 spray, sometimes dancing and jerking in the air,

 Whitethroat, being merely a kind of convulsive 

 laugh or call, occupying about half a bar of common 

 time.

 garden at Willesden Green, at the height of nearly

 throat's usual habit about here to place its nest 

 higher than most of its congeners, excepting some-

 of the earliest to arrive of our summer Warblers, 

 and usually has its nest completed early in May : 

 last year we found an egg on the 28th April. The
