THE AQUATIC WARBLER. loi 



migration of birds, having now been published, 

 will kee'p his name green wherever ornithology 

 is studied. 



The name of the Aquatic Warbler has tran- 

 ferred me, in thought, back to the rocky isolation 

 of Heligoland, with its collection of bird-treasures, 

 its hermit-ornithologist, its potato-covered height ; 

 for it was in the latter unlikely locality that I shot 

 my first specimen of the " Aquatic " Warbler. It 

 was easy to be up with the lark in that breezy 

 air, and we usually commenced the day with a 

 walk through the potato-fields on the summit of 

 the island, when a varied bag was the result. 

 On the morning in question, I think my captures 

 were something like the following : a Wood-lark, 

 a Jack Snipe, a Brambling, a Snow-Bunting, and 

 lastly, an Aquatic Warbler ; the last-named being 

 the only one seen by me on our expedition, as it 

 is not a common migrant to Heligoland. It is 

 not even known to visit Denmark or Southern 

 Scandinavia, though it is pretty generally dis- 

 tributed over Central and Southern Europe, and 

 appears to winter in Northern Africa. It has 

 been detected three times in Great Britain. 



As might be expected, the Aquatic Warbler
