This species is restricted to forested habitats in equatorial Africa, with Kenya at the eastern limit of the species’ distribution (Butynski et al., 2012; Ray & Butynski, 2013). The status of C. aurata in Kenya remains unknown. Until now, the only confirmed records are two skins collected by A. Toschi in 1946 from Ogiek tribesmen in the Mau Forest (Toschi, 1946; Butynski et al., 2012). One of the skins (Accession No. 3369/332A) is currently at the National Museums of Kenya (NMK). All other records from the country are sight records that lack a supporting photograph or specimen (Butynski et al., 2012). On 19 May 2019, a dead cat, presumably killed by a vehicle, was found beside the section of the Kamae-Thika road that bisects the Kieni Forest Reserve in the southern Aberdares (0°52'12.9144\"S and 36°45'05.4684\"E; figure 1). It was immediately identified as a possible C. aurata and taken to NMK (Accession No. NMK-MAM-192942). Upon inspection of the specimen, and in consultation with experts in the field (L. Bahaa-el-din (pers. comm.); T.M. Butynski (pers. comm,); D. Mills (pers. comm.)), the specimen was confirmed to be a C. aurata. This is the first confirmed record of C. aurata for Kenya since 1946, and the first record of this species east of the Eastern Rift Valley. This specimen was collected ~2300 m above sea level in Afromontane forest at the edge of the bamboo zone. It was a female of the golden/reddish-brown morph (Bahaa-el-din et al., 2015a; figure 2) with the following weight and body measurements: weight: 3.1 kg, headbody length: 60 cm, and tail length: 26.5 cm.

The former was captured in association with its host, Nomioides (Nomioides) turanicus (Halictinae: Nomioidini). Chiasmognathus saheliensis is considered a new junior synonym of Pasites gnomus, and the latter epithet is transferred to Chiasmognathus: C. gnomus.

Systematic camera trap surveys, comprising 9229 camera trap days on grids at six study sites, were used to determine the distribution and relative abundance of the Sokoke bushy-tailed mongoose in the two largest Kenyan coastal forests: Boni-Dodori Forest Complex (ca. 4000 km2); and Arabuko-Sokoke Forest Reserve (416 km2). This species was captured in all surveyed forests with significantly more detections in Brachystegia woodland habitat (ca. 71 km2) of Arabuko-Sokoke and the Boni forest sectors (ca. 2000 km2) of the Boni-Dodori Forest Complex. Boni-Dodori Forest Complex, with an estimated occupancy of over 60% for this species, holds a significant population. The study generated over 1000 images of the Sokoke bushy-tailed mongoose in a total surveyed area of approximately 500 km2 providing the first 24-hour activity data for the species. The circadian patterns confirm this species to be strictly nocturnal. This study strongly recommends that its Red List status remains ‘Vulnerable’. The few remaining coastal forests continue to face human pressure. Recent proposals to find and extract hydrocarbons from under the Arabuko-Sokoke Forest, and the planned major development close to Boni-Dodori Forest Complex, raise serious conservation concerns for this exceptionally biodiverse ecosystem.","PeriodicalId":143820,"journal":{"name":"Journal of East African Natural History","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125146389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Porcupine quills can be effective weapons and sometimes seriously wound lions, resulting in death. Death from quills can be a slow process and under these circumstances, death may be the result of starvation or infection (septicaemia).","PeriodicalId":143820,"journal":{"name":"Journal of East African Natural History","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128182783","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Few long-term behavioural studies have been conducted on African nocturnal primates. Here we describe and compare behavioural and ecological observations on two species of pottos (Perodicticus ibeanus and P. edwardsi) across ten sites. We observed a total of 51 P. edwardsi and 28 P. ibeanus. We recorded all 21 postures within an established lorisid ethogram, as well as 42 of 50 behaviours. Eating, locomotion, freezing, resting and sniffing were the most common behaviours. We recorded behaviours not previously described for perodicticines, including bark chewing and unique vocalisations. Three species of pottos are now recognised, with potentially more species to be revealed within this cryptic and nocturnal genus. Although there are similarities among potto species, we show that unique ecological adaptations and behaviours may further elucidate their diversity.","PeriodicalId":143820,"journal":{"name":"Journal of East African Natural History","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126806663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mean length of time between discovery of rat remains in any one owl territory was once every 5.3 months, and the maximum number of rats found in any single owl territory over one year was five. Maned rat density was low and was estimated at 1 rat/km2. Their lower altitudinal limit in Kenya is c. 1900 m, and eagle owls and humans are important predators.

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.
