HUMMINGBIRDS: BROAD-BILLED HUMMINGBIRD 369 
Nest— In small sycamore or maple (Willard), and red fir 50 feet from the ground 
(Howard). (Two found by Henshaw and Price) in alder and walnut, 20 and 10 feet 
from the ground; made of mosses, covered with lichen fastened with spider webs, 
and of silky plant fibers coated with lichen and lined with down and one or two 
feathers. Eggs: 2, white. 
Food. —Small insects, found on honeysuckles, agaves, and other plants. 
General Habits. —The flight of the Rivoli is erratic at times, 
Mr. F. H. Fowler says, like that of a hummingbird moth or of a bat, and 
it even soars or sails occasionally, for a few feet (1903, p. 107). 
An interesting account of a young Rivoli and its mother is given 
us by Mr. F. C. Willard. The young one was discovered after a heavy 
rain on the ground nearly drowned. Warmed in the hands it soon 
revived and was fed with honey on the tip of a toothpick. The anxious 
mother followed it into the house and after a little hesitation “alighted 
on the tip of the fingers of the hand which held the youngster, and fed 
it/’ (1909a, pp. 102-103).

State Records. —When Mearns was collecting along the southern boundary 
of New Mexico,on August 31, 1893, he took a specimenof the Broad-billed Humming¬ 
bird on the Guadalupe Mountains (Cloverdale range) in the extreme southwestern 
part of the State, and this is the only record of the bird for New Mexico. As the 
species is known to breed a hundred miles to the westward in the Huachuca Moun¬ 
tains of Arizona, it is, of course, possible that it breeds in the Guadalupe Mountains, 
but the fact that it has not been found by subsequent collectors and the further fact 
that it is not known to occur at any time of year in the neighboring Chiricahua Moun¬ 
tains, make it probable that the specimen taken by Mearns was merely a wan¬ 
derer migrating from its breeding range in Arizona.—W. W. Cooke.
