Geographic Range
Green-cheeked conures (
Pyrrhura molinae
) are native to dense forests throughout Paraguay, northwestern Argentina, and Bolivia.
They have also been observed in several parts of Brazil but in fewer numbers. Green-cheeked
conures have been found in the western portions of Mato Grosso and Mato Grosso do
Sul, two neighboring states of Brazil. These birds have been observed in each of these
locations year-round. However green-cheeked conures that live at higher elevations
are known to migrate, descending farther south within their range in fall and winter
(March to August).
- Biogeographic Regions
- neotropical
Habitat
Green-cheeked conures hatch in nests made in the holes of various trees throughout
the dry forests of western Mato Grosso and Mato Grosso do Sul, Brazil. These birds
also nest throughout deciduous lowland woodlands, secondary forests, gallery woodlands,
and humid subtropical forests of Paraguay, Argentina, and Bolivia. Once they grow
their flight feathers, green-cheeked conures are able to fly throughout the South
American forests they inhabit, reaching elevations up to 2,600 m. They spend most
of their lives in the treetops of these forests and woodlands.

Physical Description
Green-cheeked conures are distinguished from other conure species by their signature
green coloration, specifically on their cheeks. There are six subspecies of green-cheeked
conures including
Pyrrhura molinae molinae
,
P.m. phoenicura
,
P.m. sordida
,
P.m. restricta
,
P.m. australis
, and
P.m. flavoptera
. Each subspecies has a few different characteristics regarding coloration and feather
patterns. The following description describes
Pyrrhura molinae molinae
which is considered the signature green-cheeked conure: from forehead to nape, adult
green-cheeked conures have brown or gray feathers, followed by a variation of gray,
white, and brown feathers down their chests. Their eyes are brown and surrounded by
bare, white eye rings. Their beaks are a gray or brown color. Their hindnecks are
covered in mostly gray feathers but there are occasionally a few blue feathers. There
is a variation of yellow and orange feathers on their lower abdomens. Green-cheeked
conures have long red tail feathers occasionally tipped with blue. Their feet are
most commonly gray, however some have a mutation that results in pink feet. Juveniles
have many of these characteristics, however their blue flight feathers, long tail
feathers, and the colorful feathers on their abdomens do not develop until they mature.
- Other Physical Features
- endothermic
- bilateral symmetry
- Sexual Dimorphism
- sexes alike
Reproduction
Male green-cheeked conures court females by puffing up their feathers to make themselves
appear larger and more attractive. Males also lift their tail feathers up and back
into females to display their affection. If a female accepts this courtship display,
she will also stick her tail feathers up toward the sky and wag them at her new mate.
During courtship, green-cheeked conures also exhibit regurgitation and burrowing behaviors.
During their breeding season, male and female green-cheeked conures copulate in small,
dark tree holes, where they eventually prepare nests.
- Mating System
- monogamous
Green-cheeked conures are known to breed in February throughout their geographic range.
After copulation, females gestate for a couple of days before laying three to eight
eggs. Weaning of hatchlings occurs after 45 to 70 days. After weaning, young green-cheeked
conures only live with their parents for another three to six weeks before becoming
independent. These birds reach sexual maturity between the ages of one and three.
Once they are sexually mature, they search for a life-long mate.
- Key Reproductive Features
- iteroparous
- seasonal breeding
- gonochoric/gonochoristic/dioecious (sexes separate)
- sexual
- oviparous
Green-cheeked conure parents build their nests in tree holes about 18 inches deep
using a variety of materials, including twigs, leaves, and dry wood chips. These materials
prevent fungus growth inside nests. Green-cheeked conures have been reported to be
outstanding parents. After female green-cheeked conures lay their eggs, both parents
take turns incubating them. As green-cheeked conure chicks grow and develop, parents
feed and protect their young until they become independent. There is typically no
post-independence association between parents and their offspring, even if they remain
within the same flock.

