MR. II. M. W.A.LLIS ON NATURAL HISTORY OF ARRAN SIORE. 463 
RiuUly Sheldrakes {Tadorna casarca) drew my attention to their 
downy brood, scrambling into the water, about fifty yards oft. 
After proceeding a short distance, I came upon a colony of 
Black-winged Stilts’ nests. They wei'e dotted about the mud 
some few feet from the water’s edge, and were composed of reeds, 
and Avero rafsed some three or four inches above the mud, like 
diminutive Flamingoes’ nests. It would be interesting to know 
Avhethor this elevation represents the utmost rise in the level of 
the lake which was likely to occur. The full complement of eggs 
was four. The old birds flew round with quivering wings, 
uttering a shrill poe-pee-pee. 
Dr. Cullen, writing from the .same locality, described the nests 
as made in hollows in the mud. There is, I think, no doubt that 
ho described the nest of the Avocet, which also affects the borders 
of the same lake, and, no doubt, breeds tliere, although I did not 
come across a nest ; yet the two species were Hying about, making 
an awful row together.
