The Hawaiian Coot is a medium-sized bird, with a body length of about 14 inches and a wingspan of about 22 inches. It has a distinctive appearance, with a black head, neck, and chest, a white bill, and a black body with a white underside.

Diet

The Hawaiian Coot is an omnivorous bird, meaning it feeds on a wide range of plant and animal matter. Its diet includes a variety of aquatic plants, seeds, fruits, insects, snails, worms, and small fish. The Hawaiian Coot forages for food in the water or on land, using its strong bill to dig for food or to sweep the water for small aquatic animals.

In the wetland habitats where the Hawaiian Coot is found, it is an important seed disperser, helping to spread the seeds of aquatic plants and other wetland vegetation. This helps to maintain the diversity and health of these habitats, which are important for a wide range of species.

Behavior

Hawaiian Coot is a fascinating and unique bird that plays an important role in the wetland ecosystems of the Hawaiian Islands. It is a social bird and is often found in groups or flocks, which can range in size from a few individuals to several hundred birds.

The Hawaiian Coot is a strong swimmer and is often seen swimming or diving in the water to forage for food. It is also a strong flier, and may fly short distances to move between different wetland habitats or to escape predators.

It is known to be territorial and will defend its territory against other birds, particularly during the breeding season. It may engage in aggressive behavior, such as pecking or chasing, to defend its territory or protect its young.

In addition to its territorial behavior, the Hawaiian Coot is also known to engage in courtship displays, such as head-bobbing and vocalizations, to attract a mate. The male and female work together to build the nest and care for the young, with both parents bringing food to the chicks and protecting them from predators.

Nesting

The Hawaiian Coot is a non-migratory bird and breeds throughout the year in the Hawaiian Islands. It typically nests in wetlands, marshes, and other wetland habitats, often building its nest on a small island or floating platform within a wetland.

The female Hawaiian Coot builds the nest, which is made of grasses, reeds, and other plant materials and is lined with feathers. The nest is typically cup-shaped and is built on the ground or slightly above the water level. The female lays a clutch of 3-9 eggs, which are incubated by both the male and female for about 21-25 days.

The Hawaiian Coot is known to be a cooperative breeder, meaning that non-breeding individuals may help to care for the young. This helps to increase the survival rate of the chicks and may also increase the overall reproductive success of the group.

Habitat

The Hawaiian coot is adapted to living in a variety of wetland habitats, including freshwater marshes, estuaries, and coastal lagoons. It is typically found in shallow water and is able to swim and dive to feed on a variety of aquatic plants and animals, such as algae, snails, and insects.

Range in Hawaii

The Hawaiian Coot is a non-migratory bird and is found throughout the main Hawaiian Islands, including Kauai, Oahu, Molokai, Lanai, Maui, and Hawaii.

Conservation Status

The Hawaiian coot is listed as vulnerable due to a combination of factors including habitat loss, habitat degradation, and the introduction of non-native species. These factors have led to a decline in the population of the species, and it is considered to be at risk of extinction.

Conservation efforts for the Hawaiian coot in Hawaii include habitat protection, habitat restoration, and the control of non-native species. These efforts are important for the preservation of Hawaii’s unique ecosystems and the species that depend on them.
