oo2 Recently published Ornithological Works. 



This last autumn Mr. Clarke deserted Fair Isle for 

 Auskerry, a small uninhabited island of 260 acres, and one 

 of the most easterly of the Orkney group. Here on 

 October 3 last, among a number of southward migrants, he 

 secured an example of Phylloscopus fuscatus, another Asiatic 

 straggler breeding in eastern Siberia and wintering in India. 



Mr. Eagle-Clarke also describes as a new subspecies in 

 this volume (p. 53) the form of the Song-Thrush inhabiting 

 the Outer Hebrides under the name Turdus musicus hebri- 

 densis. It is quite easy to distinguish it from the Song- 

 Thrush of our islands, and owing to the absence of trees 

 it breeds among the rocks. 



Miss Baxter and Miss Uintoul, whom we may perhaps 

 describe as pupils of Mr. Clarke, are also addicted to 

 visiting small islands to observe migration. They spent the 

 months of May and September 1912, as well as September 

 1913, on the Isle of May, at the mouth of the Firth of Eorth, 

 making observations on migration and looking out for rare 

 stragglers. They were fortunate enough to discover Hypo- 

 lais polyglotta and Sawicola indica, both of which have never 

 been met with in Scotland before. 



A systematic and full report is given by Mr. A. L. 

 Thomson on his Aberdeen bird-marking scheme. The most 

 interesting case we have noticed is of a British Song-Thrush 

 which was ringed near Aberdeen in June, and was killed 

 near Lisbon in November. We hardly yet know of any 

 definite records of our British race outside our islands. 



Mr. Peter Anderson contributes an interesting list of the 

 birds of Tiree, an island lying off the coast to the west of 

 Mull. It is remarkable how many birds are noted as winter- 

 visitors only ; the Song-Thrush, Blackbird, Stone Chat, 

 Redbreast, Wren, and Goldfinch are all included in that 

 category, and we may conclude that the winters there are 

 comparatively mild although it lies so far north.
