A CONTRIBUTION TO THE ORNITHOLOGY OF THE 
ORINOCO REGION. 
Bv George K. Cherrie. 
This paper is based chiefly on specimens in the collection of the 
Museum of The Brooklyn Institute of Arts and Sciences, obtained by 
the writer, together with his field notes on the same.^ It includes, how- 
ever, observations on the specimens sent to the American Museum of 
Natural History from the vicinity of Ciudad Bolivar on the Orinoco 
and various points on the Caura River b}' Mr. Samuel M. Klages. 
In 1905 collections were made by the writer for the 
Brooklyn Museum in the vicinity of Ciudad Bolivar and the 
village of Caicara covering the period from April 3rd to June 
24th inclusive. In 1907 collecting was carried on in the same local- 
ities as in 1905, and in addition at various points on the River San 
Feliz, near its junction with the River Cuchivero, a tributary of the 
Orinoco, entering that stream some forty miles below the village of 
Caicara. Also a week's time was spent in the middle delta region of 
the Orinoco at the village of Las Barrancas. The collecting in 1907 
covered the period between April 6th and August 7th inclusive. In 
addition, however, to the notes on specimens in the Brooklyn Aluseum 
collection, there have been added certain notes and observations on 
species collected and observed by Stella M. Cherrie and the writer in 
the valley of the Orinoco in 1897, 1898, and 1899, while engaged in 
collecting birds for the Tring Museum, England. Thus not only are 
'The manuscript for this paper was completed some five or sue years ago, and passed out of the 
author's hands at that time. After some vicissitudes, it was being pubUshed under the editorship of 
the late Edward L. Morris, acting Curator-in-Chief of the Broolilyn Museum. His untimely death left 
It partly in page proof and partly in galley proof. The old proof sheets have been placed in the writer's 
hands, and recently published investigations of various students of tropical American ornithology have 
made considerable revision necessary. The paper, therefore, is not as complete as might be desired, nor does 
it represent the most recent views on classification. 
I wish to express my sincere gratitude to Mr. Waldron DeWitt Miller for his patient, careful work 
in reading the proof. To Dr. J. A. .^Uen and Dr. Frank M. Chapman I am also indebted for granting me 
full use of the collections in the .American Musc-um of Natural History. — The ..^uthor.
