NOTICES OF NEW BOOKS. 159 



followed in other local ornithological books, for we seem to recog- 

 nize the haunts of various species, and the tourist, as well as the 

 ornithologist, should take this volume with him when visiting 

 Man. 



The Twite has been found breeding both in the north and 

 south of the island, and is described by Mr. Ealfe as "an 

 inhabitant of mountains and high wild coast-lands." Corvus 

 frugilegus is now an abundant species, and our author enumerates 

 twenty Manx rookeries. The Chough is reported " as more 

 frequent in Man than is perhaps generally supposed," the account 

 of this bird being given in a very full and interesting manner ; 

 and we re-echo the plea made by Mr. Ealfe who, recognizing its 

 may be inevitable extinction " in the course of natural law," 

 earnestly asks " all professing interest in the ornithology of 

 Britain to abstain from the encouragement of any action (punish- 

 able also by Manx law) which may accelerate that extinction in 

 this perhaps the most easily accessible of its British haunts." 



Report on the Immigrations of Summer Residents in the Spring of 

 1905. By " The Committee appointed by the British 

 Ornithologists' Club." Witherby & Co. 



This publication, which forms vol. xvii. of the ' Bulletin 

 of the British Ornithologists' Club,' is to be obtained sepa- 

 rately, and should be in the hands of all students and lovers 

 of British birds. The Committee consisted of Dr. F. G. Pen- 

 rose (Chairman), M. J. Nicoll, N. F. Ticehurst, H. F. Witherby, 

 and J. L. Bonhote (Secretary). The immigrations of twenty- 

 nine birds are reported, illustrated by thirty-two maps, and the 

 outlay made by the Club should be returned, for it is almost 

 a duty to acquire this information on an intricate subject, and 

 to support by purchase so excellent a Pieport. For this reason 

 we have thought it unfair to make quotations from its pages, 

 merely confining ourselves to the remark that one may gain a 

 very considerable appreciation of the method and extent of this 

 immigration by a study of the maps alone.
