The seasonal movements of the strict migrants are little noticed in

London; there are few such species that visit, fewer still that remain

any time with us. And when they come we scarcely see them: they are not

like the residents, reacted on and modified by their surroundings, made

tame, ready to feed from our hands, to thrust themselves at all times

upon our attention. Nevertheless we do occasionally see something of

these shyer wilder ones, the strangers and passengers; and in London,

as in the rural districts, it is the autumnal not the vernal migration

which impresses the mind. Birds are seldom seen arriving in spring.

Walking to-day in some park or garden, we hear the first willow-wren's

delicate tender warble among the fresh April foliage. It was not heard

yesterday, but the small modest-coloured singer may have been there

nevertheless, hidden and silent among the evergreens. The birds that

appear in the autumn are plainly travellers that have come from some

distant place, and have yet far to go. Wheatears may be seen if looked

for in August on Hampstead Heath, and occasionally a few other large

open spaces in or near London. In September and October swallows and

martins put in an appearance, and although they refuse to make their

summer home in inner London, they often come in considerable numbers

and remain for many days, even for weeks, in the parks in autumn.

It has been conjectured that the paucity of winged insect life in London

is the cause of the departure of swallows and house-martins as breeding

species. Yet in the autumn of 1896, from September to the middle of

October, hundreds of these birds lived in the central and many other

parks in London, and doubtless they found a sufficiency of food in

spite of the cold east winds which prevailed at that time.

Among the winter visitors to the outskirts of the metropolis, the

fieldfare is the most abundant as well as the most attractive. During

the winters of 1895-6 and 1896-7 I saw them on numberless occasions

at Wimbledon, Richmond, Hampstead Heath, Bostell Woods, Hackney Marsh,

Wanstead, Dulwich, Brockwell Park, Streatham, and other open spaces and

woods round London. In the gardens of the outer suburbs there is always

a great profusion of winter berries, and the felts seen in these places

are probably regular visitors. Certainly they are tamer than fieldfares

are apt to be in the country, but they seldom penetrate far into the

brick-and-mortar wilderness. I have seen a few in Kensington Gardens,

and in November, 1896, a few fieldfares alighted on a tree at the Tower

of London. Stranger still, in February 1897 a flock of wild geese was

observed flying over the Tower: the birds went down the river flying

low, as it was noticed that when they passed over the Tower Bridge they

were not higher than the pinnacles of the two big towers.

[Illustration: FIELDFARES AT THE TOWER]

The birds that are strange to London eyes are very nearly all seen in

the autumn, from September to November. At this mutable season a person

who elects to spend his nights on the roof, with rugs and an umbrella

to keep out cold and wet, may be rewarded by hearing far-off shrill

delicate noises of straggling sandpipers or other shore birds on

passage, or the mysterious cry of the lapwing, 'wailing his way from

cloud to cloud.'

All these rare sights and sounds are for the very patient watchers

and listeners; nevertheless they are the only 'authentic tidings' the

Londoner receives of that great and wonderful wave of life which travels

southward over half the globe in advance of winter. This annual exodus

and sublime flight to distant delectable regions beyond the sea is,

however, only taken part in by some of the feathered people; meanwhile

the others that remain to brave the cold and scarcity are also seen to

be infected with a restless spirit and desire of change. The starling,

missel-thrush, larks and pipits, and other kinds, alter their way of

life, uniting in flocks and becoming wanderers over the face of the

country. Finches, too, go a-gypsying: the more sedentary species leave

their breeding-haunts for suitable winter quarters; and everywhere there

is a great movement, a changing of places, packing and scattering, a

hurrying to and fro all over the land.

The London birds are no exception, although their autumnal movements

have hitherto attracted little attention. These movements are becoming

more noticeable, owing to changes going on in the character of the

metropolitan bird population. The sparrow, as we have seen, does not

leave home, but recently there has been a great increase in the more

vagrant species, the starling and wood-pigeon especially. During the

last few years the wood-pigeon has been growing somewhat more domestic,

and less inclined to leave town than formerly, but from time to time the

old wandering instinct reasserts itself, and it was observed that during

the autumn of 1896 a majority of the birds left London. At Lincoln's Inn

Fields there were thirteen birds down to the end of September, then all

but one disappeared. This solitary stayer-at-home had been sprung upon

and injured by a cat some time before the day of departure.

