| Call of a northern red-billed hornbill | |
Tockus is a genus of birds in the hornbill family, Bucerotidae, that are native to Africa.
Taxonomy
[edit]The genus Tockus was introduced in 1830 by the French naturalist René Lesson. He listed three species in his new genus but did not specify a type species.[2] In 1840 the English zoologist George Gray selected the type as Buceros erythrorhynchus, the northern red-billed hornbill.[3][4] The genus name is derived from a word used by local people in Senegal for a hornbill.[5][6]
Description
[edit]Hornbills in the genus Tockus are medium-sized African birds with triangular shaped curved bills. They can be found in tropical and sub-tropical African grasslands, forests and savannahs. They all have long tail feathers which are black on the exterior and white on the interior.

[edit]The genus contains the following ten species:[7]
- Tanzanian red-billed hornbill, Tockus ruahae – central Tanzania

- Von der Decken's hornbill, Tockus deckeni – Ethiopia and Somalia to central Tanzania
