Description wikipedia

The red-rumped tinkerbird (Pogoniulus atroflavus) is a small bird species in the Lybiidae family. It is widely distributed across the tropical rainforests of mid-western Africa. This species is monotypic, with no recognized subspecies. Measuring approximately 12–13 cm in length and weighing 14–21.5 g, the Red-rumped Tinkerbird is noted for its distinct coloration—a yellow chest, black head and back, and red lower back or rump that gives the species its name. The wings are black with yellow-tipped feathers, and younger birds tend to display duller plumage with a yellowish bill.
