I am currently retired and am not supervising any more graduate students. I am still publishing research on demography of ptarmigan and American redstarts and, in collaboration with former students, effects of new forestry practices on cavity nesting species. My primary focus now is on active conservation in Garry Oak and coastal Douglas Fir ecosystems in British Columbia. My former research focused on costs/benefits for birds living in patchy habitats at the patch and landscape scales and on reproductive success of birds in agricultural and logged areas, the role of corridors for bird movements, and bird responses to habitat edges.
Work using video cameras has identified the following accipiters depredating American Redstart nests:
