Habitat and Distribution
The Olivaceous Cormorant is commonly found in wetlands, lagoons, estuaries, rivers, and lakes across much of South America. Its range extends through the Amazon basin, the Andes foothills, and coastal regions, where it often shares territory with other cormorant species. It prefers shallow waters where small fish are abundant and often roosts in colonies near water bodies.
Behavior and Diet
This species primarily feeds on fish, amphibians, and aquatic invertebrates. It dives skillfully, using its strong legs to chase prey underwater. After hunting, it is frequently seen perched with wings spread, drying its plumage in the sun. Colonies are formed in trees, reeds, or rocky islands, and their noisy gatherings can be spotted from a distance.
23. Little Black Cormorant
The Little Black Cormorant (Phalacrocorax sulcirostris) is a small, glossy-black waterbird commonly found across Australia, New Zealand, Indonesia, and nearby regions. It is one of the most social of all cormorants, often seen in large flocks that dive and feed together. Its slim build and dark plumage distinguish it from larger cormorants, making it highly recognizable in its range.
Identification
- Family: Phalacrocoracidae
- Length: 60–65 cm
- Wingspan: Around 100 cm
- Plumage: Glossy black overall, with a greenish sheen in bright light
- Bill: Long, slender, and dark gray with a hooked tip
- Eye: Striking turquoise-green, especially visible during breeding season
- Other Feature: Slender body and long neck, well adapted for underwater pursuit of prey
Habitat and Distribution
This species inhabits freshwater rivers, lakes, wetlands, and coastal lagoons. It is especially abundant in Australia, where it forms huge flocks in inland wetlands after flooding events. The Little Black Cormorant is also found across Southeast Asia and parts of New Zealand, preferring shallow, fish-rich waters.
Behavior and Diet
The Little Black Cormorant is known for its cooperative feeding behavior. Large groups dive together, herding fish into tight schools for easier capture. Its diet consists mainly of small fish, aquatic insects, and crustaceans. Like other cormorants, it often perches with wings outstretched to dry after diving. Colonies are typically formed in trees or reed beds near water, where hundreds of individuals may gather.
