This study carried out from April to Jun 2010. Breeding behaviour of Collared Dove started at 8 April with observation of nest building and finished at 9 June with flight of last fledgling. During the study period 19 nests with 38 eggs (mean of 2.0 eggs per nest) surveyed. In total, 60.5% of the eggs hatched and 60.9% of hatchlings reached near-fledgling stage, giving an overall breeding success of 36.8%. Mean nest productivity was 0.7 ± 1.0 fledglings per breeding pair and 1.2 ± 1.0 fledglings per successful pair. Breeding failure had a significant difference in the egg stage, chicks before18 days and chicks older than 18 days (p < 0.05). Nest parameters had not a significant effect on the breeding success. 46.7% nests were ravaged by birds, 26.7% – by mammals, 13.3% – by reptiles and 13.3% clutches and broods were lost owing to bad weather.

Key words: breeding period, nest, egg, breeding success, predation.
