Maclee 1969 Calidris >June DWP though he saw 1 on Britton's Area this aft. 11 June Saw 3 birds feeding actively on Beech Ridge, so. of F.a.d.. Later saw 2 birds together near the same area. One of these was a ♂. Twice the birds were flushed - once by me, once by a caterpillar tractor. Both times the ♂ followed the other (presumed ♀) and gave ground display upon landing - tail cocked, forward posture, wings partially extended - buzzing note. No visible response from other bird, and displaer resumed feeding.
