77. North on the Xtsts and Eggs of Australian Birds. 



[Nests and Eg-gs of Birds found breeding in Australia and Tasmania. 

 By Alfred J. North, C.M.Z.S. Vol. iii. Part 1 * Sydney, 1911.] 



We liave received another part of this valuable work. In 

 it tlie account of the Australian Cuckoos is finished and 

 that of the Parrots is comuieuced. Many interesting parti- 

 culars are given concerning the Ijreeding-habits of the 

 Australian Cuckoos. It appears to be now quite settled 

 that Cucu'ns inornatus m some cases feeds its own young. 

 A startling picture, taken from a photograph, is given of 

 "Fred" (an Australian aloriginal) taking a nest of the 

 Blue-tailed Lorrikcet. 



78. Percival on European Migrants in British East Africa. 



[European Migrants in British East Africa. By A. B. Percival. 

 Joum. E. Afr. Xat. Hist. Soc. vol. i. p. 101 (1911).J 



Tliis is a nicely written paper upon a very interesting 

 subject, and Mr. Percival deserves our thanks for calling 

 attention to it. British East Africa, he reminds us, is half- 

 way between the winter and summer residences of many 

 European migrants, and a series- of dates when birds pass 

 through it on their southern joiirney, and again on their 

 return trip, would be of great importance. Mr. Percival, 

 whose business it is to wander about the country as Game- 

 warden, has excellent opportunities for occasionally turning 

 his attention to Birds, and invites bis brother-members of 

 the Natural History Society of East Africa and Uganda to 

 aid bim in this task. We trust that they will follow his 

 excellent addce. 



.Mr. William Sclater read a paper on South-African 

 migration before the British Association in 1905, and 

 Mr. Percival copies Mr. Sciater's list of migrants and 

 makes remarks on it. At least ninety species of the South- 

 African Avifauna are known to go north every year to breed 

 in Northern Euro])e and Asia, and must necessarily pass 

 through Africa on their journey. It is probable that a large
