on a visitation of Greenland Falcons by the same and Mr. 

 Eagle Clarke; and on the rare hybrid between the Black- 

 cock and Capercaillie, with some remarks on the latter species 

 in East Lothian. 



In the July part we have a skilfully drawn-up Report on 

 Scottish Ornithology for 1909 by those energetic lady-workers 

 Misses Baxter and Rmtoul, who take the place this year of 

 Mr. Laidlaw. It will be remembered that they themselves 

 added a new species to the British, list in 1909 {Saxicola 

 pltschanka from, the Isle of May), but they call our attention 

 here to many other rare birds, too numerous to mention, 

 including Phylloscopus superciliosus on the Scottish mainland, 

 Oriolus galbula, Zonotrichia alhicollis (Flannan Islands), 

 Falco candicans, Tadorna casarca, and numerous species from 

 Fair Isle and the Isle of May. A feature in the Report is 

 the division into sections which deal with different subjects, 

 such as extension of breeding-range, nesting of the species* 

 migration, and so forth ; while the occurrences in winter are a 

 welcome addition to the usual spring and autumn records* 

 Among the latter the great invasion of the Crossbill into 

 Britain is duly chronicled and discussed. 



The Pentland Skerries have furnished a specimen of the 

 Rock-Thrush, which was sent to the Royal Scottish Museum; 

 this, Mr. Eagle Clarke says, is only the second time that 

 Monticola saxatilis has occurred in Britain, if we except 

 doubtful reports. In the ' Zoological Notes ' for July we 

 find mention of a Chough from Peeblesshire, and an 

 American Yellow-billed Cuckoo from Colonsay, besides 

 further occurrences of the Crossbill.
