Abstract

Cattle egret Bubulcus ibis, feeds on insect pests in many agro-ecosystems. Thus, there is an urgent need to study the breeding chronology of cattle egret, in order to develop suitable protection programs for this beneficial bird to perform its role as abiological control agent in Egyptian agro-ecosystems. The study was conducted at Sharkia Governorate, Egypt, from December 2018 to December 2020; in different habitats (irrigation canals, drainage canals, garbage collection areas and Abbasa ponds). The mean clutch size ranged from 2-5 eggs/nest with an incubation period ranging between 21-25 days. The mean percentage of hatching success was 90.21%, while the total number of mortality eggs was 47 and the total egg hatching was 433. Also the total number of nests located nearby tree trunks were 73, while nests located in the core of the tree were 47 nests, and nests located at the peripherals were 15 nests.

A garça-vaqueira (Bubulcus ibis) alimenta-se de insetos-praga em muitos agroecossistemas. Assim, há uma necessidade urgente de estudar a cronologia reprodutiva da garça bovina, a fim de desenvolver programas de proteção adequados para que esta ave benéfica desempenhe seu papel como agente de controle biológico nos agroecossistemas egípcios. O estudo foi conduzido na província de Sharkia, no Egito, de dezembro de 2018 a dezembro de 2020; em diferentes habitats (canais de irrigação, canais de drenagem, áreas de coleta de lixo e lagoas Abbasa). O tamanho médio da ninhada variou de 2-5 ovos/ninho com um período de incubação variando entre 21-25 dias. A porcentagem média de sucesso de eclosão foi de 90,21%, enquanto o número total de ovos de mortalidade foi de 47 e o total de ovos eclodidos foi de 433. O número total de ninhos localizados próximos aos troncos das árvores foi de 73, enquanto os ninhos localizados no núcleo da árvore foram 47 ninhos, e 15 ninhos localizados nas periferias.
