1897 MERRILL, Birds of Fort Sherman, Idaho. 349 
brought together by Dr. C. Hart Merriam in Number 5 of the 
‘North American Fauna’ series of the Department of Agriculture.! 
This report enumerates 156 species and throws much light on the 
summer fauna of Southern and Central Idaho. The present paper 
may be considered as supplementing it as to the winter avifauna 
and that of the northern part of the State. Since the publication 
of Dr. Merriam’s paper Prof. B. W. Evermann made a small col- 
lection in the Sawtooth range district in September, 1894, and 
has kindly allowed me to look over his MS. notes. Two male 
Pipilos, identified as probably megalonyx, is the first record of this 
species in Idaho. 
The following observations were made from November, 1894, 
until December, 1896. One hundred and sixty-seven species are 
enumerated, of which fifty, to each of which an asterisk is pre- 
fixed, have not, so far as I am aware, been previously taken in 
Idaho. I desire to express my obligations to Mr. William Brewster 
for kindly identifying some of the species ; his opinions are incor- 
porated in the text. 
* ZEchmophorus occidentalis.— A single specimen taken. 
* Colymbus holbeelii.— Resident but most common during migrations. 
A nearly completed nest was found in the marsh on May 18; when again 
visited on June 3 it contained four eggs, but was deserted, owing probably 
to the rapid fall of the lake level leaving it high and dry. The parents 
continued in the vicinity throughout the summer and probably bred again. 
1 One paper has been overlooked by Dr. Merriam in the preparation of his 
list. It has the somewhat misleading title of ‘The Fauna of Montana Terri- 
tory,’ by J. G. Cooper, and may be found in the ‘American Naturalist,’ IT, 
pp. 596-600; III, pp. 31-35; 73-84; also p. 224. The context shows that 
certain species were taken or observed in what is now the State of Idaho. Of 
such not included in the Merriam list are, to quote the names as given, Falco 
columbarius, Turdus nevius, Stalia mexicana, Securus noveboracensis, Setophaga 
ruticilla, Sitta pygme@ea, Parus rufescens, Curvirostra antericana var. mexicana, 
Curvirostra leucoptera, Corvus caurinus, Columba fasciata, Ectopistes migra- 
torius. It may be remarked in regard to these species that the Water Thrush 
was undoubtedly the zotadz/is form; the Crossbill Z. curvirostra minor, and 
the Crow C. americanus, and not what is now understood as caurinus. 
Columba fasciata was not satisfactorily identified. 
Seiurus aurocapillus should also be added to the avifauna of Idaho, as 
Dr. Cooper states (Bull. N. O. C., II, 1877, p. 91) that it has been « recently 
recorded from Idaho.” I do not know where this record is to be found.
