The Parasitic Jaeger is an effective hunter and scavenger of mammals and other birds during summer, but at sea this species lives up to its name by using its speed and agility to harass other birds until they drop their prey.

Data Deficient
The Parasitic Jaeger breeds widely across the Canadian Arctic and winters primarily off the Pacific and Atlantic coasts of South America, with smaller numbers as far north as the United States. Based on distribution of records and global abundance estimates, slightly over one-third of the global total of 3.5 million individuals likely breeds in Canada, representing a moderate level of responsibility. Data are currently insufficient to estimate trends or set a goal for the Canadian population.
