Nesting Wars

Monk parakeets that have returned to the wild are causing problems for utility companies.

Since 1970, New York City has been home to a different species of immigrant: the monk parakeet. Usually a common sight in pet stores, these birds started being spotted around the city and now Brooklyn is home to the largest population. For the residents, they are an exotic addition to the natural environment, but the utility companies have deemed them a nuisance since their huge nests, often built on electrical poles, can catch on fire or cause blackouts if they are built too close to a transformer. In some states, the problem is dealt with by killing the parakeets, but in New York, some people are trying to find a less drastic solution.

Dr Eleanor Miele, a professor of elementary science and environmental education at Brooklyn College, has been studying the monk parakeets in the area for the past seven years. They are native to Argentina and Brazil and she believes that the majority of these birds were introduced to the New York City environment when a shipment of parakeets being sent out of the country was accidentally released in 1967. A small percentage of the parakeets are former pets that escaped or were released and joined this main group. Parakeets typically live about 30 years and Miele claims that some of the birds now living around the college are from the original flock.

Although monk parakeets are small birds, on average 29 cm long, their nests are hard to miss. They can be quite monstrous, sometimes reaching the size of a small car and weighing up to 2,000 pounds. Parakeets are highly social and live in colonies where up to 200 couples can share the same nest with separate entrances for each pair. Each couple's "apartment" is quite sophisticated and contains an area for laying and incubating eggs, a living area for the hatched chicks and a lookout point for the parents to guard the nest. Among parrots, they are the only species to even make a nest since other species simply find a hole to lay and incubate their eggs.

It is obvious that the size and weight of parakeet nests can make them highly destructive. In Connecticut, monk parakeets are blamed for having caused about a dozen power outages per year and four fires in the past four years. In December 2005, United Illuminating, the electric power company, used nets to trap parakeets living in 103 nests on power poles and turned them over to the U.S. Department of Agriculture where they were gassed with carbon dioxide. In Brooklyn, Consolidated Edison is responsible for electric power and they have been removing the nests without capturing the birds. However, this has to be done periodically and isn't a permanent solution to the problem.
