Works consulted. The literature thus placed at our disposal included not 

 only general works and monographs, but a very large number of foreign and native 

 publications on Local Faunas, all of which have been consulted with varying results. 



Good use has been made of periodical literature, foreign and native, which has 

 proved to be the richest source of supply. In addition to consulting articles in the 

 Ibis, Ornis, Ornith. Monatsberichte, Ornith. Monatsschrift, Journal fiir Ornithologie, 

 Aquila, Ornith. Jahrbuch, and others referred to in the Zoological Record, it has been 

 thought advisable to make a complete independent search through all the published 

 volumes of the following periodicals : Zoologist (1843- ), Field (1853- ), Scottish 

 Naturalist (1871-92), and its sequel the Annals of Scottish Natural History, Irish 

 Naturalist (1892- ), the North of England Naturalist, British Birds (1907- ), 

 Auk (1884- ), preceded by the Bulletin of the Nuttatt Ornith. Club (1876-83), the 

 Zoologisches Garten (1858-1905), now the Zoologische Beobachter (1906- ), Berajah, 

 and the new periodical, Revue francaise d* Ornithologie. 



Bibliography of the Preliminary Notes. For the Preliminary Notes on 

 Migration and Distribution the following have proved of special value : The 

 Migration Reports published under the auspices of the British Association, the 

 Migration Reports published in the Bulletins of the British Ornithological Club, the 

 Catalogue of Bird# in the British Museum, Mr. Eagle Clarke's Notes in the Annals 

 of Scottish Natural History, Mr. R. M. Barrington's The Migrations of Birds at Irish 

 Light Stations, 1900, E. Hartert, Vogel der Paldarktischen Fauna (in process of 

 publication), F. C. R. Jourdain, Eggs of European Birds (in process of publication), 

 the Additions to our Knowledge of British Birds, by H. F. Witherby, and N. F. 

 Ticehurst in British Birds, vols. i. and ii. (1907-9), the Manual of Howard Saunders, 

 Ussher and Warren's Birds of Ireland, Gatke, Vogelwarte Helgoland, Dr. Thiene- 

 mann's reports from Rossitten, published in the Journal fur Ornithologie, and of 

 course Naumann and Dresser. To these must be added a number of Local Faunas, 

 too numerous to mention. 



For Oology the chief works consulted besides that of Jourdain already 

 mentioned are Dresser's Eggs of the Birds of Europe, the large German works 

 of Thienemann and Baedeker, and the smaller work by Rey on the Eggs of the 

 Birds of Middle Europe. 



The information given in the remaining Sections (4-6) of the Preliminary 

 Classified Notes, dealing with nidification, incubation, food, etc., has been sought 

 throughout the whole range of ornithological literature, periodical and other.
