A M Verbeek. 1966 Squaterola squaterola (I) 1 July. One single brid feeding in Central Marsh at 12:00 3 July One single brid feeding in Central Marsh at 15:00 17 July Two brids in fall plumage W. of South Meadow Lake 23 July At Meade River I noticed several pairs on the polygon ridged. It looked like they had not molted as much as the Golden Plovers, but all of the pairs I saw behaved as if they had chicks nearby. 26 July. The brids around here seem to be very much concerned with chicks yet. I have not seen any concentrations of adults. 28 July. The more familiar I become with the various displays of the shorebirds around Barrow and Meade River, the more convinced I become that if a bird is superficially similar to another species - Baird Sandpiper - White- rumped Sandpiper (similar except for the white rump) and Golden Plover - Black-bellied Plover (most striking difference is the size and the white upper tail in the latter) then those features which are dissimilar are being used in various displays. In its distraction display around the nest, the Golden Plover deflects the tail and beats the spread wings on the ground (see also description of display in entry of 30 June). In the Black-bellied Plover the wings are spread too and beat on the ground but the tail, instead of being deflected is cocked and spread, taking full advantage of the white upper surface. This makes the bird much more conspicuous. 31 July Some one brid today. They seem to have left the country
