AUTHOR: BEHROUZ BEHROUZI-RAD

Abstract

The study of breeding biology and population of Western Reef Heron Egretta gularis carried out from April to August 2014 on 7 islands in Khore Mosa Creek in Persian Gulf. I estimated the breeding population, mortality, natality and the breeding success of this species in 7 islands of Khore Mosa Creek. The breeding success during the incubation, nestling, post-nestling and overall stages were 56.76 %, 80.95%, 78.82% and 36.21%, respectively. Being eaten the eggs and chicks by Common Buzards Buteo buteo, high temperature and due to unknown reasons were more important causes of their mortality. The average weight of chicks was 21.75�0.71 and 586.14�10 g at hatching and fledging respectively in Khore Mosa Creek Islands. The maximum nests counted in Heidari2 (17 nests) and minimum was counted (1nest) on Tiff2 island.
