Geographic Range
Found in the Americas, the extinct
Conuropsis carolinensis
was found from southern Florida to North Carolina and in coastal areas as far north
as New York. Carolina parakeets occurred in the Gulf states as far west as eastern
Texas and north along the Arkansas, Missouri, Mississippi, and Ohio Rivers and their
tributaries. Carolina parakeets were also recorded in South Dakota, Iowa, Wisconsin,
Michigan, Ohio, and West Virginia. Westernmost occurrences were in eastern Colorado.
Habitat
Overgrown and heavily timbered lands bordering swamps and rivers were preferred habitats
of Carolina parakeets. These parakeets also lived on farmlands and ate the crops.
They nested in hollowed trees in large groups. They preferred sycamore woodlands and
cypress swamps.

Physical Description
Male and female adults were identical in plumage, however males were slightly larger than females. The majority of the plumage was green with lighter green underparts. The primary feathers were mostly green, but with yellow edges on the outer primaries. The shoulders were yellow, continuing down the outer edge of the wings. Thighs were green towards the top and yellow towards the feet. The legs and feet were light brown. The most distinguishing characteristic of this species was the orange forehead and face. The orange feathers extended to behind the eyes and upper cheeks (lores). The skin around the eyes was white and the beak was pale flesh colored. The plumage on the head was entirely bright yellow.
Young Carolina parakeets differed slightly in coloration from adults. The face and
entire body was green, with paler underparts. They lacked yellow or orange plumage
on the face, wings, and thighs. Hatchlings were covered in mouse-gray down, until
about 39-40 days when green wings and tails appear. Fledglings had full adult plumage
at around 1 year of age.

Reproduction
Some sources say that Carolina parakeets were monogamous, having only one partner
for their entire lives. However, no studies were conducted on mating systems and many
birds apparently shared nests.
There is little information available on reproduction in Carolina parakeets. They
bred in the spring, producing 2 to 5 eggs in each clutch that were then incubated
for 23 days.
- Key Reproductive Features
- iteroparous
- seasonal breeding
- gonochoric/gonochoristic/dioecious (sexes separate)
- sexual
- oviparous
It is thought that females were responsible for the eggs during the incubation period.
Both parents cared for young parakeets. Adults were observed as careless when feeding
the offspring and were often unsuccessful in rearing young.

Lifespan/Longevity
No studies on lifespan were conducted while Carolina parakeets were still living.
They lived up to 30 years in captivity.
Behavior
Carolina parakeets traveled in flocks from 100 to 1000 birds. They nested with as many as 30 birds in one nest. They were presumed to be monogamous. These were highly social birds, which was probably one of the many factors that led to their extinction. When a human shot one bird, flockmates would hover over their lost flock member, making them vulnerable as well. Farmers would shoot the entire flock to save their crops. It is doubtful that Carolina parakeets migrated, as they were seen in northern states during cold winters. They were attracted to salt licks and were observed ingesting saline waters and earth as well as sand.
Carolina parakeets walked, hopped, and climbed in the trees using their beaks as a
third limb. Their flight was recorded as swift and graceful, but very loud as the
birds nearly never stay silent during flight. They engaged in mutual preening and
scratching to maintain social cohesion. They bathed with water and were observed "anting"
as well. During the day they mainly rested, roosted, or sunbathed. They fed in the
morning hours and at sunset.
Home Range
Carolina parakeets travelled as far as 48 km away from nesting sites.
Communication and Perception
Carolina parakeets cried loudly while flying. Flocks could be heard from miles away.
They were often silent when roosting, murmuring occasionally. During feeding a low,
consistent chatter was observed. When predators were sighted, Carolina parakeets would
emit shrill warning cries. Flock mates were attracted to the cries of injured birds.
Carolina parakeets also probably communicated among themselves with visual cues and
mutual preening.
Food Habits
Carolina parakeets ate primarily seeds of cockleburs (
Xanthium
sp.). They also ate the fruits and seeds of many other plants, as well as flower
buds and, occasionally, insects. They were recorded as ruining many fruit crops. They
would rip the unripe fruit off of the tree and eat the seeds. Flocks could ruin the
fruit of a particular tree in a matter of minutes. When eating, Carolina parakeets
grabbed food items with their beaks, placed it in their claws, and held onto it while
using the beak to eat the item.

Predation
Humans preyed on Carolina parakeets, they were shot and eaten as food, stuffed as
prizes, traded, and domesticated as pets. It is likely that birds of prey, such as
Cooper's hawks (
Accipiter cooperi
) and other
birds of prey
preyed on adults and fledglings. Eggs and hatchlings in nests likely fell prey to
nest predators such as raccoons (
Procyon lotor
), skunks (
Mephitidae
), squirrels (
Sciuridae
), and snakes (
Serpentes
).
Ecosystem Roles
Carolina parakeets fed mainly on cocklebur seeds (
Xanthium strumarium
) and other seeds. They played an important role in seed dispersal of these plants.
- Ecosystem Impact
- disperses seeds
Economic Importance for Humans: Positive
Carolina parakeets served a certain aesthetic role to humans. They were kept as pets,
eaten, and their feathers were traded.
Economic Importance for Humans: Negative
Carolina parakeets ruined many fruit crops, causing economic loss for farmers.
- Negative Impacts
- crop pest
Conservation Status
This species is extinct. The last sighting of the Carolina parakeet in the wild was
in 1920, however questionable sightings occurred as late as 1938. The last bird in
captivity died at the Cincinnati Zoological Garden in September 1914.
