THE SINGING OF BIRDS ON MIGRATION. 



To the Editors of British Birds. 

 SiRS^ — I can quite bear out Mr. Headley's experience that some 

 birds sing while on migration, and surely the autumn-song of the 

 Willow-Warbler and Chiffchaff heard in places where they are 

 imdoubtedly halting on migration, must be familiar to most field- 

 ornithologists. The Golden Oriole I have heard singing in Egypt 

 durmg a halt on migration in spring. The Rufous Warbler of course 

 is a spring -visitor to the Nile Delta, breeding abiuidantly there, and 

 not, so far as I am aware, wintering there.
