Abstract
Breeding season is one of the natural events occurring annually with objectives on maintaning the population and producing the offsprings. Waterbirds require various conditions to enter the breeding season including the sites and time of breeding. Selection of breeding sites will determine the success of breeding waterbirds. Breeding season study was conducted using direct observation methods from August to June during 2016-2018. This study aims to determine the breeding cycle and life cycle of waterbirds in Tanjung Rejo district, Deli Serdang regency, North Sumatra, Indonesia. Based on the research results, the breeding season of waterbirds in Tanjung Rejo occurs twice in a year. This breeding season of water birds occurs simultaneously in September until December, and February-June for four identified species namely: Egretta alba, E garzetta, Bubulcus ibis and Phalacocorax sulcirostris. As for Ardea cinerea and Nycticorax nycticorax, breeding season occurs in August-November and January-May. The clutch size of each bird ranges from 2 to 4 eggs. The spawning interval for each species is between 1 and 4 days, while the spawning sequence takes place from 1 to 4 days. Incubation period ranges from 25 to 30 days. The success of waterbird breeding is determined by both climate and food factors.
