Identical to grey-backed camaroptera except that the mantle is green (not grey). It might be confused with Karoo eremomela, which frequents much drier habitats, but the eremomela has a much longer tail, yellow-washed flankes and a pale (not dark) eye. It characteristically cocks its tail.
Juvenile is slightly streaked below.
Moist evergreen forests and scrub.
A nasal 'neeehhh' and a loud, snapping 'bidup-bidup-bidup'.
