Estrilda troglodytes
A grey-brown finch with a red bill and red eye-stripe, named for its black rump and tail. Exceptionally hardy and easily tamed, it has been imported into Japan as a cage bird since the 1960s.
The black-rumped waxbill (Estrilda troglodytes) is an estrildid finch of the savanna and steppe belt of West and Central Africa. The bill and eye-stripe are red and the rump is black. The sexes are hardly separable, the female being marginally paler, and no subspecies are recognised. It resembles the common waxbill but is less sharply marked and rather smaller. Lichtenstein described it in 1823 in the genus Fringilla, and it was moved when Estrilda was erected in 1850. It has been brought into Japan as a cage bird since the 1960s, with breeding recorded in Tokyo and sightings in Osaka and Saitama. It withstands capture, transport and acclimatisation exceptionally well, which is why Europe long relied on imports rather than captive breeding.
