The light -keepers told him that four or five years 

 previously they saw large numbers of small birds taken by 

 Sparrow- Hawks^ and that the island was strewed with the 

 feathers of their victims. 



On the night of the 16th of October, 1910, there was 

 apparently a great influx of migrants. Numbers of birds 

 passed the light and many struck about midnight; there was 

 very little wind, the sky overcast, and rain falling. Among 

 those taken at the light Wang noted one Sparrow-Hawk, 

 some Grey Wagtails, one Butastur indicus, one Pandion 

 haliaetus, one Lanius tigrinus, one Anthus gustavi, one 

 Acrocephalus bistrigiceps, one Locustella lanceolata, five 

 L. ochotensis, and two Hirundo gutturalis. 



On the 16th, 17th, and 18th of November in the same 

 year a great number of small birds died of cold on the 

 island. The principal sufi'erers apparently were Turdus 

 obscurus, Alauda arvensis cinerea, and Emberiza rustica.
