P. DeBenedictis 1965 Col. deis melanotus 23 June Barrow Alaska The two birds were clearly 8's as they were the same size and both hooded. No 9's were seen perhaps explaining why this took place, the 8's by now being ready to mate with any entity that looks like another Pectoral Sandpiper. This was seen by Dr. W.J. Breckenridge, who was at my side. 24 June. Two 8's, one of which hooded, and another flew in an arc, least distinguished but silent, on two occasions, and a lone 9 seen in the above area. A fledgling Ploceus feeding near this bird took one peek at the Pectoral's head, causing the Pectoral to fly. Saw a few males but only one displaying along Elson Lagoon in the afternoon. 25 June Only scattered birds were seen along the beach ridge, one 8 flying about with the chest expanded but not calling. In the afternoon 2 flight "hoots" were heard, 8's seen giving a brief chase to a 9 and this 9 was jumped from a low mound in a relatively level area on which a nesting pair was found. About 6 PM a chase involving 2 (almost constantly) and occasionally 3 8's and a 9 was seen, lasting almost a minute. No display but an occasional greeting call was heard. At the onset 2 8's were chasing the 9 who flew over 100 yards to an area where a 3rd flew judiciously. He got up, joined the chase for a few seconds, landed, the original 3 birds moved away, came back, the 3rd again joining the chase, then landing, and after this
