WILLOW-TITMOUSE [No. 98, British Willow-Titmouse ; 
No. 99, Northern Willow-Titmouse]. A close ally of the 
MARSH-TITMOUSE, first identified as a British bird by 
Mr. Hellmayr in 1900, although the Continental form 
(which has been identified once in our own islands) was 
distinguished as long ago as 1843 by De Selys-Longchamps. 
In Scotland, the British Willow-Titmouse appears quite 
to replace the Marsh-Titmouse. 
WILLOW-WARBLER [No. 122, WILLOW-WARBLER ; 
No. 123, Northern Willow-Warbler]. Willow-Warbler ap- 
pears in Yarrell (1843). It occurs in Pennant (1766) as 
Willow Wren, but by most authors from Edwards to Fleming 
(1842) it is termed Yellow Wren. Macgillivray calls it the 
“ Willow Woodwren.” It is the “ Regulus non cristatus” 
of Willughby. The Siberian form has been identified in 
our islands on migration. 
Witty : The COMMON GUILLEMOT. (Norfolk.) 
Witty Fisher: The COMMON TERN (Forfar) ; the DIPPER 
(Teesdale). 
Witty Gow: The HERRING-GULL. (Scotland.)

found in Don’s “ Fauna of Forfarshire.”’ 
Willy-wickeT: The COMMON SANDPIPER. (North 
England.) From its note. 
WILSON’S PETREL [No. 322]. The name is found in Jenyns 
and in Yarrell (Ist ed.) and subsequent authors. Itisnamed 
in honour of Wilson the American ornithologist, who first 
figured it, but without being aware of its distinctness from 
the STORM-PETREL.
