The Cora Humming-bird was discovered in March 
1823., by MM. Lesson and Gamot, the naturalists 
who accompanied the Coquille in her exploratory voy- 
age round the world, and a description and plate was 
first published in the zoological volume illustrating the 
novelties which occurred during it. 
The Cora inhabits the sloping banks of the elevated 
country lying between Callao and Lima, where the 
surface is low and marshy, and large portions are 
covered with salt, crystallized by the heat, on which 
there is little vegetation, and where the foliage is of a 
hue dull and glaucous. This splendid species is seen 
constantly on the wing, and seldom alights upon any 
of the blossoms. 
The whole length of this little bird is about five 
inches five lines, of which the tail makes three inches
