20 STUDIES IN BIRD-MIGRATION 



ears arrived and continued to fly around while the sky 

 remained overcast. 



On 25th September, between i and 4 a.m., during 

 light rain, many Wheatears, Redstarts, Pied Flycatchers, 

 Whitethroats, Willow- Warblers, Tree-Pipits, Skylarks, 

 and a Richard's Pipit (examples of all of which were 

 killed at the lantern), doubtless with other species, 

 were flying round the vessel, and great numbers struck 

 the glass and were lost in the sea. The presence of 

 Richard's Pipit, a Central European summer bird, 

 suggests that this movement was, at least in part, from 

 east to west. 



On 29th September, between 2 and 5 a.m., Black- 

 birds (those killed being immature males). Redstarts, 

 Pied Flycatchers, Wheatears, Goldcrests, and Skylarks 

 were present in great numbers, and hundreds struck the 

 lantern and fell overboard. 



On 3rd October, from 1.30 to 4 a.m., Goldcrests, 

 Mistle-Thrushes, Song-Thrushes, Blackbirds, Chiff- 

 chaffs, Meadow-Pipits, Wheatears, and others were 

 flying round. The rays of light were not very brilliant, 

 however, and comparatively few perished at the lantern. 



The fortnight that followed was devoid of night 

 movements. There were days on which much east-to- 

 west migration was witnessed, but the nights were bird- 

 less, so far as observation was concerned, for the weather 

 conditions were not such as to render the lantern 

 attractive to passing migrants. 



From 6.30 P.M. on the night of 17th October to 5 a.m. 

 on the 1 8th, Starlings, Larks, Chaffinches, Jackdaws 

 (a few), Rooks (a few), Mistle-Thrushes, Song-Thrushes, 

 Wagtails, Goldcrests, Meadow-Pipits, and probably many 

 other species were careering around the ship, and
