Every four or five minutes a chaffinch sings close by, and another fills the interval near the gateway.
How curious is the structure of the nest of the goldfinch or chaffinch!
The chaffinches called cheerfully on the plum-trees and sang in the early morning.
The daisies and the dandelions were still tightly shut, and in the hedgerow a half-awakened chaffinch hopped from twig to twig, too sleepy to chirrup.
Wherever a group of other trees rose amid the firs, the loud chirp of the chaffinch was heard, or the eager twitter of some little newly-wedded birds, disputing about the position of their nest.
Other species observed near the poison sites included rabbits, hares, foxes, roe, fallow and red deer and very small birds, mostly greenfinches and chaffinches.
It included such birds as the hedge sparrow, song thrush, linnet, chaffinch and moorhen.
In all, 20 chaffinches were used in these experiments.
