An unexpected sight on the University of Bridgeport campus are the green monk parakeets. Natives of Argentina, Brazil, Uruguay, Paraguay, and central Bolivia, they have been imported into the United States as pets. It is generally believed that in the late 1960's, a container of parakeets was dropped and broke open at Kennedy Airport in New York. Several birds escaped and established wild populations in Long Island. Since then the birds have spread into Connecticut with populations reported from Branford to Norwalk. The original birds have probably been joined by escaped pets.
On the U.B. campus, the parakeets nest in the white pine trees near Barnum Hall. The nests are large and made of sticks. One in the Black Rock section of Bridgeport measured 9 feet by 5 feet. Some nests in South America have been known to be as big as 15 to 20 cubic feet and weigh several hundred pounds. Within a nest, the nesting chamber is 7-9 inches in diameter and connected to the entrance hole by a short tunnel. The entrance hole is at the bottom or lower side of the nest. This is apparently effective protection against predators. A single nest can contain up to 12 nestlings, with the average being five to nine. Most nests are started by a single pair of birds. Over time, the nest is added to by other pairs of birds. It is thought that the additional nests are established by offspring of the original pair.
As students in Barnum Hall can attest, the parakeets are noisy. These social birds are constantly vocalizing with squawks and shrieks as they work. Studies have identified eleven different vocalizations with different meanings.
Many people are surpirsed that these parakeets can survive our harsh winters. However, though the birds are native to equitorial countries in South America, they come from mountainous areas. Also, their nests are well built to insulate them from the cold and enable them to keep warm with body heat.
