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 research on bird migration was recently published in the journal Global Ecology and Biogeography. The article, Large birds travel farther in homogeneous environments, compiled GPS tracking data from dozens of ornithologists around the globe to better understand how environmental factors (i.e., resource availability and arrangement) and other factors (i.e., taxonomy, body mass, diet, flight type, migratory status) affected bird movement patterns on the landscape at a global scale. The study found that bird movements were seven times longer in environments where resources were evenly distributed (i.e., homeogeneous) as compared to areas where resources were more variably distributed. This finding suggests that birds need to travel longer distances in homogeneous environments to meet their ecological needs, and that increasing global trends of habitat homogenization (i.e., intensification of agriculture) in some areas may have negative consequences for bird populations.
