摘要：The range of the Silvery-cheeked Hornbill Bycanistes brevis is almost entirely east of the Rift Valley from the Ndotos and the Mathews Range, south through the Mt Kenya and Aberdare highlands to Thika, Nairobi, Kibwezi, Ol Donyo Orok (Namanga Hill), the Chyulus, and Taita-Taveta District, including the Taita Hills forests. It also occurs in coastal forests from the Arabuko-Sokoke and Gede forest reserves south to the Shimba Hills, Mrima Hill, and Shimoni forests. Meanwhile, wanderers from north- ern Tanzania appear seasonally in the Nguruman and Loliondo forests astride the Kenya–Tanzania border. It occurs alongside Trumpeter Hornbill Bycanistes bucinator in some inland areas and most coastal forests south of Malindi including the Arabu- ko-Sokoke Forest Reserve.
