Its proper song commences very early in spring, and is continued until June or later. This must be the song which the poet had in view when he sang:--
Then as a little helpless innocent bird, That has but one plain passage of few notes, Will sing the simple passage o'er and o'er, For all one April morning, till the ear Wearies to hear it. --TENNYSON.
It consists of from ten to twelve notes of the same tone, and about the same length, with the last but one elevated and accented, uttered rapidly at short intervals, and without the least variation.
In Germany, this bird is so great a favourite that not a single tone of its voice has escaped the experienced ears of bird-fanciers. In some parts of Holland and the north of France, the passion for song Chaffinches amounts to a frenzy. Philharmonic societies are formed, whose exclusive object is to educate Chaffinches, and to organize vocal combats. The combatants, each in his cage, are placed a few yards from each other. One of them utters his strain, which is replied to by the other; strict silence is imposed on the spectators, lest the attention of the birds should be distracted by their remarks or applause. The contest proceeds as long as the birds continue to utter their notes of defiance, and the victory is adjudged to the one who has the last word. The price paid for a bird of mark, and the pains bestowed on the capture of any bird which in its wild state holds out promise of being an apt pupil, are past belief, and the cruelty practised in producing a perfect songster I cannot bring myself to describe. After all, Bechstein's translator says that the notes of the wild Chaffinches in England are finer than any cage ones he has heard in Germany. English bird-fanciers, without going so far as their German brethren, profess to distinguish three variations of song in the Chaffinch.
The nest of the Chaffinch is an exquisite piece of workmanship, composed of moss, dry grass, fine roots felted together with wool, decorated externally with scraps of white lichens, and lined with hair and feathers. It is placed sometimes in the fork of a tree, sometimes against the bole, but more frequently than anywhere else it is built in among the twigs of an apple-tree; but in every case it is attached to its support by wool interwoven with the other materials. The Chaffinch usually lays five eggs.
