The half-collared kingfisher (Alcedo semitorquata) is a kingfisher in the subfamily Alcedininae that is found in southern and eastern Africa. It feeds almost exclusively on fish and frequents streams, rivers and larger bodies of water with dense shoreline vegetation.
The half-collared kingfisher was described by the English ornithologist William John Swainson in 1823 and given its current binomial name Alcedo semitorquata. The word Alcedo is the Latin for a "kingfisher". The specific epithet semitorquata is from the Latin semi- for "half" or "small" and torquatus for "collared". The blue-eared kingfisher is one of seven species in the genus Alcedo and is most closely related to the shining-blue kingfisher (Alcedo quadribrachys).
It is known to sometimes vocalize while approaching its nest, but the purpose or advantage of this behavior is unclear.
