allowing one to approach closely, not even suspending its occu- 

 pation of searching for food. Should a gun be discharged as 

 the littlecompany draws itself together, the survivors fly a short 

 distance in a compact flock, uttering a low, soft iiveet^ exhibit- 

 ing the upper- and then under-side of the body as they wheel 

 and turn swiftly, and then frequently alight near the very spot 

 where their companions were slaughtered. When on the wing 

 it is recognisable by its white upper tail-coverts, which are very 

 conspicuous. In Labrador it is very abundant, frequenting 

 the rocky shores covered wiih sea-weed or green and slippery 

 from the flying spray. It also resorts to muddy flats and shal- 

 low pools, into which it wades up to the breast in search of 

 marine insects and various animalculce, on which it feeds. It 

 is rather a common bird at certain seasons on the shores of 

 Lake Michigan, having been taken in Illinois, and also in 

 Michigan. In the far north it is a straggler at Point Barrow in 

 Alaska, and also breeds on the Mackenzie river. MacFarlane 

 found the nest on the shore of the Arctic Sea, and on the Bar- 

 ren Ground. This was merely a depression in the ground 

 lined with a few decayed leaves, and contained three or four 

 eggs, rufous-drab in colour, blotched with dark brown or black, 

 confluent at the larger end, and measuring 0-35 inch long by 

 0-95 broad."
