Breeding conditions:
|
| BIrd started breeding two weeks earlier than in 2004, and all pairs of Siberian Cranes and Sandhill Cranes in the vicinity were incubating in late May. Snow has mostly melted by the time of waterfowl migration and it was not intensive in the area. We recorded 25 flocks from 10 to 100 Black Brants passing from 0:53 to 11:55 on 31 May at an altitude 100-150 m. Numbers of Baikla Teal increased dramatically compared with previous years, and they were seen everywhere. A nest of Baikal Teals was found on 12 June with a clutch of 10 eggs. The season was generally favourable for birds.
