438 Mr. D. A. Bannerman on the Distribution of 



XXVII. — The Distribution mid Nidijication of the Tubinares 

 in the North Atlantic Islands. By David A. Bannerman 

 B.A., M.B.O.U., F.R.G.S. 



(Plate X VII.) 



The following paper is an attempt to determine tlie local 

 range of the several species and subspecies of Petrels, Shear- 

 waters, and Fulmars which occur in the north Atlantic 

 Islands ; also to get together all the data which have 

 been published with reference to the nesting-seasons in the 

 various islands, and to give, in as concise a form as possible, 

 a review of all the work done in the past relating to the 

 Tubinares in the islands under discussion. 



Besides many valuable papers written in English, many 

 contributions have been made by French, German, Italian, 

 Spanish, and Portuguese writers. Every one of these papers 

 I have had carefully translated, and I hope that I have not 

 overlooked any paper having an important bearing on the 

 subject. A complete list of the various authors and works 

 consulted is appended on page 446. For the most part I have 

 only made use of papers when the writers have personally 

 visited and made observations in the north Atlantic Islands. 

 It is needless to add that without these papers it would have 

 been utterly impossible to arrive at any conclusions regarding 

 either the distribution or nesting-habits of the various birds. 

 I should like particularly to acknowledge and call attention 

 to the immense value of Padre Schmitz's " Diary Notes ^' 

 on the Petrels inhabiting the Madeira Group of islands. 

 This ornithologist has kept, for a period of over sixteen 

 years, a concise and accurate record of the birds — particu- 

 larly the Petrels — which have come to his notice during his 

 I'csidence in the island of Madeira, and has acquired a most 

 valuable collection of birds, which is exhibited in his 

 museum at Funchal.
