The Long-tailed Jaeger primarily feed its chicks with lemmings, and may skip breeding in years when lemmings are scarce. Its namesake feature is formed by two central feathers which extend far beyond the rest of the tail, however these feathers are generally only present in the breeding season.

The Long-tailed Jaeger breeds widely across the Canadian Arctic and winters at sea in the Southern Hemisphere. Migrants are observed regularly off British Columbia between May and early November, and less frequently in eastern Canada during fall migration. Based on distribution of records and global abundance estimates, slightly over 20% of the global total of 1.7 million individuals likely breeds in Canada, representing a moderate level of jurisdictional responsibility. Data are currently insufficient to estimate trends or set a goal for the Canadian population.
