Summary
Tomlinson, D. N. S. 1979. Interspecific relations in a mixed heronry. Ostrich 50:193-198.
Fortnightly censuses were conducted at a heronry in Lake Kyle, Rhodesia, from January toMay1974, and while certain species (Reed Cormorant Phalacrocorax africanus, Grey Heron Ardea cinerea and Black headed Heron Ardea melanocephala) continued to arrive in small parties throughout the breeding season, others (Great White Egret Egretta aha, Cattle Egret Bubulcus ibis and Night Heron Nycticorax nycticorax) exhibited a high degree of breeding synchrony. P. africanus showed a significant nesting association with A. cinerea and A. melanocephala, while N. nycticorax was associated with C. albus. B. ibis did not show any significant nesting association with the other species.
