A name now in general use for the Water-OUSEL, but apparently invented
in 1804 by the author of Bewick's British Birds (edition 1,
ii. Page 17) because "it may be seen perched on the top of a stone in the

also in Australia to the Restless Flycatcher (Myiagra inquieta,

This often persists throughout life in the NIDIFUGAE, and occasionally,
as in the RATITAE, retains a small quantity of degenerated yolk, while
in the NIDICOLAE or Altrices
it is generally absorbed before maturity.
The name given, according to Nuttall (Manual of the ornithology of the
United States and Canad, ii. page 102), indiscriminately by the English
in eastern North America to some species of Curlew
and GODWIT. In particular, Trumbull stated in his Names and Portraits
of Birds, page 203, that the name is rightly applied to a small
species called the Northern Curlew Numenius borealis, also known
as the Eskimo Curlew.
The Australian name for Eurystomus orientalis, from the silvery
white spot in the middle of the wing, which is distictly shown in flight
(Gould, Handbook of Birds of Australia i. page 120). The genus Eurystomus,
is one of the Coraciidae (ROLLER) family, contains four species
(within which numerous subspecies exist), belonging to the Indian or Ethiopian
