The Carolina parakeet was 12.5 inches long with a wingspan of about 22 inches. The bird was mostly green with an orange head, a yellow neck, and white legs, its tail feathers giving the impression of being long and pointed. Though skilled climbers, parakeets seemed reluctant to walk from place to place, instead going airborne even to turn around. Sometimes human traits such as laziness were ascribed to these birds. Their voice was said to be loud, harsh, and grating. Though generally not adept at speaking, occasionally the parakeet imitated sounds or words, and some trainers who began with very young birds were successful in teaching them to mimic a limited number of words from human speech.
Parakeets were thought to mate for life and show signs of close attachment to their own kind. Some, in fact, were acclaimed "love birds." When a parakeet died or was killed, a host of chattering birds promptly surrounded its body. Although no evidence seems to suggest that these birds
Carolina parakeets ate thistle seeds and cockleburs, birch buds in April, and beechnuts and chinquapins in the autumn. They also preferred to drink salty seawater when it was available. Orchards of European settlements were very appealing to flocks of parakeets, whose bills were ideal for splitting the fruit to get at the seeds. Raided orchards were stripped bare and the ground underneath covered with broken fruit that soon spoiled.
The Carolina parakeet rapidly declined in the late nineteenth century. Landowners began hunting the birds, which had become pests and were also prized as food and for their colorful feathers, with which Victorian milliners decorated women's hats. Parakeets seemed to possess an uncommon degree of curiosity, and they appeared to be attracted rather than dispersed by gunshots. Their communal reaction to their dead also made them easy targets. In addition, the increasing human population in the rural regions of the southeastern United States began to deprive these birds of their natural habitat. The species probably fled North Carolina by the 1780s but may have lingered in South Carolina until the 1860s. A few later reports of sightings from Tennessee, South Carolina, and Florida appear credible, but Carolina parakeets were described as endangered soon after 1900 and became extinct in the wild early in the twentieth century, the final captive specimen dying in the Cincinnati Zoo on 21 Feb. 1918.
