The last of these examples, and a Nutcracker (Nucifraga) shot on 

 the 15th of the same month, were the only eastern occurrences during 

 the whole of the autumn migration. This was owing to the violent 

 west winds prevailing, almost without exception, at that time, which 

 invariably, in the most decisive manner, prevent the movements of 

 migration from proceeding within the range of our observation. 



110. Pallas's Willow Warbler [GOLDHAHNCHEN-LAUBVOGEL]. 

 SYLVIA PROREGULUS, Pallas. 1 



Motacilla proregulus. Pallas, Zoog. Boss.-Asiat. i. 499. 



Clans Aeuckens has been a devoted fowler and gunner from his 

 earliest youth. Before he had reached the age when he might be 

 entrusted with powder and shot, his shooting gear consisted prin- 

 cipally of a hunting-bag full of rounded pebbles, which he knew 

 how to employ with the most astonishing dexterity. It was with 

 such a pebble that, at the age of eleven years, he hit the first 

 example of Emberiza rustica ever killed on the island. 



In later years, at times when the Guillemots were flying along 

 the edge of the cliff at a tearing speed, I have seen him hit five or 



1 Phylloscopus proregulus (Pallas).
