During my studies of primate behavioral ecology in the Kibale Forest, Uganda, I documented the first cases of red-capped robin-chats Cossypha natalensis imitating an antiphonal duet. In one case two individual robin chats imitated the entire duet of the black-faced rufous warbler Bathmocercus rufus, each giving both the male and female components. In a second case one robin chat gave the male components and another gave that of the female warbler. The lack of temporal separation between the male and female components of the warbler's antiphonal duet indicates an unusually high level of auditory perception and response time and cognitive ability on the part of redcapped robin-chats.

Uzungwa Scarp Forest Reserve (USFR) is one of the largest continuous forests within the Eastern Arc Mountains that has not been surveyed adequately from a herpetological perspective. A herpetological survey was carried out in the USFR at the beginning of the wet season, from December 2014 to February 2015. Bucket pitfall traps, night surveys and opportunistic search methods were conducted in six sites. Of 21 reptile species recorded during the survey, five are reported for the first time in the USFR. The checklist of reptiles for the area is updated from thirty three to thirty eight species. The study also provided notes on reproduction and extension in distribution for Xyelodontophis uluguruensis, a snake that was only discovered in 2002 and is known to be restricted to the Uluguru, Nguru and Mahenge mountains. These findings add to the conservation importance of the USFR and calls for more long term surveys especially in the least explored areas.

Three species of suids occur on the broad coastal plain of Kenya east and north of the Tana River; desert warthog Phacochoerus aethiopicus, common warthog Phacochoerus africanus, and bushpig Potamochoerus larvatus. Systematic cameratrap surveys, comprising 9229 camera-trap days on grids at six study sites, were used to determine the distribution and relative abundance of these three suids in the Boni-Dodori Forest Complex (ca. 4000 km²) and in Arabuko-Sokoke Forest Reserve (416 km²) on Kenya's north and central coasts, respectively. In the Boni-Dodori Forest Complex, desert warthog was captured at one camera site, common warthog at four camera sites, and bushpig at 33 camera sites. In Arabuko-Sokoke Forest Reserve, only bushpig was captured (seven camera sites). Sympatry of desert warthog and common warthog seems limited in the Boni-Dodori Forest Complex. Here, desert warthog appears to be narrowly sympatric with bushpig whereas common warthog is broadly sympatric with bushpig. Sympatry of the three suids in this region was not previously reported. This sympatry is absent in Arabuko-Sokoke Forest Reserve.
