But finally I fixed its place in the avian schedule with the help of my field glass white under parts, slightly tinged with yellow, back and rump olive green, top and sides of head delicate bluish-ash; no eye-ring, no wing-bars. There is no other warbler marked quite like that.
Now the working of a single-line is entirely dependent on the telegraph, and the oven-birds, with their misplaced zeal, were continually interrupting telegraphic communication, so on the Great Southern Railway of Buenos Ayres every single telegraph-post was surmounted with a wooden box, mutely proclaiming itself the most desirable building-site that heart of bird could wish for, and silently offering whatever equivalents to a gravel soil and a southern aspect could suggest themselves to the avian intelligence.
Even the sounds of the night are different. The chuckles and cackles of the spotted owlets no longer fill the welkin; the silence of the darkness is broken in the mountains by the low monotonous whistle of the pigmy-collared owlet. The eye equally with the ear testifies to the traveller that when he has reached an altitude of 5000 feet he has entered another avian realm.
Moving the flock to fresh runs and the administration of intestinal antiseptics are the only effective lines of treatment. AVIAN TUBERCULOSIS. Tuberculosis of poultry is a serious disease in some countries. Poultry usually contract tuberculosis by contact with a tubercular bird, and not from other domestic animals and man.
If it were in my power to show the reader a colored plate of each species now being exterminated by the feather trade, he would be startled by the exhibit. That the very choicest birds of the whole avian world should be thus blotted out at the behest of vain and heartless women is a shame, a disgrace and world-wide loss.
Let me repeat; this is of the very smallest importance in all the practical affairs of life, or indeed in relation to anything but philosophy and wide generalisations. But in philosophy it matters profoundly. If I order two new-laid eggs for breakfast, up come two unhatched but still unique avian individuals, and the chances are they serve my rude physiological purpose.
No gills ever develop in these, but the great arteries run to them, and indeed to all parts of the embryo, on almost precisely the same general plan as in the adult fish. Only later is the definite avian circulation gradually acquired. This law is even more strikingly illustrated in the embryonic development of the vertebral column and skull, if we had time to trace their development.
You would naturally suppose that if any bird had need of two hind toes, it would be the nuthatch; but the result proves that, after all, Nature had her wits about her when she evolved this avian family. The world over, there are twenty distinct species of nuthatches known to scientific observers, but only four of them are natives of America.
After flitting about among the bushes for a minute or two, chirping his protest at my presence, he descended into the copse below and disappeared. Of course, any student of birds would have supposed that he had gone down near the nest to feed his bairns, and that he only needed to go and examine the place to discover the little avian secret.
He evidently subserves some useful purpose in the avian community, or he would not be treated with so much consideration. A young cowbird that I purloined from the nest and tried to rear by hand did not prove a pleasant pet. He was placed in a large cage with several other kinds of young birds.