Last year, 1897, the autumnal exodus was even greater. Thus, on October

25 I walked the whole length of the three central parks, and saw no

pigeons except one pair of young birds not long out of the nest, in Hyde

Park, and one parent bird feeding them. The other parent had probably

gone away to the country, leaving his mate to rear this very late brood

as best she could. Doubtless many of these wanderers from the metropolis

get killed in the country, but in December and January the survivors

return to the safety of the parks, and to a monotonous diet of stale

bread.

It is probable that with the change of temperature in September and

October the London wood-pigeons, like so many birds, are seized by a

restless and roving spirit; but I am inclined to believe that the taste

of wild nuts and fruits, which they get in the parks at that season,

is one cause of their going away. They do not get much of this natural

food; they first strip the oaks of their acorns almost before they are

quite ripe, depriving the London urchins of their little harvest, and

then attack the haws and holly-berries; and when this small supply has

been exhausted the birds go further afield in search of more.

[Illustration: WOOD-PIGEON FEEDING ON HAWS]

On the evening of August 26, 1897, I saw a number of wood-pigeons

feeding on the haws in a manner quite new in my experience. There

were twelve or fourteen birds on a good-sized thorn-tree growing in

Buckingham Palace grounds; but the berries on this tree grew at the

tips of long slender branches and could not have been reached by the

birds in the ordinary way. The pigeons would settle on a branch and

then begin moving cautiously towards the points, the branch bending

beneath the weight more and more until the bird, unable to keep any

longer _on_ the branch, would suddenly turn over and remain hanging head

down, suspended by its clinging feet. In this position, by stretching

its neck it would be able to reach the berries, which it would then

leisurely devour. As many as four or five birds were seen at one time

hanging in this way, appearing with wings half-open like dead or wounded

birds tied by their feet to the branchlets, from which they were

suspended. Since witnessing this curious scene I have been told by Mr.

Coppin, the superintendent at Battersea Park, that he has seen the

wood-pigeons at that place acting in the same way. It is probably a

habit of the birds which has hitherto escaped notice.

* * * * *

The dabchicks leave London in the autumn and return in spring: they may

be looked for in the ornamental waters as early as the third week in

March. The moorhens formerly disappeared from London in winter; they

are now residents throughout the year in a few of the parks where there

is shelter, and during severe frosts they feed at the same table with

the ornamental water-fowl. From all the smaller lakes which they have

recently colonised they vanish in cold weather. In autumn they wander

about a good deal by night; any small piece of water will attract them,

and their cries will be heard during the dark hours; before it is light

they will be gone.

Crows and rooks are most often seen in London during the winter months.

Many rooks have their winter roosting-place in Richmond Park, and small

bands of these birds visit the central parks and other open spaces. On

the morning of February 3, 1897, about fifty rooks visited Kensington

Gardens and fed for some hours on the strip of grassed land adjoining

the palace. The whole jackdaw colony, numbering twenty-four birds, fed

with them, and when, about twelve o'clock, the visitors rose up and

flew away, the daws, after seeing them off, returned in a body to the

tree-tops near the palace, and for the rest of the day continued in an

excited state. From time to time they would rush up with a loud clamour,

then return to the tree-tops, where they would sit close together and

silent as if expecting something, and at intervals of a minute or two a

simultaneous cry would burst from them.

I have observed that on winter evenings these daws fly away from the

gardens in a north-westerly direction: where their winter roosting-place

is I have not discovered.

The starling is the most interesting London bird in his autumn movements.

It is only at the end of July, when they are gathered in large bodies,

that some idea can be formed of their numbers. Flocks of a dozen to

forty or fifty birds may be seen in any park and green space any day

throughout the winter; these are the birds that winter with us, and are

but a small remnant of the entire number that breed in London. At the

end of June the starlings begin to congregate every evening at their

favourite roosting-places. Of these there are several, the most favoured

being the islands in the ornamental water at Regent's Park, the island

in the Serpentine, and at Buckingham Palace grounds and Battersea Park.

The last is the most important. Before sunset the birds are seen pouring

in, flock after flock, from all quarters, until the trees on the island

are black with their thousands, and the noise of their singing and

chattering is so great that a person standing on the edge of the lake

can hardly hear himself speak. These meeting places are evidently

growing in favour, and if the autumn of 1898 shows as great an increase

as those of 1896 and 1897 over previous years, London will have as

compensation for its lost rookeries some very fine clouds of starlings.

At the beginning of October most of the birds go away to spend the

winter in the country, or possibly abroad. In February and March they

begin to reappear in small flocks, and gradually scatter over the whole

area of the metropolis, each pair going back to its old nesting-hole.

