A striking and highly localized seabird found only in the Chatham Islands of New Zealand, with its main stronghold on Pitt Island and nearby rocky islets. This limited range makes it one of the world’s most geographically restricted shags, adding to its uniqueness and vulnerability. Medium-sized and robust, the Pitt Island shag has a strong, heavy bill, a thick neck, and a powerful body well-suited for diving. Its plumage is mostly dark, with contrasting white patches on the face and neck that give it a bold and distinctive appearance, especially during the breeding season.

One of the most noticeable characteristics of the Pitt Island shag is its strong connection to the sea. It is an expert diver, using its webbed feet to propel itself underwater in search of fish. Unlike birds that rely on speed alone, this shag uses controlled, powerful strokes to chase prey beneath the surface. It typically forages close to shore, diving in shallow coastal waters where fish are abundant. After fishing, it is often seen perched on rocks with its wings spread wide, a classic shag behavior that helps dry its feathers after repeated dives.

What sets the Pitt Island shag apart from other shags is not only its restricted range but also its subtle differences in appearance and behavior. Its facial markings are more pronounced than those of many related species, and its breeding plumage gives it a particularly striking look. Because it lives in such a confined area, it has adapted closely to local conditions, including water temperature, prey availability, and weather patterns.
