Parasitic Jaeger
Stercorarius parasiticusAlso known as Arctic Skua, Parasitic Skua, Arctic Jaeger
Parasitic Jaegers are agile aerial acrobats of the high northern latitudes, known for relentlessly chasing gulls and terns to steal their freshly caught fish. On their tundra breeding grounds, adults nest directly on open ground and fiercely defend their eggs with dramatic injury-feigning displays and swooping aerial dives. During migration and winter, they roam wide open oceans across the southern hemisphere, leading mostly solitary lives offshore.

Interaction riskLow
- Low
- Moderate
- High
- Very high
- Why interaction risk is low
- Nesting birds fiercely dive-bomb intruders; maintain a safe distance during the breeding season.
- What to notice
- Medium-sized dark or light-morph seabird with pointed central tail feathers and white wing flashes.
- Support conservation
- Keep a distance from tundra nesting territories, leaving immediately if adults swoop or dive-bomb.
Responsible observation
- Observation: Scan offshore seabird flocks or coastal roosts with a spotting scope during migration.
- Breeding Caution: Give nesting tundra pairs a wide berth if they begin alarm calls or diving displays.
