The Foraging And Habitat Ecology Of Black Terns In Maine, Andrew Gilbert
The Foraging And Habitat Ecology Of Black Terns In Maine, Andrew Gilbert
Electronic Theses and Dissertations
The population of Black Terns in Maine is small and factors related to the ecology of this species’ foraging and habitat ecology might limit population growth and recovery. The objectives were to (1) determine if diet and provisioning rates are limiting chick growth, (2) identify and rank suitable habitat in Maine, and (3) determine if precipitation patterns and water level dynamics are limiting in Maine. I compared growth rates of chicks in 1998-2000 in Maine to rates from other studies, determined the influence of colony, year, and diet on growth rates and food deliveries and used an energetics model to …
