312 STUDIES IN BIRD-MIGRATION 



observed between 30th September and 14th October. I 

 observed it in the morning from 6 a.m. to noon, and at 

 night captured old and young birds at the lantern during 

 the main movements southwards. 



MoTACiLLA EOARULA, Grey Wagtail. — There are no 

 spring observations. In the autumn it has occurred from 

 17th September to 6th November. I captured one at the 

 lantern on the night of 14th October, and observed others 

 passing south on several occasions during the forenoon. 



MoTAciLLA RAYi, Yclloiv Wagtail. — There are a 

 few records only, all for the autumn passage, and at 

 dates ranging from 23rd to 30th September. On the 

 former date I captured an adult and a young bird at 

 the lantern and saw many others flying around from 

 3 A.M. to 5 A.M. 



Anthus tratensis, Meadoiv - Pipit. — Very abun- 

 dant during the spring and autumn passages. Noted in 

 spring from 25th February to i8th April, during the 

 night and earliest hours of the morning. The autumn 

 emigratory movements date from 4th August. Great 

 numbers pass southwards continually during September 

 and October, from 6 a.m. until noon ; and many also 

 visit the lantern during the night "rushes" across the 

 Channel. It has been observed as late as the last week 

 of November, but may then have been driven south by 

 an outbreak of cold weather on the mainland. 



Antiius trivialis, Tree-Pipit. — Examples, killed at 

 the lantern on 29th August 1902 and 21st September 

 1887, were forwarded to me for identification. 



Antiius obscurus, Rock-Pipit. — Has been recorded 

 as occurring during the great autumn movements, 

 but I have never received specimens or wings for 

 identification.
