476 BRITISH BIRDS' NESTS. 



Time. April, May, June, and July, although 

 the last-named month is somewhat late. I found 

 some years ago a member of this species in 

 Hertfordshire sitting on eggs as late as the first 

 week in August. 



Remarks. Migratory, arriving in March and 

 April, and departing in August and September 

 according to some authorities, and October accord- 

 ing to others. Specimens have been seen during 

 the winter in the southern counties of England. 

 Notes : long and shrill. Local and other names : 

 Oven Bird, Jenny Wren (a name also applied to 

 Common Wren), Scotch Wren, Yellow Wren, Hay 

 Bird (a name also applied to the Whitethroat), 

 Huckmuck (also applied to the Long -tailed Tit), 

 Ground Wren, Mealy Mouth. A close sitter. It 

 has been asserted that female Willow Warblers 

 sometimes hover over their nests like humming 

 birds, but, although I have watched a good many 

 individuals of this species during the last thirty 

 years, I have never once seen the bird practise 

 the feat.