The annual scattering of robins at the end of summer, when, after the

moult, the old birds attack and drive away the young, has been described

in the last chapter. This habit of the bird alone would cause a good

deal of moving about of the London robins each year, but it is also a

very general belief of ornithologists that at this season there is a

large migratory movement of young robins throughout the country. At all

events, it is a fact that in August and September robins go about in

London a good deal, and frequently appear in the most unlikely places.

Some of these are no doubt birds of the year hatched in London or the

suburbs, and others may be migrating robins passing through.

At the Tower of London robins occasionally appear in autumn, but soon go

away. The last one that came settled down and was a great favourite with

the people there for about two months, being very friendly, coming to

window-sills for crumbs, and singing every day very beautifully. Then

one day he was seen in the General's garden wildly dashing about, hotly

pursued by seven or eight sparrows, and as he was never seen again it

was conjectured that the sparrows had succeeded in killing him. The

robin is a high-spirited creature, braver than most birds, and a fair

fighter, but against such a gang of feathered murderous ruffians, bent

on his destruction, he would stand no chance.

The Tower sparrows, it may be added, appear to be about the worst

specimens of their class in London. They are always at war with the

pigeons and starlings, and would gladly drive them out if they could.

It is a common thing for some foreign bird to escape from its cage on

board ship and to take refuge in the trees and gardens of the Tower,

but woe to the escaped captive and stranger in a strange land who seeks

safety in such a place! Immediately on his arrival the sparrows are all

up against him, not to 'heave half a brick at him,' since they are not

made that way, but to hunt him from place to place until they have

driven him, weak with fatigue and terror, into a corner where they can

finish him with their bludgeon beaks.

This violence towards strangers of the Tower sparrow is not to be

wondered at, since this unpleasant disposition or habit is common to

many species. The prophet Jeremiah had observed it when he said, 'Mine

heritage is unto me as a speckled bird, the birds round about are

against her.' To the Tower sparrows every feathered stranger is

conspicuously speckled, and they are against her. The wonder is that

they should keep up their perpetual little teasing warfare against the

pigeons and starlings, their neighbours from time immemorial. One would

have imagined that so intelligent and practical a bird as the sparrow,

after vainly trying for several centuries to drive out his fellow

tenants, would have made peace with them and found some more profitable

outlet for his superabundant energies. Possibly the introduction of a

few feathered policemen--owls, or magpies, or sparrow hawks--would have

the effect of making him a less quarrelsome neighbour.

* * * * *

In autumn and in spring a variety of summer visitants, mostly warblers,

pass through London, delaying a little in its green spaces. In September

we are hardly cognisant of these small strangers within our gates, all

but one or two being silent at that season. In April and May, in

many of the parks, we may hear the chiffchaff, willow-wren, blackcap,

sedge-warbler, the whitethroat, occasionally the cuckoo, and a few other

rarer species, but they sing little, and soon leave us to seek better

breeding-sites than the inner parks offer.

While some of our birds, as we have seen, forsake us at the approach of

cold weather, some for a short period, others to remain away until the

following spring, a small contrary movement of birds into London is

going on. These winterers with us come not in battalions and are little

remarked. They are to be found, a few here and a few there, all over

London, wherever there are trees and bushes, but less in the public

parks than in private grounds, cemeteries, and other quiet spots. Thus,

during the last two exceptionally mild winters a few skylarks have lived

contentedly in the comparatively small green area at Lambeth Palace.

Nunhead Cemetery is a favourite winter resort of a number of small

birds--starlings, chaffinches, and greenfinches, and a few of other

species. Chaffinches are found in winter in several of the open spaces

where they do not breed, and among other species to be found wintering

in the quiet green spots in small numbers are linnets, goldfinches,

pipits, and the pied wagtail.

In exceptionally severe winters birds come into London in considerable

numbers--rooks, starlings, larks, blackbirds and thrushes, finches, and

other small species--and they then visit not only the parks but all the

squares and private gardens. During the big frost of 1890-1 skylarks

were seen every day searching for food on the Thames Embankment. These

strangers all vanish from London on the break-up of the frost.

During the late autumn and winter months a few large birds occasionally

appear--heron, mallard, widgeon, teal, &c. As a rule they come and

go during the dark hours. The sight of water and the cries of the

ornamental water-fowl attract them. They are mostly irregular visitors,

and cannot very well be included in the list of London birds.

The case of the black-headed gull is different, as this species may now

be classed with the regular visitors, and not merely to the outlying

spaces, like the fieldfare, but to the central parks of the metropolis,

where, like the wood-pigeon, he looks to man for food.

