 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 Wood\ATen." It is the " Regulus non cristatus " 

 of Willughby. The Siberian form has been identified in 

 our islands on migration. 

 Willy : The COMMON GUILLEMOT. (Norfolk.) 

 Willy Fisher : The COMMON TERN (Forfar) ; the DIPPER 



(Teesdale). 

 Willy Gow : The HERRING-GULL. (Scotland.) 

 Willy Hawkie : The LITTLE GREBE. (Clough, Antrim.)

 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 (1st ed.) and subsequent authors. It is named 

 in honour of Wilson the American ornithologist, who first 

 figured it, but without being aware of its distinctness from 

 the STORM-PETREL.
