*Liilltlla arborea arborea. The VVood-Lakk. An occa- 

 sional visitor to the island. The records are : one on 16 & 

 17 October 1910, and one on 29 September 1912, both 

 vvitli south-easterly winds 



Otocorys alpestris alpestris. The Shore-Lark. An occa- 

 sional visitor in autumn. One was killed at the lantern on 

 11 October, 1907 (S.E., very liglit) and sent to us, two were 

 seen on 13 October, 1909, and one on 14 & 16 (S.W. & W., 

 fresh to strong) and four on 9 October, 1913 (E. & N.E., 

 moderate). It will be noticed that this species has occurred 

 in both types of weather, it, like the Lapland Bunting, 

 having a circumpolar distribution. Shore-Larks have a 

 sweet wild note, " hi-yi-yi/^ which they utter constantly 

 when flushed ; we often watched them settle half-way up a 

 rock, run to the top, elevate their " horns," stretch their 

 necks, and look around them.

 Pied Wagtail being on the island from 24 December, 1885,
