as preferred nesting sites, sometimes causing power outages due to nest material interfering with electrical equipment.
• They are highly intelligent and can mimic human speech, which has contributed to their popularity as pets and, consequently, their establishment in new regions.
• The name 'Monk Parakeet' refers to the gray cap and breast plumage, which resembles a monk's cowl.
