There was significant difference between mortality in various stages (Pandlt;0.05). According to the Mann Whitney U test results, there was significant difference between the success in touched and untouched nests (Pandlt;0.05). Two Most important factors that decrease the success rate were predatory and climatic turmoil respectively that cause to eggs destroying and this occurrence happened in the start of reproductive season.
