Avicultural Magazine. 



[Tlie Avicultural Magazine, being the Joumial of the Avicultural 

 Society for the study of Foreign and British Birds in freedom and 

 captivity. 3rd ser. Vol. x., 14 nos. Nov. 1918 to Dec. 1919.] 



The volume of the 'Avicultural Magazine^ for last year 

 contains fourteen numbers, so as to make each volume in 

 future correspond to the calendar year — an excellent change. 

 We also notice that a decided efibrt is being made to amal- 

 gamate the Magazine with ' Bird Notes/ the organ of the 

 Foreign Bird Club. We \\n\)c that this may be brought 

 about, as it will then be possible to concentrate the material 

 and effect considerable economies by publishing only one 

 magazine instead of two, for which there seems hardly 

 enough demand. 



The volume before us contains a number of articles from 

 former contributors, such as Dr. Butler, ]\Ir. W. Shore 

 Baily, and Mr. Astley, but we regret to notice how fre- 

 quently the editor, Mr. Graham Renshavv, has had to resort 

 to paste and scissors, and to reprint articles from American 

 and Australian sources. 



Dr. Butler and Dr. \. C. L. van Somei en run a tilt on the 

 old controversy of the change of colour in grown feathers, 

 and discuss the cases of Pyromelana and the turacin pigment 

 of tlie Toiiracos. Mr. Hopkinson concludes his account of 

 the Pigeons of the Gambia^ and Lieut. Delacour writes on 

 the flourishing state of the Zo;)lc)gical Gardens at Cologne, 

 which he contrasts with his own devastated aviaiies on iiis 

 estate at Villers-Bretonneux. An interesting note by 

 Miss E. Maud Knobel deals with the moult of the outer 

 tail-feathers of an Alexandrine Parrot, of which careful 

 record has been kept each year from 1915 to 1919. During 

 this time the date of shedding has advanced from June 8 

 to July 8, and the length of the feathers has increased 

 from 13| and 13^ inches right and left in 1915 to 14i and 

 14^ inches in 1919.
