JAM Verbeek 1966 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.
