As regards those species that are also resident on the 
island, there^was, we think, some movement among Hedge- 
sparrows, and a considerable immigration appeared to take 
place on September 28th and 29th, but all the specimens 
procured were of British race. 
On September 24th, a Redbreast, which, from the situa- 
tion and the behaviour of the bird itself, we believe to have 
been a migrant, was flushed among the rocks by the sea- 
shore. 
The Skylark and the Green Plover are both common 
breeding species, but the native birds had left by the second 
week of September, and the northern birds did not appear 
until the end of the month, when there was considerable 
immigration. 
Goldcrests were constantly observed during the latter 
part of September, although never in large numbers. 
Swallows were only observed once — on September 19th — 
when three birds were seen. Pied Wagtails were constantly 
seen throughout September, but the Grey Wagtail onh^ 
appeared on September 26th, when two birds were seen. 
Missel-thrushes, in a flock of seven; were observed crossing 
the island in a south-westerly direction, on September 25th. 
•a. day when considerable migratory movement was observed 
among several species, 
Rathlin does not offer much inducement to the marine - 
feeding waders. Ringed Plover, Turnstones, and Red- 
shanks were common throughout our stay, but the Dunlin 
was only recorded on September 19th, and again on the 
28th, five birds being seen at one time and two at another. 
A male Grey Plover was seen on September 29th and 30th. 
Terns were only observed once — on September i6th — and a 
single Shoveller was seen on fresh water on September 20th, 
Regarding breeding species, it is perhaps worth recording 
the islanders' account of the extraordinary diminution of 
sea -fowl during the previous two summers. At one time 
the birds could not move on the ledges without stepping 
on their eggs," but last year few were seen. This is attributed 
to the building operations connected with the new lighthouse 
that is being constructed close to the once famous rock
