Recently published Ornithological Works. 351 



fish scales are found in the stomachs of Water-Ouzels, the 

 bulk of their food consists o£ aquatic insects. 



The food of the Jay in Bohemia forms another subject of 

 investigation undertaken by Curt Loos. He finds from the 

 examination of 135 stomachs that the bulk of the food is of 

 vegetable origin, and consists chiefly of acorns, the animal 

 matter chiefly of coleopterous insects. 



The greater part of this number (pp. 35-134) is taken up 

 with the statistics of the spring migrations of various birds 

 during the years 1897 to 1903. Very copious details and 

 an elaborate series of dates are given, which we have not 

 here space to discuss, but they should be examined by 

 every serious student of migration. 



The Scottish Naturalist. 



[The ScottisLi Naturalist. Nos. 13-24 forming tlie volume for 1913. 

 Edinburgh (Oliver & Boyd).] 



Most of the ornithological articles in last year's volume 

 of the ' Scottish Naturalist ' are by the editor, Mr. Eagle- 

 Clarke. On pp. 5 and 25, in collaboration with the Duchess 

 of Bedford, he reports on migration observations on Fair 

 Isle during 1912, made pai'tly by himself and partly by 

 Mr. Wilson, the bird-watcher, and Mr. George Stout. 



From this little island, not inaptly called the British 

 Heligoland, which is only three miles by two and lies mid- 

 way between Orkney and Shetland, records of 411 species 

 have now been obtained: only 18 of these are residents. The 

 two rarities of 1912 are the Black Chat (^Saxicola leucura), 

 new to the Scotch avifauna and only once previously obtained 

 in the British Islands, and the Curlew Sandpiper, probably 

 not so uncommon, but not hitherto detected. 



In a subsequent note Mr. Clarke states that a Wagtail 

 that he obtained in May 1910 on Fair Isle turns out on 

 further examination to be an example of Motacilla flava 

 beema, an Asiatic species which had been once previously 

 recorded in the British Isles from Sussex.
