July, 30. The Kheta ranger’s station and downstream portion.
Early in the morning we went downstream. We have flown UAV missions at every nest either by Irina’s or mine aircraft. In total there were 5 chicks on the Chelomdja river during this survey. In June, Irina saw 14 chicks and 2 eggs in the Chelomdja nests (all drone-documented). I think this is the fist truly documented decline in the productivity during a single season. At the end of the day we reached the Centralniy ranger’s station.
