are accustomed, within a short time of leaving the nest, to thrust their bills into the mouths of their parents and suck out what they have brought them. As I have found their nests as late as the 12th of July, I do not doubt but that they frequently and perhaps usually raise two broods in the season. "This Humming Bird is extremely fond of tubular flowers, and I have often stopped to observe his manœuvres among the blossoms of the trumpet flower. When arrived before a thicket of these in full bloom, he poises or suspends himself on wing for the space of two or three seconds so steadily that his wings become invisible or only like a mist, and you can plainly distinguish the pupil of his eye looking round with great quickness and circumspection; the glossy golden green of his tail and the fire of his throat dazzling in the sun form altogether a most beautiful appearance. When he alights, which he frequently does, he always prefers the dry twigs of a tree or bush, where he dresses and arranges his plumage with great dexterity. His only note is a single chirp, not louder than that of a small cricket or grasshopper, generally uttered while passing from flower to flower, or when engaged in fight with his fellows; for when two males meet at the same bush or flower a battle instantly takes place, and the combatants ascend in the air, chirping, darting, and circling round each other till the eye is no longer able to follow them--the conqueror, however, generally returns to the place to reap the fruit of his victory. I have seen him attack and, for a few moments, tease the King Bird, and have also seen him in his turn assaulted by a humble bee, which he soon put to flight. "This beautiful and delicate species is extremely susceptible of cold, and if long deprived of the animating influence of the sunbeams droops and soon dies. A very fine male which was brought to me I put into a wire cage, and placed it in a retired, shaded part of the room. After fluttering about for some time, the weather being uncommonly cool, it clung to the wires and seemed in a torpid state for the whole forenoon. No movement of breathing could be perceived on the closest inspection, though at other times this is remarkably observable, the eyes were shut, and when touched with the finger it gave no signs of life or motion. I carried it out into the open air, and placed it directly in the rays of the sun; in a few seconds respiration became very apparent, the bird breathed faster and faster, opened its eyes, and began to look about with as much seeming vivacity as ever. After it had completely recovered it flew off to the top of a pine-tree, where it sat for some time dressing its disordered plumage, and then shot off like a meteor.
