Species At Risk

Bicknell's Thrush (photo by Hubert Askanas).Populations of species recognised to be at risk from environmental change – particularly change due to human activities – require particular attention. Often they cannot be investigated in as much detail as might be possible with non-threatened species. We have been studying Bicknell's Thrush (Catharus bicknelli) in northern New Brunswick for several years, with projects by Hubert Askanas, Emily McKinnon, and Chris Ward.

lsewhere, Kevin Mahabir has completed a study on the endemic Barbuda Warbler (Setophaga subita)in the West Indies; and Mark MacDonald's Master's research on sexing Nihoa Millerbirds (Acrocephalus familiaris kingi) in the field, including verifying that Laysan Island would provide adequate resources for a translocated population, provided crucial evidence to support the subsequent translocations by U.S. conservation agencies of this critically endangered bird from Nihoa to Laysan Island in Hawaii.
