Hall's babbler

Hall's babbler is a small species of bird in the family Pomatostomidae most commonly found in dry Acacia scrubland in interior regions of eastern Australia. Superficially similar to the white-browed babbler this species was only recognised during the 1960s, which makes it a comparatively recent discovery. The bird is named after the Australian-born philanthropist Major Harold Wesley Hall, who funded a series of expeditions to collect specimens for the British Museum, during which the first specimens of Hall's babbler were collected in southwestern Queensland in 1963.

Halmahera boobook

The Halmahera boobook is a species of owl in the family Strigidae. It inhabits the Indonesian islands of Halmahera, Ternate and Bacan.

Hamerkop

The hamerkop, also called the umbrette, is a medium-sized bird. It is the only living species in the genus Scopus and the family Scopidae. The species and family was long thought to sit with the Ciconiiformes but is now placed with the Pelecaniformes, and its closest relatives are thought to be the pelicans and the shoebill. The shape of its head with a long bill and crest at the back is reminiscent of a hammer, which has given this species its name after the Afrikaans word for hammerhead. It is a medium-sized waterbird with brown plumage. It is found in mainland Africa, Madagascar and Arabia, living in a wide variety of wetlands, including estuaries, lakesides, fish ponds, riverbanks, and rocky coasts. The hamerkop is a sedentary bird that often shows local movements.
