The Auckland shag (Leucocarbo colensoi), also called the Auckland Islands shag, is a type of cormorant bird. It lives only in the Auckland Islands archipelago, which is a group of islands belonging to New Zealand. This bird stays in one place and does not migrate. It mainly eats small sea creatures called crustaceans and different kinds of fish.
Scientists have counted about 1,000 pairs of Auckland shags in recent years. These birds like to nest together in groups, building large nests from things like grass, twigs, and seaweed. They usually lay three pale blue-green eggs between November and February. The eggs hatch after about 26 to 32 days.

About the Auckland Shag
The Auckland shag is a special bird because it only lives in the Auckland Islands. This means it is endemic to these islands. Being endemic means a species is found only in one specific place in the world.
What They Eat
Auckland shags are excellent divers and hunters in the water. Their main diet includes:
- Various crustaceans, which are like small crabs or shrimp.
- Different types of fish found in the waters around the Auckland Islands.
They use their strong beaks to catch their food underwater.
Where They Live
The Auckland Islands are a remote group of islands in the Southern Ocean. They are known for their wild and natural environment. The Auckland shag finds all it needs to survive in this unique island home.
Reproduction and Life Cycle
Auckland shags are known as colonial nesters. This means many pairs build their nests close to each other, forming a colony. This can help them protect their young from predators.
Nesting Habits
- They build large nests using materials found nearby, such as grass, small branches (twigs), and seaweed.
- Nesting season is from November to February.
- Each female typically lays three eggs. The eggs are a pretty pale blue-green color.
Incubation and Chicks
- The parents take turns sitting on the eggs to keep them warm. This is called incubation.
- The incubation period lasts for about 26 to 32 days.
- After the chicks hatch, both parents work together to feed and care for them until they are old enough to fly and find their own food.
Conservation Status
The International Union for the Conservation of Nature (IUCN) says the Auckland shag is a Vulnerable species. This means it is at risk of becoming endangered if its population continues to decline.
Why They Are Vulnerable
- Small Population: There are only about 2,000 Auckland shags left in the world.
- Limited Home: They live in a very small area, only on the Auckland Islands. If something bad happens in that area, it could affect all of them.
Because of their small numbers and limited habitat, it's very important to protect these unique birds.
Scientific Names
Scientists sometimes disagree about how to classify animals. Some groups, like the International Ornithologists' Union, place the Auckland shag in the genus Leucocarbo. Other scientists put it in the genus Phalacrocorax. Both names refer to the same bird.
The scientific name of this bird, colensoi, was chosen to honor a naturalist named William Colenso. A naturalist is a person who studies nature, especially plants and animals.
