Crithagra rothschildi (Serinus rothschildi)
Geographical distribution and habitat
The Olive-rumped seedeater belongs to the somewhat smaller species with no striking colors and markings. Crithagra rothschildi is observed in the highlands of Saudi Arabia and parts of Yemen. This Crithagra species from the Middle East is seen in cultivated areas and in open, rocky areas with scarce vegetation. It has been observed that they take vegetarian food (mainly seeds). Although there is also mention of them being observed eating insects, but this is probably applicable for most all Serin species. They find their food on, or low to the ground.
Size: 12 cm (4.7 inch)
Description and subspecies
Sexes alike, there is no difference in appearance in male or female. The males would be a little more clear on the chest and belly and a little more clear strikes. No subspecies mentioned.
In terms of taxonomy, the Olive-rumped seedeater is somewhat confusing. There are experts who assume that Crithagra rothschildi, with its dark olive-green rump, is a subspecies of Crithagra atrogularis, (Black-throated canary). Others see these birds as a subspecies of Crithagra xanthopygia (Yellow-rumped canary), who lives in an area more close by than the Black-throated canary. There are also opinions that consider Crithagra rothschildi and Crithagra menachensis (Yemen serin) as species and subspecies. The fact is that both bird species are found outside the African continent, in a separate area and strongly resemble each other. It is not known whether the Olive-rumped seedeater was ever introduced in European aviculture. The beak of these birds is quite substantial for this, relatively small bird.
