52. Bryan on Birds from Molokai (Hawaiian Islands ). 
[Some Birds of Molokai. By Wm. Alanson Bryan, formerly Curator 
of Ornithology and Taxidermist in the Bishop Museum, Occ. Pap. 
Bishop Mus. vol. iv. no. 2. Honolulu, 1908.] 
With a view of obtaining materials for the series of 
Hawaiian bird-groups in the Bishop Museum,” Honolulu, 
Mr. Bryan spent two months (April 15th to June 15th, 
1907) in the mountains of Molokai. His main object was 
to get specimens of the Black Mamo ” ( Drepanorhamphus 
funereus) —“ one of the rarest of living birds,” but other 
species were not neglected, and a good series of field-notes 
was likewise put together. 
Mr. Bryan gives us a graphic account of his struggles to 
secure specimens of the much wished for bird. Several 
previous explorers had failed in doing so, and it was gene¬ 
rally supposed that the species was quite extinct. From his 
various camps on the mountains of Molokai, Mr. Bryan 
searched the wet bog-forests, which are drenched by almost 
continuous rain, for many weeks in vain. At length, when 
he and his guide were cutting their way through a particu¬ 
larly dense and unpromising jungle, they heard “a clear, 
gentle, even whistle, Ho-a,” uttered by some bird not fifty 
yards away. Mr. Bryan began to imitate the call as well as 
he could, and the curious black bird with its wonder¬ 
fully curved bill flew down, and perched in a tree within ten 
feet of him. Thus the first specimen was obtained, though it 
was most difficult, when shot, to find it in the dense herbage. 
Two fine adult male individuals were subsequently procured 
in the same district.
