What is the Eastern Loggerhead Shrike Recovery Program? After a precipitous drop in the wild eastern loggerhead shrike population in the 1990s, Environment Canada invited Wildlife Preservation Canada to join the multi-partner recovery effort in 2001. Since then, the wild population size has fluctuated. Studies have shown that although the recovery effort has prevented the species from disappearing from Canada, more work is required to identify and address the causes of the species’ decline. WPC works to prevent the endangered eastern loggerhead shrike from disappearing by building the wild population in Ontario, and studying the species to learn more about the threats they face.⁠
