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. ("Nature Serve, Conuropsis carolinensis", 2005; Fuller, 2001; Laycock, Audobon Magazine, March 1969; Snyder and Russell, 2002)

Biogeographic Regions
nearctic (Native )

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. ("Parakeets", 2000; Fuller, 2001; Mauler, 2001; Snyder and Russell, 2002)

Habitat Regions
temperate ; terrestrial

Terrestrial Biomes

Other Habitat Features
agricultural ; riparian

Physical Description

Average mass
280 g
(9.87 oz)

Range length
32 to 34 cm
(12.60 to 13.39 in)

Range wingspan
53 to 58 cm
(20.87 to 22.83 in)

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. ("Nature Serve, Conuropsis carolinensis", 2005; Fuller, 2001; Mauler, 2001; Rising, 2004; Snyder and Russell, 2002)

Other Physical Features
endothermic ; homoiothermic; bilateral symmetry

Sexual Dimorphism
male larger

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. (Laycock, Audobon Magazine, March 1969; Snyder and Russell, 2002)

Breeding interval
Carolina parakeets bred once a year.

Breeding season
Breeding usually occurred between March and April.

Range eggs per season
2 to 5

Average time to hatching
23 days

Range time to fledging
18 to 19 days

Average age at sexual or reproductive maturity (female)
1 years

Average age at sexual or reproductive maturity (male)
1 years

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. (Snyder and Russell, 2002; Snyder and Russell, 2002)

Key Reproductive Features
seasonal breeding ; gonochoric/gonochoristic/dioecious (sexes separate)

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. (Howell, 1932; Rising, 2004; Snyder and Russell, 2002; Strattersfield and Capper, 2000)

Parental Investment
altricial ; pre-fertilization (Provisioning, Protecting: Female); pre-hatching/birth (Provisioning: Female, Protecting: Female); pre-weaning/fledging (Provisioning: Male, Female, Protecting: Male, Female)

Lifespan/Longevity

Range lifespan
Status: captivity

10 to 30 years

No studies on lifespan were conducted while Carolina parakeets were still living. They lived up to 30 years in captivity. (Snyder and Russell, 2002)

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. ("Parakeets", 2000; "Nature Serve, Conuropsis carolinensis", 2005; Howell, 1932; Rising, 2004; Snyder and Russell, 2002; Strattersfield and Capper, 2000)

Key Behaviors
arboreal ; scansorial; flies; diurnal ; crepuscular ; sedentary ; social ; colonial

Home Range

Carolina parakeets travelled as far as 48 km away from nesting sites. ("Parakeets", 2000; Howell, 1932; Snyder and Russell, 2002)

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. ("Parakeets", 2000; "Nature Serve, Conuropsis carolinensis", 2005; Laycock, Audobon Magazine, March 1969; Snyder and Russell, 2002)

Communication Channels
visual ; tactile ; acoustic

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. (Greenway, JR., 1967; Howell, 1932; Snyder and Russell, 2002; Strattersfield and Capper, 2000; Greenway, JR., 1967; Howell, 1932; Snyder and Russell, 2002; Strattersfield and Capper, 2000)

Animal Foods
insects

Plant Foods
seeds, grains, and nuts; fruit; flowers

Predation

Known Predators
  • Humans (Homo sapiens)


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). (Fuller, 2001; Greenway, JR., 1967; Snyder and Russell, 2002)

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. (Snyder and Russell, 2002)

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. (Laycock, Audobon Magazine, March 1969; Snyder and Russell, 2002)

Positive Impacts
pet trade ; food ; body parts are source of valuable material

Economic Importance for Humans: Negative

Carolina parakeets ruined many fruit crops, causing economic loss for farmers. ("Nature Serve, Conuropsis carolinensis", 2005; Fuller, 2001; Howell, 1932; Mauler, 2001; "Nature Serve, Conuropsis carolinensis", 2005; Fuller, 2001; Howell, 1932; Mauler, 2001)

Negative Impacts
crop pest

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. (Howell, 1932; Mauler, 2001; Rising, 2004; Snyder and Russell, 2002; Strattersfield and Capper, 2000)
