Pectoral Sandpipers were seen only in 1967, when at least one female nested. Unfor- tunately no specimens were collected. The species was first identified on 19 June when the following description was re- corded by Holroyd: "yellow legs, dark breast, white belly, brown back, light wing bar, white outer tail feathers, black inner tail feathers, bill P/2-2 times head, larger than White-rumped Sandpiper.'' One to three birds were seen on several day

The species was first identified on 19 June when the following description was re- corded by Holroyd: "yellow legs, dark breast, white belly, brown back, light wing bar, white outer tail feathers, black inner tail feathers, bill P/2-2 times head, larger than White-rumped Sandpiper.'' One to three birds were seen on several days until 25 June. On that day Hussell saw one performing a distinctive circling flight display ("gull-shaped wings") in which the breast was held out while the bird uttered a "bubbling" or "gurgling" note. This was apparently the hooting flight display described by Pitelka (1959). On 30 June a Pectoral Sandpiper was flushed from a nest containing four eggs (Figure 2) in a grass tussock at the edge of a small pool. The following day the eggs had gone, presumably taken by a predator, and the species was not seen again. Breeding is clearly exceptional on this part of Devon Island, and this record is well to the north of the previously known range, the most northerly portions of which are south of 75° N on Banks Island and Prince of Wales Island (Godfrey 1966). White-rumped Sandpiper. Erolia juscicoUis. This was the third most abundant shorebird breeding on the Truelove Low- land, only Baird's Sandpipers and Black-bellied Plovers being more numerous. White-rumped Sandpipers were, however, less common in 1969 than in the other three years. They arrived later than Baird's Sandpipers, the earliest dates being 19 June 1967 and 18 June 1968. In 1966 and 1969 they were not recorded until 30 and 26 June, respectively, but earlier arrivals may well have gone unnoticed in those years. On Bylot Island White-rumped Sandpipers arrived on 19 June in 1954 (Drury 196
