MacLes 1967 Pluvialis dominica 8 June Birds were well scattered, but frequent, generally. Mostly paired - pairs W. gasoline, S end of P's plot, N end of plot... Displaying over W. gasoline Pair - no reaction from the others. 9 June Watched a pair on Beach Ridge WE of Micro Meter - stood quietly with some feeding, but no reproductive activity. 12 June Pairs are still spread out; Display not infrequent. Saw a bird on Village Ridge chase away a ♀ Pectoral - chased it about 40 feet 13 June Birds are approaching 'normal' density - occupying new territory as it is exposed. Birds do not appear to be incubating yet. 18 June Area East of Footprint Lake - birds are still quite active and do not appear to be incubating. Much display, and careful watch of territorial boundaries. Any trespass → instant chase, followed by Display. Saw 1 'ass-up' which led to copulation. Unsettled birds were causing disruption - could they be just arriving?! On the way in collected one bird that appears to be the odd bird interacting with a pair. Turned out to be a ♂ W/ 15mm
