BRI wildlife research biologists, along with a wide range of collaborating scientists, conduct innovative wildlife science around the globe. Always at the forefront of our work is attention to the care of the wildlife we handle. Here, a biologist measures the beak of a Cooper's Hawk.

Top News and Events

Biodiversity Research Institute (BRI), a nonprofit ecological research group based in Portland, Maine, conducts innovative wildlife science worldwide.

BRI’s Center for Mercury Studies plays a lead scientific role in understanding the exposure and effects of mercury on wildlife in New England, North America, and around the world. The Center for Waterbird Studies is dedicated to assessing current and emerging threats to waterbirds. The programs in our Center for Ecology and Conservation Research aim to understand the workings of wildlife and their habitats while exploring how ecological stressors affect different species and ecosystems.

BRI's researchers are available to talk to journalists and provide expert information on both their work and the broader topics of their expertise.

BRI’s Live Webcam Captures Bald Eagle Laying an Egg

Gorham, ME – Biologists at Biodiversity Research Institute (BRI) confirmed today that the eagles being monitored by the webcam dubbed Eaglecam1, located in Hancock County, ME, are nesting. Overnight on March 14th, the female laid her first egg of this breeding season. The webcam, one of two cameras sponsored by Brookfield Renewable Energy Partners, captures the breeding activity of these raptors in real time.

Visitors to BRI’s website can watch the daily nesting activities of this pair of eagles in a live feed that is offered to the public free of charge.

“We are happy to support these eagle webcams because they provide a valuable educational resource for the public to observe nesting behavior,” says William Hanson, senior biologist for Brookfield.

“This is the third consecutive year that eagles have attempted to nest at this site and they were successful at raising one chick that fledged last year,” says Patrick Keenan, BRI’s outreach director and coordinator of the Institute’s webcam program. “We should expect an additional egg or two to be laid in the coming days and, if all goes well, the eggs will hatch in about 35 days.”

Eaglecam1, which was installed in February 2006, captured the successful nesting of a pair of eagles in the spring of that year—two young eagles, or nestlings, survived. In 2007, the pair again nested, but a three-day Nor’easter resulted in the loss of the chicks. Last year, the nesting pair at this site successfully raised one chick.

“It is very nice to see birds nesting reliably at this site. The recovery of Bald Eagle populations represents one of the great success stories of the Endangered Species Act and the collective efforts of many individuals and organizations,” says wildlife research biologist Christopher DeSorbo, director of BRI’s raptor program.

“These eagle webcams allow the general public a rare and intimate look into the inner sanctum of nesting eagles,” says Charlie Todd, Endangered and Threatened Species Coordinator for the Maine Department of Inland Fisheries and Wildlife (MDIFW). “The more we know about these birds, the better equipped we are to help protect them.”


Brookfield Renewable Energy Partners operates one of the largest publicly traded, pure-play renewable power platforms globally. Its portfolio is primarily hydroelectric and totals approximately 5,300 megawatts of installed capacity in Canada, the United States, and Brazil. The portfolio generates enough electricity from renewable resources to power two million homes on average each year. Brookfield is committed to understanding, minimizing, and managing the potential environmental impacts and public safety hazards associated with our operations and activities.

Additional support for BRI’s webcam program is provided by the Maine Department of Inland Fisheries and Wildlife (MDIFW) and the U.S. Fish and Wildlife Service (USFWS). The MDIFW is a state agency that oversees the conservation and responsible use of Maine’s natural resources.