Lifespan/Longevity
On average, green-cheeked conures, both in the wild and in captivity, are expected
to live between 25 and 30 years. Interestingly enough, they have must shorter lifespans
in captivity than expected. This is often due to owner neglect and poor diet in pet
green-cheeked conures.
Behavior
Green-cheeked conures are highly mobile and social birds. They typically form flocks
of 10 to 20 birds and are rarely observed alone or far from their flock. There is
no known social hierarchy or particular social system in green-cheeked conures. They
are known to remain within dense forests and jungles of Paraguay, Argentina, Bolivia,
and Brazil year-round. In general, green-cheeked conures are not a migratory bird,
however some are known to be altitudinal migrants. Green-cheeked conures are active
during the day and spend the majority of their time in tall trees in the forests and
jungles they inhabit.
Home Range
Green-cheeked conures do not have a fixed home range and are not considered territorial
birds.
Communication and Perception
Green-cheeked conures rely heavily on their eyes to perceive their environment. They
are well-known for their sensitive olfactory and respiratory systems, which also affect
how they perceive their environments. To communicate between one another, green-cheeked
conures use a variety of high-pitched and low-pitched chirps, whistles, screams, chatters,
and tongue-clicks. They use posture, head bobbing, feather ruffling, and tail-wagging
to communicate with each other as well. Green-cheeked conures may also communicate
with one another through physical contact, typically with their heads or beaks, as
a way of showing affection. They are skilled at mimicking the noises of other birds
and objects in their environment. In captivity, green-cheeked conures have been reported
mimicking the sounds of household items and human voices.
Food Habits
As fledglings, green-cheeked conures eat what their parents provide them. This includes
a combination of fruits, seeds, nuts, and bits of flowers. Adult green-cheeked conures
have an incredibly diverse and flexible diet. They eat fruits from the deciduous and
semi-deciduous trees in their habitats, including figs, mangoes, papaya, and oranges.
They also consume the seeds and pulp from these fleshy fruits. Green-cheeked conures
are known to sometimes consume flowers from the trees they inhabit as well as the
nectar from those flowers. They enjoy a variety of seeds and nuts including sunflower
seeds, brazil nuts, paradise nuts, and cashews.

Predation
False vampire bats (
Vampyrum spectrum
) and ornate hawk-eagles (
Spizaetus ornatus
) are two known predators of green-cheeked conures. When green cheeked conures are
in groups, these predators often do not attack, likely because they are confused by
the large numbers. If either of these predators decided to attack a flock of green-cheeked
conures, several green-cheeked conures would first alert the rest of the flock, after
which the group would immediately disperse. Despite their colorful feathers green-cheeked
conures are able to hide from predators in the areas they inhabit. Green-cheeked conures
make their nests within tree holes, which protect their young from predators. The
small openings to their nests are too small for common green-cheeked conure predators
to access. Flocking has proved to be the most effective anti-predator adaptation that
these birds have.
- Anti-predator Adaptations
- mimic
- cryptic
Ecosystem Roles
Green-cheeked conures play an important role in the dispersal of seeds for many seed-bearing
plants throughout the rainforests and deciduous forests of Bolivia, northwestern Argentina,
Paraguay, and Brazil. Green-cheeked conures cannot digest the seeds of fruits they
consume. Therefore, through defecation while flying, they spread seeds to new areas.
Although they are difficult to catch when in flocks, they are nevertheless preyed
upon by false vampire bats (
Vampyrum spectrum
) and ornate hawk-eagles (
Spizaetus ornatus
).
- Ecosystem Impact
- disperses seeds
Economic Importance for Humans: Positive
Green-cheeked conures have become much more popular as pet birds in the United States
in recent years. They are raised on bird farms in the U.S. or are illegally traded
from Mexico and other South American countries and imported to pet stores in the U.S.
- Positive Impacts
- pet trade
Economic Importance for Humans: Negative
The trapping, transport, and lack of sanitary conditions connected with trading and
breeding green-cheeked conures has resulted in the exchange of diseases like Polyoma
virus, Psittacosis (or parrot fever) and Chlamydiosis. Although it is rare for humans
to contract Polyoma virus, Psittacosis and Chlamydiosis are more commonly contracted
by humans. These diseases can also be passed along from parents to their young and
can result in deformities. Disease and deformities in green-cheeked conures have a
large negative impact on the green-cheeked conure trade and bird sales in pet stores.
- Negative Impacts
- causes or carries domestic animal disease
Conservation Status
There is currently little concern for native green-cheeked conure populations. Populations
are decreasing, but not at an alarming rate. However, this will change as deforestation
and habitat fragmentation gradually destroy the forests that green-cheeked conures
inhabit. In an effort to prevent severe damage or loss to native green-cheeked conure
populations, their entire geographic range has been designated as a conservation site.
South American countries included in this range are working to protect the water resources
and other resources that green-cheeked conures use.
