Lake Ol’ Bolossat is an inland wetland located in Nyandarua County, Kenya that provides critical year-round habitat for the Globally Endangered Grey Crowned Crane Balearica regulorum gibbericeps. This study aimed at establishing the population size and density of cranes in the basin, ratio of young to adults (as a measure of productivity), and habitat selection and use during the breeding and non-breeding seasons. Using complete ground counts, five censuses were conducted between 2017 and 2020 with between 521 and 1115 cranes recorded, and we estimate the local population size to be 250–350 individuals. Population density ranged from 0.99–2.18 cranes/km² during the breeding and non-breeding seasons respectively. From all 219 observations made during the study period, the mean flock size was 28.21 with a maximum flock size of 332 and a modal flock size of 2–25 individuals. The average proportion of young cranes across all counts was 11.65% indicating a population which is breeding successfully. Although cranes occupied both wetlands and terrestrial habitats in almost equal proportions across the year cumulatively, the difference in choice of habitat between the breeding and the non-breeding seasons was significant (χ² = 489, df = 1, p = 0.0001), whereby more cranes (mostly paired individuals) were observed in marshes during breeding months. Wheat fields were the most often used of terrestrial habitats among fields of different crop types sampled. Holding 14% and 5% of Kenya’s and the global population of Grey Crowned Cranes, respectively, Lake Ol’ Bolossat is undoubtedly an important site for this species’ conservation and survival.

The Red-capped Lark Calandrella cinerea inhabits some of the most highly threatened grassland ecosystems in Kenya. Although previous studies have been undertaken on feeding ecology of this species, a knowledge gap still exists in relation to its nest food provisioning behaviour. We studied the food provisioning behaviour of Red-capped Larks in open grassland habitat at Kedong Ranch in Naivasha, Kenya. Observations were completed on 18 active nests for a total of 163 observation hours between 07:00 and 18:00. Results confirmed that nestling diet comprised insect larvae (including caterpillars), grasshoppers, butterflies/moths, ants and beetles. Food provisioning rates for males and females combined, as well as independently, did not vary with the nestling age. In relation to specific prey items, provisioning rates of insect larvae and butterflies/moths during different hours of the day did not vary. However, there was a significant difference in provisioning rates of grasshoppers for the time periods. The findings provide an understanding of food requirements and feeding behaviour of the Red-capped Lark, and therefore are important for predicting how future changes in the availability of food resources could influence feeding, reproductive success, and possibly survival of the species.

The article focuses on the status of the undocumented the Grey-chested Babbler (Kakamega poliothorax) in Kenya. Topics discussed include the biodiversity survey expeditions conducted in the country, the bird retrapping, and the K. poliothorax specimens for Museum collection. The article also discusses the regular monitoring of birds around the Ikuywa river area of Kakamega Forest.
