Black Crowned Crane is a resident species in Ethiopia. However, the available informationrnon the breeding, feeding ecology and its status is in adequate. This study was carried outrnin Lake Tana area, from 2014-2016. The study aims to investigate the breeding and feedingrnecology, distribution, abundance and habitat change of cranes. Different statistical toolsrnwere used to evaluate the different parameters. ANOVA and Shannon diversity index, arnfixed GLM procedure and MANOVA were applied. A total of 74 and 56 transects in 2015rnand 2016 was carried out to estimate the abundance and density of cranes. MultiplernCovariate Distance sampling model was employed for distance analysis. Wetland habitatrnshrinkage was evaluated from the land use land cover change from 1986 to 2016. Thernresult showed that all crane nests were located only in wetlands where water depth rangedrn135-220 cm. The active nesting time was September to October. The inter-distance betweenrnnests did not vary from site to site. Cranes utilized nest materials collected from the nestingrnplace. The mean vegetation height at which the nest constructed was variable. The nestrnmorphology parameters were not different statistically. The nesting density was 6-7 /100rnha. The average clutch size of Black Crowned Crane was two (n=92). The mean length ofrneggs was 76.94Â±.22 mm, and width measured 54.05Â±.07 mm. The mean weight of eggsrn(n=92) were 111.99Â±.65g. There was a positive correlation between egg length and width,rnand were statistically significant. Hatchability was 91.3%, but the pre-fledged percentagernwas about 50%. Oryza longistaminata and Leersia hexandra were the dominantrnmacrophytes. The distribution and biomass of macro-invertebrates were significantlyrndifferent across study sites (P
