Cinnamon-chested Bee-eater

The cinnamon-chested bee-eater (Merops oreobates) is a colorful, aerial insectivore in the family Meropidae, endemic to the highlands of East Africa. It is found in Uganda, Kenya, Tanzania, Rwanda, Burundi, and eastern DRC, typically at elevations between 1,500 and 3,000 meters in montane forest edge, woodland clearings, and cultivated areas with tall trees. Like all bee-eaters, it is a masterful aerial hunter, catching bees, wasps, and other flying insects in fast pursuit flights from open perches. The plumage is brilliant—green upperparts, a bright blue rump and undertail, a distinctive cinnamon-rufous chest, and a black gorget separating the throat from the breast. The species is classified as Least Concern by the IUCN, with stable populations across the East African highlands. It often nests colonially, digging burrows into earthen banks or flat ground. The cinnamon-chested bee-eater is absent from Europe; Norwegian database records are data entry errors. This bee-eater is a popular species with birdwatchers visiting the East African highlands, often observed conspicuously from perches at forest edges. Conservation of highland forest and woodland habitats, and the retention of earthen banks for nesting, are beneficial for this species.
