How did you spend your Sunday afternoon in Stafford County, Va?




University of Mary Washington Professor of Biology Andrew Dolby is a behavioral ecologist and ornithologist and is an expert on avian behavior. His research areas include mixed-species flocking behavior and the evolution of bird song complexity. Recently, he has expanded his research program to include the biological effects of microplastics ingestion by ducks and geese, an increasingly prevalent, but understudied threat to waterfowl around the world. He is collaborating on this project with Drs. Tyler Frankel and Ben Kisila, both in the Department of Earth and Environmental Sciences.

A member of the American Ornithological Society and past president of the Virginia Society of Ornithology (VSO), Dr. Dolby teaches animal behavior, ecology, evolution and ornithology at Mary Washington. He also leads student field trips to Panama and the Galapagos Islands.

Dr. Dolby’s articles include publications in scientific journals such as Behavioral Ecology, The Auk (journal of the American Ornithological Society), Animal Behavior, and Journal of Field Ornithology.

Social context affects risk taking by a satellite species in a mixed-species foraging group

Behavioural Ecology


Mixed-species flocks of birds form during winter in the eastern deciduous forests of North America. These flocks consist of two flock-leading nuclear species, tufted titmouse (Baeolophus bicolor) and Carolina chickadee (Poecile carolinensis), and several follower, ...

Effects of winter weather on horizontal and vertical use of isolated forest fragments by bark-foraging birds



We examined how wind and temperature below the thermoneutral zone may reduce the suitability of small, isolated woodlots for permanent resident woodland birds. Carolina Chickadees (Poecile carolinensis) and Tufted Titmice (Baeolophus bicolor) exhibited ...

Social dominance and energy reserves in wintering woodland birds



To understand animals' tactics for surviving the winter season, we need to know how they manage their energy reserves. Fat reserves in small birds in winter generally increase with starvation risk. Studies have documented higher fat reserves in response to various ...

Functional roles in mixed-species foraging flocks: a field manipulation

The Auk


Mixed-species foraging flocks occur in a variety of habitats (Winterbottom 1949, Moynihan 1962, Mc-Clure 1967, Morse 1970, Greig-Smith 1978, Powell 1985, Eguchi et al. 1993), and participants in such flocks are thought to acquire foraging and predator avoidance ...

Benefits to satellite members in mixed-species foraging groups: an experimental analysis

Animal Behaviour


Hypotheses proposed to explain the formation of mixed-species foraging groups have focused on both foraging and antipredation benefits. Mixed-species flocks of bark-foraging birds form during the winter in the eastern deciduous forests of North America. These ...
