In 2007, the Committee on the Status of Endangered Wildlife in Canada ( COSEWIC) assessed the Chimney Swift as Threatened, indicating the species is likely to become endangered if nothing is done to reverse the factors causing declines.
The Chimney Swift was added to Schedule 1 of the Species at Risk Act (SARA) in 2009, giving it legal protection. It is also protected under the federal Migratory Birds Convention Act. These laws make it an offence to disturb, kill, or collect adults or their young, nests, or eggs.
In the United States, Chimney Swifts are protected under the Migratory Bird Treaty Act of 1918. However, outside of Canada and the U.S., there is no known protection for Chimney Swifts on their wintering grounds or during migration. Threats to Chimney Swifts in their winter range include intensive logging and burning of forests, and pesticide use.
