ospreys were virtually wiped out in vermont and most of the united states by pesticides decades ago. ddt got into the food chain, and osprey populations plummeted as the chemical made their eggshells thin and brittle. central vermont public service has worked on osprey restoration efforts with the state for over 15 years, installing platforms at hydroelectric facilities, creating buffer zones and educating vermonters on the birds' need for space. a platform is under consideration at lake bomoseen. there have been occasional osprey sightings on lake bomoseen over the last few years.
