Massive Common Nighthawk Decline in Canada

In April of 2007, the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) recommended that the Common Nighthawk Chordeiles minor be included on Schedule 1 of the Species at Risk Act. Areas surveyed over the last three generations have shown an almost 50 percent decline in the species! Reasons for its decline may include reductions in the number of insects and loss of the open habitat in which it thrives.
