PREFACE. 



The present number of ' The Ibis ' is the two hundred 

 and twenty -fourth, and completes the tenth series, and 

 with its issue the Editor wishes to thank his numerous 

 contributors for the support they have given him in 

 these difficult times. The Editor believes that the 

 papers and other communications contained in the 

 present series will compare favourably with those 

 of the previous series, notwithstanding the unprece- 

 dented events which are taking place throughout the 

 world, and which have turned men's minds away 

 from the peaceful pursuits of ornithological and 

 other scientific researches. 



It is his hope, as doubtless it is that of all the 

 other Members of the British Ornithologists' Union, 

 that peace will come soon, and we shall all be able to 

 give our undivided attention to our favourite study — 

 the advancement of Ornithology.