The black-headed gull has always been a winter visitor in small numbers

to the lower reaches of the Thames, coming up the river as far as London

Bridge. In severe winters more birds come; thus, in the winter of 1887-8

they appeared in great numbers, and ranged as high up as Putney. The

late Mr. Tristram-Valentine, in describing this visitation, wrote:

'It is seldom, indeed, that these birds appeared in such numbers in

the Thames above London Bridge as they have done lately, and their

appearance has, from its rarity, caused a corresponding excitement

among Londoners, as is proved by the numbers of people that have crowded

the bridges and embankments to watch their movements. To a considerable

portion of these, no doubt, the marvellous flight and power of wing of

the gull came as an absolute revelation.'

Gulls came up the river in still greater force during the exceptionally

long and severe frost of 1892-3. That was a memorable season in the

history of the London gulls. Then, for the last time, gulls were shot

on the river between the bridges, and this pastime put a stop to by

the police magistrates, who fined the sportsmen for the offence of

discharging firearms to the public danger. And then for the first time,

so far as I know, the custom of regularly feeding the gulls in London

had its beginning. Every day for a period of three to four weeks

hundreds of working men and boys would take advantage of the free hour

at dinner time to visit the bridges and embankments, and give the scraps

left from their meal to the birds. The sight of this midday crowd

hurrying down to the waterside with welcome in their faces and food in

their hands must have come 'as an absolute revelation' to the gulls.

During the memorable frost of 1894-5 the birds again appeared in immense

numbers, and would doubtless have soon left us, or else perished of cold

and hunger on the snow-covered hummocks of ice which filled the Thames

and gave it so arctic an aspect, but for the quantities of food cast to

them every day. As in previous years when gulls have visited the Thames

in considerable numbers, many of the birds found their way into the

parks, and were especially numerous in St. James's Park, where they

formed the habit of feeding with the ornamental water-fowl.

We have since experienced three exceptionally mild winters, so that the

gulls were not driven by want to invade us; but they have come to us

nevertheless, not having forgotten the generous hospitality London

extended to them in the frost. St. James's Park has now become the

favourite wintering place of a considerable number of birds, and their

habit is to spend the day on the lake, feeding on the broken bread and

scraps of meat thrown to them from the bridge, and leaving about sunset

to spend the night on the river. In the autumn of 1896, three or four

days after the gulls began to appear on the Thames, a body of two or

three hundred of these birds settled down in the park water, and fed

there every day and all day long until the following spring--March 1897.

A favourite pastime of mine during the winter months was to feed these

park gulls with sprats, which were plentiful and could be bought

anywhere for one penny a pound, or in quantities for about a farthing

the pound. Gulls cannot live by bread alone; it is true that even in

London they do not, like the blubber-eating Greenlander, spew it out of

their mouths, for they will eat almost anything, but it is not partaken

of with zest, and even with a crop-full they do not feel that they

have dined. However much bread they had had, no sooner would they see

the silvery gleam of a little tossed-up sprat than there would be a

universal scream of excitement, a rush from all sides, and the whole

white vociferous crowd would be gathered before me, almost brushing my

face with their wings, sweeping round and round, joyfully feasting on

the little fishes, cast to them in showers, to be deftly caught before

they touched the water.

[Illustration: FEEDING THE GULLS IN ST. JAMES'S PARK]

Some of the birds, bolder or more intelligent than their fellows,

would actually take the sprats from the hand.

A very few days before writing this chapter end, on January 30, 1898,

I passed by the water and saw the gulls there, where indeed they have

spent most of the daylight hours since the first week in October. It was

a rough wild morning; the hurrying masses of dark cloud cast a gloom

below that was like twilight; and though there was no mist the trees and

buildings surrounding the park appeared vague and distant. The water,

too, looked strange in its intense blackness, which was not hidden by

the silver-grey light on the surface, for the surface was everywhere

rent and broken by the wind, showing the blackness beneath. Some of the

gulls--about 150 I thought--were on the water together in a close flock,

tailing off to a point, all with their red beaks pointing one way to the

gale. Seeing them thus, sitting high as their manner is, tossed up and

down with the tumbling water, yet every bird keeping his place in the

company, their whiteness and buoyancy in that dark setting was quite

wonderful. It was a picture of black winter and beautiful wild bird life

which would have had a rare attraction even in the desert places of the

earth; in London it could not be witnessed without feelings of surprise

and gratitude.

We see in this punctual return of the gulls, bringing their young with

them, that a new habit has been acquired, a tradition formed, which has

given to London a new and exceedingly beautiful ornament, of more value

than many works of art.
