SAVrS WARBLER 47 



and June. We are informed by Professor Newton 

 and others that the nest of Savi's Warbler was 

 well known to the Fen men, although they were 

 unacquainted with the parent birds. The nest is 

 carefully concealed amongst the aquatic vegetation 

 from a few inches to a few feet from the ground, 

 and is a well-made, deep, cup-shaped structure, 

 composed almost entirely of the flat, ribbon-like 

 leaves of Glyceria. The eggs — from four to six in 

 number — vary from white to pale buff in ground 

 colour, sprinkled and freckled with light brown 

 and violet grey underlying markings. Both birds 

 are said to assist in incubation, and but one brood 

 appears to be reared in the season. The food of 

 this Warbler consists principally of insects and 

 their larvae. 



Savi's Warbler is a sombrely arrayed little bird, 

 having the general colour of the upper parts uni- 

 form russet brown, darker on the quills. The 

 under parts are pale huffish brown, becoming nearly 

 white on the throat and the centre of the belly, 

 and pale chestnut on the under tail coverts. The 

 female closely resembles the male in colour. The 

 total length of the bird is about five and a half 

 inches.
