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.

Common Fat-tailed Mouse Opossum

The Common Fat-tailed Mouse Opossum (<em>Thylamys pusillus</em>) is a small marsupial belonging to the genus Thylamys within the family Didelphidae. Like other members of its genus, this species typically stores fat in its tail, which becomes swollen during periods of food abundance and is metabolised during leaner times, a physiological adaptation that provides energy reserves. <em>Thylamys pusillus</em> is generally found in diverse terrestrial and aquatic ecosystems, often in dry woodlands, scrublands, and grassland habitats of South America. The species is assessed as Least Concern on the IUCN Red List, indicating it is not currently considered at risk of extinction. Detailed geographic range data are not available in the current record, but members of this genus are typically distributed across parts of Argentina, Bolivia, Paraguay, and Uruguay. Biological traits including average lifespan, body dimensions, and specific dietary composition remain poorly documented in the scientific literature, though Thylamys species are generally considered omnivorous, often consuming insects, small vertebrates, and plant material.
