It is very generally believed that the singing-birds are confined to temperate latitudes, and that the tropical birds have not the gift of song. That this is an error is apparent from the testimony of travellers, who speak of the birds in the Sandwich Islands and New Zealand as singing delightfully, and some fine songsters are occasionally imported in cages from tropical climates. The origin of this notion may be explained in several ways. It is worthy of notice that within the tropics the singing season of different species of birds does not occur at the same time. One species may be musical in the spring, another in summer, and others in autumn and winter. When one species, therefore, has begun to sing, another has ceased, so that, at whatever time of the year the traveller stops, he hears but few birds engaged in song. In the temperate latitudes, on the contrary, as soon as the birds arrive, they commence building their nests, and become musical at the same time. If a stranger from a tropical climate should arrive in this country in the spring, and remain here during the months of May and June, he would hear more birds singing together than he ever heard at once in his own clime; but were he to arrive about the middle of July, when the greater number of our birds have discontinued their songs, he would probably, if he knew the reputation of the Northern birds, marvel a little at their silence. If there are as many birds singing at one time during the whole year, in the hot climates, as we hear in this country in the latter half of summer, the greater average would appear to be on the side of the former. It may also be remarked, that the singing-birds of the tropics are not so well known as those of temperate latitudes which are inhabited by civilized men. The savages and barbarians, who are the principal inhabitants of hot countries, are seldom observant of the habits or the voices of the singing-birds. A musician of the feathered race, as well as a harpist or violinist, must have an appreciating audience, or his powers can never be made known to the world. But even with the same audience, the tropical singing-birds would probably be less esteemed than songsters of equal merit in the temperate latitudes; for, amid the stridulous and deafening sounds made by the insects in warm climates, the notes of birds would be scarcely audible.
