The thick hedge mentioned is a favourite resort of blackbirds, and on a warm May morning, after a shower—they are extremely fond of a shower—half-a-dozen may be heard at once whistling in the elms. They use the elms here because there are not many oaks; the oak is the blackbird's favourite song-tree. There was one one day whistling with all his might on the lower branch of an elm, at the very roadside, and just above him a wood-pigeon was perched. A pair of turtle-doves built in the same hedge one spring, and while resting on the gate by the roadside their "coo-coo" mingled with the song of the nightingale and thrush, the blackbird's whistle, the chiff-chaff's "chip-chip," the willow-wren's pleading voice, and the rustle of green corn as the wind came rushing (as it always does to a gateway).
Goldfinches come by occasionally, not often, but still they do come. The rarest bird seems to be the bullfinch. I have only seen bullfinches three or four times in three seasons, and then only a pair. Now, this is worthy a note, as illustrating what I have often ventured to say about the habitat of birds being so often local, for if judged by observation here the bullfinch would be said to be a scarce bird by London. But it has been stated upon the best authority that only a few miles distant, and still nearer town, they are common.
The road now becomes bordered by elms on either side, forming an irregular avenue. Almost every elm in spring has its chaffinch loudly challenging. The birdcatchers are aware that it is a frequented resort, and on Sunday mornings four or five of them used to be seen in the course of a mile, each with a call bird in a partly darkened cage, a stuffed dummy, and limed twigs. In the cornfields on either hand wood-pigeons are numerous in spring and autumn. Up to April they come in flocks, feeding on the newly sown grain when they can get at it, and varying it with ivy berries, from the ivy growing up the elms. By degrees the flocks break up as the nesting begins in earnest.
Some pair and build much earlier than others; in fact, the first egg recorded is very little to be depended on as an indication. Particular pairs (of many kinds of birds) may have nests, and yet the species as a species may be still flying in large packs. The flocks which settle in these fields number from one to two hundred. Rooks, wood-pigeons, and tame white pigeons often feed amicably mixed up together; the white tame birds are conspicuous at a long distance before the crops have risen, or after the stubble is ploughed.
I should think that the corn farmers of Surrey lose more grain from the birds than the agriculturists whose tenancies are a hundred miles from London. In the comparatively wild or open districts to which I had been accustomed before I made these observations I cannot recollect ever seeing such vast numbers of birds. There were places, of course, where they were numerous, and there were several kinds more represented than is the case here, and some that are scarcely represented at all. I have seen flocks of wood-pigeons immensely larger than any here; but then it was only occasionally. They came, passed over, and were gone. Here the flocks, though not very numerous, seem always to be about.
Sparrows crowd every hedge and field, their numbers are incredible; chaffinches are not to be counted; of greenfinches there must be thousands. From the railway even you can see them. I caught glimpses of a ploughed field recently sown one spring from the window of a railway carriage, every little clod of which seemed alive with small birds, principally sparrows, chaffinches, and greenfinches. There must have been thousands in that field alone. In autumn the numbers are even greater, or rather more apparent.
One autumn some correspondence appeared lamenting the scarcity of small birds (and again in the spring the same cry was raised); people said that they had walked along the roads or footpaths and there were none in the hedges. They were quite correct—the birds were not in the hedges, they were in the corn and stubble. After the nesting is well over and the wheat is ripe the birds leave the hedges and go out into the wheatfields; at the same time the sparrows quit the house-tops and gardens and do the same. At the very time this complaint was raised, the stubbles in Surrey, as I can vouch, were crowded with small birds.
If you walked across the stubble flocks of hundreds rose out of your way; if you leant on a gate and watched a few minutes you could see small flocks in every quarter of the field rising and settling again. These movements indicated a larger number in the stubble there, for where a great flock is feeding some few every now and then fly up restlessly. Earlier than that in the summer there was not a wheatfield where you could not find numerous wheatears picked as clean as if threshed where they stood. In some places, the wheat was quite thinned.
Later in the year there seems a movement of small birds from the lower to the higher lands. One December day I remember particularly visiting the neighbourhood of Ewell, where the lands begin to rise up towards the Downs. Certainly, I have seldom seen such vast numbers of small birds. Up from the stubble flew sparrows, chaffinches, greenfinches, yellow-hammers, in such flocks that the low-cropped hedge was covered with them. A second correspondence appeared in the spring upon the same subject, and again the scarcity of small birds was deplored.
So far as the neighbourhood of London was concerned, this was the exact reverse of the truth.
