Biographical Summary of Contractors

Jennifer J. Barg graduated with an M.Sc. in 2002 from Queen’s University, Kingston, ON. Over the last 10 years, Ms. Barg has worked extensively with migratory birds, specifically wood-warblers. She was a member of Richard Holmes’ research group at Dartmouth College working on Black-throated Blue Warblers at the Hubbard Brook Experimental Forest in the White Mountains of New Hampshire for 6 years. This work entailed research both on the breeding grounds and on the wintering grounds in Jamaica. For her M.Sc. research, Barg focused on within-territory spatial and habitat use patterns of male Cerulean Warblers and their behavioural counterparts.

Jason Jones received his Ph.D. in 2000 from Queen’s University. His dissertation focused on habitat selection and conservation ecology of Cerulean Warblers in eastern Ontario. He currently holds the position of Croasdale Fellow in Vertebrate Biology in the Department of Biological Sciences at Dartmouth College, Hanover, New Hampshire.

Raleigh J. Robertson is a Professor of Biology at Queen’s University and is the Director of the Queen’s University Biological Station. He has recently been named as the first holder of the Baillie Family Chair in Conservation Biology at Queen’s.
