Решение проблемы определения статуса гнёзд белобрюхого орлана – важная задача для планирования охраны этого вида

Abstract

In the present study, I monitored nests of the White-bellied Sea Eagle Hialiaeetus leucogaster from September 2012 to September 2013 every two weeks. Maximum 40 adults and 4 juveniles were counted during this study. The 75 nests present here are categorized in five groups: Not occupied (63 %), occupied with low potentiality (12 %), with medium potentiality (20 %), reserved (4 %), and active nest (1 %). Successful breeding was observed only in one nest that raised the problem of nest occupancy and this problem is discussed in this article.
