Animalia > Chordata > Aves > Passeriformes > Chaetopidae > Chaetops > Chaetops frenatusChaetops frenatus (Cape Rockjumper)The Cape rockjumper or rufous rockjumper (Chaetops frenatus) is a medium-sized insectivorous passerine bird endemic to the mountain fynbos of southernmost South Africa. This is a ground-nesting species which forages on rocky slopes and scree. It frequently perches on rocks. Breeding groups occupy 4–11 ha territories, and typically consist of a breeding pair and one or two additional individuals, usually offspring of the adult pair from the preceding breeding season. These helpers participate in territorial defence and alarm calling, and in the feeding of nestlings and fledglings of the breeding pair. Females also help with nest building and incubation. |
