THE FLANNAN ISLES 271 



May 1904, when it occurred at the lantern in numbers, 

 along with Wheatears. 



Its autumn visits are frequent, and are recorded from 

 20th August to 8th October. 



Tree-Pipit, Anthus trivialis. — A single visit only is 

 known. One killed at the lantern on the night of 25th 

 September 1908 was sent to me. This species had not 

 previously been known to occur in any of the islands of 

 the Outer Hebrides. 



Rock- Pipit, Anthus obscurus. — Resident all the year 

 round, and very numerous. Many perish in winter, 

 probably from want of food, but the lightkeepers say 

 from exposure. 



There are entries in the records of their presence in 

 great numbers on 21st April 1901, and on 17th Septem- 

 ber 1902, and these may refer to passage movements on 

 the part of this .species. 



Red-backed Shrike, Lanius collurio. — A bird of the 

 year was killed at the lantern on 14th September 1909, 

 and was forwarded for identification. This species is 

 not known to have occurred previously in the Outer 

 Hebrides. 



GoLDCREST, Regulus regulus. — Several occurred in 

 a rush of migrants on 30th October 1908. This is the 

 only known visit of this species to the island, and bears 

 out the general pronouncement on the scarcity of the 

 Goldcrest as a migrant in the Outer Hebrides. 



Common Whitethroat, Sylvia sylvia. — One captured 

 in May 1907 was sent for identification. There are 

 records for 3rd June and 23rd September 1902, but 

 these are of a somewhat doubtful nature. 



Lesser Whitethroat, Sylvia curruca. — One was 

 obtained on 23rd September 1904, and sent to me.
