Abstract

Rock martins () are regular summer-breeding visitors to the Braamfontein campus of the University of the Witwatersrand (Wits). The diversity of architectural styles of buildings on the campus offers a range of suitable sites for the nesting needs of birds like the rock martins. The nest is constructed of sand/clay pellets, used as a form of adobe, stuck together to form a 'half-cup' with sides adhering to a vertical wall or rock face. A number of the building façades provide the overhang structure necessary to protect against rain and nest predators.
