Calidris canutus (4)
Behavior sequence. Again, when I walked away from the chicks,
the adult walked in front of me calling Knot-knot, and this walking
went over its a crouched walk + squeeking when I was +25 m
from the groy. He kept it up for some 150 m and then flew
back to the chicks.
The breast feathers of the adult look very motled indicating
that he is molting.
16 July
Found the Knot back between the shore of Honey Bucket and
Stephen's hive plot, about 100 m from where they were yesterday.
Characterized area.
502 37 f w %A 3/2
18 July.
The Knots had moved to the mouth of Voth Slough, about
500 m from where I saw the last. I only saw one chick
with the adult
19 July
Heard the Knot in the area where Steve and I saw them on
14 July. This means they moved from the Voth Slough area
to near the Sandling nest in one day, roughly 1000 m.
This seems like a long distance. Steve saw the adult
but did not search for the chick (s'). He thought the adult
behaved as if he had chicks.
20 July.
Walked the Polygon along the East S. shore of Honey
Bucket and did not hear the Knot. If the bird had only
one chick left on 18 July, it might be that he lost that
chick and that when Steve saw the adult yesterday, the
bird was without chick (s'), hence the long distance.
