Variation of plumage in the direction of leucotism 

 is rare in the Sylviadce, but in 1879 two Willow 

 Warblers were shot near Cummersdale, presumably

 in which the ground colour is white, blotched with

 Warwick Bridge, and of hearing its familiar song. 

 The entire under parts were of a very delicate cream

The Reed Warbler is a rare summer visitant,
