Calidris canutus (3)
When I was around the young the female called the Knot. Knot distress call, and in response to the discomfort peep of the young she made chucking noises, very soft and somewhat reminiscent of a chicken. She brooded the young by holding one under each wing and two under the chest. The young moved head first, so that their dorsal ends stuck out.
There was only one adult with the chick and no other adult to be seen anywhere. When I walked away I heard the ooo see call, apparently given by the bird in attendance of the chick. If this is true, the male was in attendance of the young, since this is a call given by the male (see 15 June).
14 July
Steve and I went to the Drum Area and found the Knot + 3 chicks about 50 S. of the Santerling nest. We took some more pictures. I again heard the bird making the male type call.
Prepared the skin of the Downy young 6-day (NAMV 147) and found a yellow yolky material inside the bird, indicating that it had only recently hatched.
15 July.
Found the Knot (only one adult) with his three young on the S. side of Honey Bucket, roughly 800-900 m from where I found them 13 July. Characterized the spot:
499 3? lp w 36A 1/2 o.
As I walked away from the chicks the adult walked in front of me, calling knot-knot, occasionally flying to stay ahead of me. When I was about 25 m away from the young he began the typical Calidrid crunching walk, accompanied by squeaks.
I returned to the chicks, to see whether she would repeat this
