472, THE ZOOLOGIST. 
is known—so far as this country is concerned—while the locality 
at which the observations have been made has been properly 
suppressed. The photographs of this bird and its eggs in situ 
are, as believed by Mr. Bickerton, ‘‘ the first of this rare and 
interesting bird that have ever been taken or published in the 
British Isles.”’ 
Report on the Immigrations of Summer Residents in the Spring of 
1911; also Notes on the Migratory Movements and Records 
recewed from Lighthouses and Light-vessels during the 
Autumn of 1910. By the Committee appointed by the 
British Ornithologists’ Club. Witherby & Co. 
Taxis important publication forms vol. xxx. of the Bulletin of 
the British Ornithologists’ Club, and is edited by W. R. Ogilvie- 
Grant. On the migration of birds it is an astounding collection 
and compilation of reports and observations made by trustworthy 
authorities, well arranged, properly condensed, and conveni« ily 
published in distinct sections. One sometimes wonders at the 
face value of many published observations ; an answer is sup- 
plied by this Report, where each recorded item of avian appear- 
ance is, as it were, passed through a great ornithological clearing- 
house, and appears in its proper registry. It is often said that 
naturalists are not business men; it would be weil if many — 
yearly financial records were prepared with the discretion, 
method, and fulness of this Report. Mr. Ogilvie-Grant would 
have made a great accountant; it is a matter of satisfaction, 
however, that he presides over these annual avian migration 
reports, and remains an ornithologist. © 
The thanks of all who study this fascinating subject are also 
‘‘due tothe Master and Elder Brethren of the Trinity House for 
the continuance of their permission to enlist the services of the 
light-keepers,”” and we would add the remark—entomologists, 
please copy.
