E. pusilla , E. hortulana, Turtur communis , Totanus ochropus , 
and other species of less importance are recorded on 
Mr. W. E. Clarke's authority from Fair Isle, while it may 
be noted that Corvus cor one has also occurred there; an 
early nest of Phalacrocorax graculus is noticed from Orkney 
(Feb. 24th) ; two pairs of Somateria mollissima remained 
from April to August on the Solway Firth; a pair of 
CEdicnemus scolopax are reported from Lerwick on May 20th ; 
Fringilla montifringilla and Scolopax rusticula (cf. Annals, 
1907, p. 144) seem to have been unusually plentiful in Scot¬ 
land ; and, finally, forty-two nests of Megalestris catarrhactes 
were counted in the breeding-season at Hermaness in Unst. 
A short paper by Mr. W. Evans on the origin of the 
present colony of Great Spotted Woodpeckers in Scotland, 
in which the author inclines to the view of an English rather 
than a Scandinavian source of supply, is preceded by an 
article on the same species by Mr. Harvie-Brown, who 
elaborates and maps out for us with his usual accuracy the 
gradual extension of the bird's range since 1841 or 1851. 
In the map present summer-records and records of breeding, 
ancient records, and those of winter are duly represented by 
various signs or dates, so that we can take in the facts at a 
glance, and see for ourselves how distinct this new colony is 
Irom the old, whose breeding area lay to the north of the 
Grampians. In the letterpress the gradual extension north¬ 
ward and southward since the first nest was found in 1887 at 
Duns, in Berwickshire, is carefully traced, while a specimen 
of the schedules used in the investigation is printed for the 
guidance of others. The author furthermore discusses the 
route by which this species is likely to spread still further 
to the north, and ventures to prophecy that it will be by 
way of the Dee. 
Mr. H. B. Watt follows with a list of Scottish Heronries, 
past and present, but we are afraid that he has omitted to 
consult certain books or papers on local avifauna; Muirhead's 
f Birds of Berwickshire 5 and the articles in the f History of 
the Berwickshire Naturalists' Club' would, for instance, 
have enabled him to be more accurate with regard to some
