170 FEMALE GOLDEN-WINGED WARBLER. 
The specimen of the Rocky Mountain antcatcher we are de- 
scribing is a male, shot in the month of July, and possibly 
not adult. As it is the only one brought by Major Long’s 
party, we cannot determine the extent or nature of the varia- 
tions the species may undergo from age, sex, or season. 
The note of this bird is peculiar, resembling the harsh voice 
of the terns. It inhabits the sterile country bordering on the 
river Arkansaw, in the neighbourhood of the Rocky Mountains, 
where it is frequently observed hopping on the ground, or flit- 
ting among the branches and weatherbeaten, half-reclining 
trunks of a species of juniper: when it flies among the crooked 
limbs of this tree, it spreads its tail considerably, but was never 
seen to climb. ‘They were generally observed in small asso- 
ciations of five or six individuals, perhaps composing single 
families.

Tne female of this pretty little warbler, hitherto unknown to 
any naturalist, is now figured and described for the first time. 
For the opportunity of presenting it to the reader, we are
