Hamerkop

Scopus umbretta

The Hamerkop (Scopus umbretta), a medium-sized wading bird, is the sole representative of its genus and family. Its distinctive hammer-shaped head, complete with a long bill and a rear crest, has inspired its name from the Afrikaans term for "hammerhead." Exhibiting a uniform brown plumage, this bird is a familiar sight across Africa, Madagascar, and parts of Arabia.

Identification Tips

Adult Hamerkops are characterized by their brown plumage with a subtle purple sheen on the back. The tail features faint barring of a darker brown. Both sexes appear similar, and juveniles resemble the adults. The bill, long and slightly hooked, is particularly compressed and thin, especially towards the lower mandible. Initially brown in young birds, the bill darkens to black upon fledging.

Habitat

Hamerkops are found in a plethora of wetland habitats, ranging from estuaries, lakesides, and fish ponds to riverbanks and rocky coasts. They have also adapted to human-altered environments, often seen in villages and agricultural areas.

Distribution

This species is widespread across sub-Saharan Africa, Madagascar, and coastal southwestern Arabia. It is generally sedentary, with some local movements observed.

Behaviour

Active predominantly during daylight, Hamerkops may rest during the midday heat and exhibit some crepuscular activity. They are known for their peculiar jerky walk, with their head and neck moving in sync with each step.

Song & Calls

When solitary, the Hamerkop is relatively quiet, save for a shrill flight-call. In contrast, when in groups, it becomes more vocal, producing a variety of cackles and nasal rattles. The "yip-purr" call is a notable social vocalization, often accompanied by wing flapping.

Breeding

Hamerkops are renowned for their massive nests, which are sturdy enough to support a human's weight. These nests, built by both parents, feature an internal chamber for egg-laying and are often constructed in tree forks or on human structures. Both parents share incubation duties and chick rearing.

Similar Species

The Hamerkop can be confused with young storks or herons due to its size and shape, but its unique head shape and behavior are distinctive.

Diet and Feeding

A generalist feeder, the Hamerkop's diet includes fish, amphibians, shrimps, insects, and occasionally rodents. It hunts in shallow waters, using both sight and touch, and is known to be adaptable in its feeding strategies.

Conservation status

The Hamerkop is classified as Least Concern by the IUCN, with a stable population trend and widespread local abundance in its range.

Learning Birding with Birda
I’m relatively new to birding as a hobby, and Birda is a great way to keep track off all the species I see. I’m still working on my ID skills, but the app is great for figuring out potential species, and the online community is so friendly and helpful. Definitely recommend Birda to both early and serious birders! 🐦
