This
is the 6th week since KS arrived at its breeding area and some movement away
from its nesting area has been observed in the past few weeks.
In
the previous “Updates” we’ve seen KS settled down at its nesting location since
the 2nd week. Whimbrel incubation period takes about 4 weeks with both parents
sharing the duty.

Movement of KS around nesting location:
Week 2: 6-Jun to 12-Jun
|
Week 3: 13-Jun to
19-Jun
|
Starting from
the 4th week, KS began to move between its nesting location and another
location about 12km south-west. On the 5th week, it even left the nesting
location for a week and forage in an area with small lakes about 40km
north-east, which is an obvious indication that its young have hatched.
Week 4: 20-Jun to 26-Jun
|
Week 5:
27-Jun to 3-Jul
|
Week 6: 4-Jul to 9-Jul
|
In the 6th
week, KS has come back to the nesting area with occasional movement to the
south-west area where it visited in the 4th week. It will take another month
for KS’s young to fledge and it is expected that KS and its partner will
stay around to take care of their offspring.
On
the other hand, based on KU’s movement, it looks like that it is still
incubating its eggs. Let’s hope we can observe similar movement of KU away from
the nesting location in the coming weeks.

Movement of KU around nesting location:
Week 3: 21-Jun to 27-Jun

Week 4: 28-Jun to 4-Jul

Meanwhile,
we still receive regular signals from both LA (at Eighty Mile Beach) and JX (at
Palawan, the Philippines).
