NOTES ON BIRDS COLLECTED IN MINDORO AND 
IN SMALL ADJACENT ISLANDS. 
By Riciarp C. McGrecor, 
(From the Zoélogical Section of the Biological Laboratory, Bureau of Science.) 
I am indebted to Dr. EK. H. Porter, contract surgeon, United States 
Army, for permission to publish the following lists of birds which are 
based upon collections made by him in the vicinity of Bulalacao, Min- 
doro, and on the small Islands of Sibay, Caluya, Libagao, and Semirara, 
off the southeast coast of Mindoro. A few species are recorded from 
Tambaron, but as this island is very small and but 5 miles off the 
coast of Mindoro near Bulalacao, it does not seem necessary to deal with 
it separately. 
Dr. Porter was stationed at Bulalacao from May 19, 1905, to Feb- 
ruary 24, 1906, and most of his specimens were obtained in the vicinity 
of that town. No visits were made to the higher mountains of Mindoro 
and information concerning the birds of the smaller islands was gained 
during short visits to them. 
The collection contains specimens of all the species hereinafter  re- 
corded in the list of species collected and all of the new records for 
Mindoro are based upon skins examined by me. For the lists of species 
from the small islands (Semirara, Caluya, Sibay, Libagao) I have, in 
most instances, depended upon the field identification made by Dr. Porter, 
as these species can be easily named on sight. 
The ultimate destination of this collection is not known to me, but 
as Dr. Porter has taken it to the United States it will probably find 
its way into some one of the larger museums in that country. 
The Hand-List, referred to in the text and footnotes, is that by 
McGregor and Worcester,’ issued January, 1906. 
The sequence of genera and the nomenclature of the present paper 
are the same as in that publication. 
Dr. Porter obtained specimens of thirteen species not hitherto re- 
corded from Mindoro; their points of interest are mentioned in the 
list of species collected. ;
