Striata or maritima, the Curlew-Sandpiper, T.
Silurian rocks, with Old Red Sandstone over them, come out at the west end of the Curlew range at Ballaghaderreen.
The ibis is somewhat larger than a curlew, Numenius arquata, which bird it resembles, with a much stouter bill and stouter legs.
On the plains a few waders breed, as the avocet, western willet and longbilled curlew; but most are birds of passage.
There are numerous species in these sheltered channels, inlets and sounds of geese, ducks, swans, cormorants, ibises, bitterns, red-beaks, curlew, snipe, plover and moorhens.
