Bokmakierie

It is a species of open habitats, including karoo scrub, fynbos and parks and gardens in urban areas. The bulky cup nest is constructed in a hedge, scrub or tree fork. The 2–6, usually three, red-brown or lilac-blotched greenish-blue eggs are incubated by both sexes for about 16 days to hatching, with another 18 days to fledging.

The adult bokmakierie is a 22–23 cm long bird with olive-green upperparts and a conspicuous bright yellow tip to the black tail. The head is grey with a yellow supercilium, and the strong bill has a hooked upper mandible. The underparts are bright yellow with a broad black collar between the throat and breast, which continues up the neck sides through the eye to the bill. The legs and feet are blue-grey. The sexes are similar, but juveniles are a dull grey-green below, and lack the black gorget.

There are four subspecies, differing mainly in colour shade and size. Although the species as a whole is not threatened, the isolated dark subspecies restrictus in the Chimanimani Mountains numbers only about 400 birds.
