some lights to aquamarine, in others to bluish green, and in others

to golden green; all the upper surface and wing-coverts golden

wings purplish brown; tail purplish black, glossed with dark green;

behind the eye a spot of white, and on the cheeks a streak of grey;

_Hab._ S. Brazil, Paraguay, and Argentina.

Of the three Humming-birds which visit the vicinity of Buenos Ayres in

the summer months, Mr. Durnford tells us this is the rarest. It

is occasionally seen in the riverain wood, and like the other two

(_Hylocharis sapphirina_ and _Chlorostilbon splendidus_) may generally

be found hovering over the flowers of the Ceiba-tree--a species of

_Erythrina_.

Further to the north this species would seem to be more abundant.

Dr. Burmeister met with it near Tucuman and Paraná, and at one time

described the young birds obtained in the latter locality as of a

distinct species (_Campylopterus inornatus_), an error which he

subsequently corrected (_cf._ P. Z. S. 1864, p. 466). White procured

it in the city of Catamarca in August 1880.

Mr. Barrows has published the following interesting account of his

observations on this species in Entrerios (Auk, 1882, p. 21):--

"Early in September, at Concepcion, when the orange-trees are just

whitening with blossoms, these magnificent Humming-birds arrive from

the north, and may occasionally be seen about the orange-trees in any

garden, as well as about blossoming trees elsewhere. The males seemed

for some reason to be much less abundant than the females, hardly more

than a dozen being seen in an entire season. They probably nest in

November and December, and leave for the north again in February or

March. A nearly finished nest, found November 17, was very similar to

that of our own Ruby-throat (_Trochilus colubris_) but larger, and was

built in the compound fork of a large limb at a height of over 25 feet

from the ground. It was deserted soon after, perhaps as a result of

my examination. Ten days later another nest was found saddled on the

topmost horizontal limb of a dead and moss-grown stub; only about seven

feet from the ground, and exposed to the full force of the sun.

This nest contained two eggs nearly ready to hatch. Both nests were

beautifully covered with lichens, and the last was lined with the finest

of vegetable down. The female made several angry rushes at me before

the nest was touched, but as soon as she saw that it was discovered

became so shy that it was difficult to secure her. The male was not seen

at all. I once saw a bird of this species attack and put to rout a wild

dove which passed near it while feeding, and though the dove made every

effort to escape, the Hummer not only kept up with it easily, but darted

above and below it as well, and finally both went out of sight in the

distance together."
