The long-tailed skua is the smallest and most elegant of its kind. It is built for speed and endurance. The body is slender. The wings are long and pointed. The tail extends well past the wingtips in flight. Central tail feathers are elongated, streaming behind like ribbons. It looks like a skua designed by someone who prioritised grace over aggression. This visual distinction sets it apart from its bulkier relatives.
In breeding plumage, the head and breast are dark grey. The belly is white. The back is grey. The cap is black. The bill is dark. The bird is handsome in a quiet way. Outside the breeding season, it becomes paler and streakier. It is less distinct. Identification requires attention to detail. The tail streamers are the key. They define the species.
Feeding habits shift with location. On the tundra, it is a rodent specialist. It targets lemmings and insects. Hunting involves hovering, then dropping onto prey. It is efficient. It is patient. At sea, it becomes a pirate. It chases terns and kittiwakes, forcing them to drop their catch. The skua catches the food midair. No thanks offered. No apology given. Kleptoparasitism is a valid strategy. It saves energy. The diet also includes fish and carrion when available.
Flight is buoyant and tern-like, with rapid wingbeats and long glides. In a storm, the long-tailed skua is in its element. It rides the wind, tilting from one gust to the next. It uses the chaos. Stability is not required. The call is a harsh, chattering "kee-kee-kee," often given in flight. It sounds like a warning. It is. The sound marks the presence of the bird. It signals aggression or alarm.
In New Zealand, these birds are rare visitors. Most records come from offshore waters. The Tasman Sea and the east coast of the North Island host occasional sightings. Birds have crossed from the Northern Hemisphere. They follow the same migration route as the
Arctic tern. The long-tailed skua breeds in the Arctic, from Alaska to Russia. It winters in the Southern Ocean, off South Africa and South America. It crosses the equator twice a year. It does not seem to notice. The journey is routine.
The population is stable globally. The long-tailed skua is not endangered. It is just rare here. Climate change affects Arctic breeding habitat and lemming populations. Incidental bycatch in fishing gear poses a risk. Pollution at sea adds another layer of pressure. But the global numbers remain healthy. Estimates suggest 500,000 to 1,000,000 birds. In New Zealand, it remains a rare visitor to offshore waters. Most commonly seen from the North Island coast. The long-tailed skua is the most graceful of the skuas. It is also the least aggressive. It prefers to steal food rather than fight for it. A pragmatic approach. It carries on.
