Estimated Wild Population
Hamerkops have monochromatic brown plumage with hints of iridescent purple. These wading birds have a darkly colored, long, flat bill that is slightly hooked at the tip. They use their sturdy bill to catch fish, frogs, rodents, and other small animals.
Interesting Fact 1
Hamerkops build relatively large nests that can support the weight of an adult human.
Interesting Fact 2
They were named for their distinctive head, which combines a thick bill in the front and a pointed wedge of feathers in the back.
Interesting Fact 3
They perform "false mounting," where one bird stands on top of another to display dominance without engaging in copulation.
