Monk Parakeets: An Expanding Problem on Power Lines and Other Electrical Utility Structures

Abstract

This chapter describes the effects of monk parakeets to electric utilities and other economic sectors, monk parakeet basic biology, and short-term and long-term control and management strategies. Monk parakeets are an invasive species found throughout the United States. and their populations are expanding. In urban and suburban areas in Florida and other states, the monk parakeet nests on transmission lines, substations and distribution poles as well as other man-made structures and trees. As a stick building nester, its populations have grown exponentially in the last 10 to 15 years. Their nests on utility structures cause significant electrical reliability problems, increased operation and maintenance costs, and safety concerns. The monk parakeet is an invasive species that is banned in some states, e.g. California, but not in others, e.g. Florida. In the past, control of the monk parakeet involved shooting the birds. This was socially unacceptable and control measures stopped. Presently, the most effective short-term control strategy is capture of the birds and removal of the nest. Nest removal without capture of the birds only compounds the problem, as the parakeets will rebuild their nests. Long-term controls for the monk parakeet are not yet developed; however, a chemosterilant, Diazacon, shows promise.
