It has been quite a while since our last updates and we are delighted to see that both KS and KU have reached their breeding sites!
KS reached the west of Momskiy Mountains in the last week of May. After spending two days there to replenish, it flew 157km east across the 2000m mountains to reach its nesting location.
Within a few days of arriving, KS has chosen its nesting area. The movement of KS in its first week of arrival was quite extensive, covering up to an area of 500km2. Moving on to the second week, movement significantly shrunk to less than 100km2. Movement further limited to a 5km x 5km area in the third week indicating that KS is highly likely to be nesting.

Also within a week of arriving, a significant change in area of movement was observed. In the first week, KU moved in a wider area of up to 520km2. Afterwards, it settled down in the second week within a 13km x 10km area.

On top of KS and KU which successfully made their journey to the breeding ground, we still regularly receive signals from both LA (at Eighty Mile Beach) and JX (at Palawan, the Philippines).
