REPORT ON SCOTTISH ORNITHOLOGY IN 1916 159 



191 3 was recovered at the mouth of Tweed in April 

 1916 (3. x. 63), while of two Gannets ringed on the 

 Bass Rock, one in July I9i3,the other in September 1914, 

 the former was recovered at Nieuport Bains, Belgium, 

 in January 1916, and the latter off St Abbs in July 1916 

 (3. ix. 269, and 3 x. 222). A Mallard marked at Stranraer 

 in February 191 5 was recovered at Corsewall Point in 

 January 1916 (3. ix. 269), and a Redshank ringed at 

 Balachraggan, Ross-shire, in June 1914 was recovered at the 

 Cromarty Firth in September 1916 (3. x. 222). Perhaps the 

 most interesting record under this heading for the year, 

 is of a Sandwich Tern, ringed at the Fame Islands in July 



1 914 and recovered at Tarbatness, East Ross, in August 

 19 16; the bird did not appear to have bred (3. x. 151). 

 There are sundry records of Black-headed Gulls, some 

 ringed in England and recovered in Scotland, others ringed 

 in Scotland and recovered in England. Thus, two birds 

 ringed at Ravenglass, Cumberland, the one in June 191 2, the 

 other in May 191 3, were recovered, one in Kirkcudbrightshire 

 in January 1916, the other at Glasgow in August 1916 

 (3. ix. 271, and 3. x. 224). Another of this species ringed at 

 Castle Loch, Wigtownshire, in June 1916, was recovered in 

 Northumberland in September (3. x. 223), and yet another 

 ringed at Cleuchhead, Dumfriesshire, in July 191 2, was 

 recovered at Penpont in the same county, in June 1916 

 (3. x. 223). There are two records of Blackbirds retaken at 

 the place of ringing after a lapse of nearly three years ; a 

 Swallow, ringed at Broughton, Peeblesshire, in July 191 2, 

 was recovered at the same place in May 1916 (3. x. 62). 

 We have referred only to the Scottish records of ringed 

 birds ; the reader should consult the papers quoted from for 

 other interesting returns. 



Plumage. 



On 5th April a cinnamon variety of the Rook was 

 seen near Aberdeen, and a bird of this species is reported 

 from Bruntsfield Links, Edinburgh, with white feathers in its 

 wings, the right wing being much whiter than the left. This 

 is the third winter this bird has been seen there, it was first
