and leaving that horrible slime which is so unpleasant to the nose of man; and in fact there is hardly a wader or a scratcher (to use Mr. Ruskin’s term)10 that has not at one time or another been taken near Oxford. Sometimes they come on migration, sometimes they are driven by stress of weather. Two Stormy Petrels were caught at Bossom’s barge in the Port Meadow not long ago, and exhibited in Mr. Darbey the birdstuffer’s window. And a well-known Oxford physician has kindly given me an interesting account of his discovery of a Great Northern Diver, swimming disconsolately in a large hole in the ice near King’s Weir, one day during the famous Crimean winter of 1854-5; this splendid bird he shot with a gun borrowed from the inn at Godstow. During the spring and early summer of 1866, our visitors from the sea-coast were constant and numerous. Even the beautiful and graceful little Tern (Sterna Minuta) more than once found his way here; and on the second occasion saved his own life by the confidence which he seemed to repose in man. ‘I intended to shoot it,’ wrote a young friend of mine, ‘but relented when I saw how tame and trustful it was.’
Specimens of almost all such birds are to be seen in the bird-cases of the Museum, and occasionally they may be seen in the flesh in the Market. Both Market and Museum will give plenty to do on a rainy day in winter: —
Ubi jam breviorque dies et mollior aestas
Quae vigilanda viris!
CHAPTER II.
OXFORD: SPRING AND EARLY SUMMER
All the birds mentioned in the last chapter are residents in Oxford, in greater or less numbers according to the season, except the Fieldfares and Redwings, the Grey Wagtail, and the rarer visitors: and of these the Fieldfares and Redwings are the only true winter birds. They come from the north and east in September and October, and depart again in March and April. When we begin our Summer Term not one is to be seen. The berries in the meadow are all eaten up long before Lent Term is over, and though these are not entirely or even chiefly the Redwing’s food, the birds have generally disappeared with them.
They do not however leave the country districts till later. When wild birds like these come into a town, the cause is almost certain to be stress of weather; when the winter’s back is broken, they return to the fields and hedges till the approach of summer calls them northwards. There they assemble together in immense flocks, showing all the restlessness and excitement of the smaller birds that leave us in the autumn; suddenly the whole mass rises and departs like a cloud. Accounts are always forthcoming of the departure of summer migrants, and especially of the Swallows and Martins, and there are few who have not seen these as they collect on the sunny side of the house-roof, or bead the parapet of the Radcliffe building, before they make up their minds to the journey. But few have seen the Fieldfares and Redwings under the same conditions, and I find no account of their migration, or at least of what actually happens when they go, in any book within my reach as I write. But on March 19, 1884, I was lucky enough to see something of their farewell ceremonies. I was walking in some water-meadows adjoining a wood, on the outskirts of which were a number of tall elms and poplars, when I heard an extraordinary noise, loud, harsh, and continuous, and of great volume, proceeding from the direction of these trees, which were at the time nearly half-a-mile distant. I had been hearing the noise for a minute or two without attending to it, and was gradually developing a consciousness that some strange new agricultural instrument, or several of them, were at work somewhere near, when some Fieldfares flew past me to alight on the meadow not far off. Then putting up my glass, I saw that the trees were literally black with birds; and as long as I stayed, they continued there, only retreating a little as I approached, and sending foraging detachments into the meadow, or changing trees in continual fits of restlessness. The noise they made was like the deep organ-sounds of sea-birds in the breeding-time, but harsher and less serious. I would willingly have stayed to see them depart, but not knowing when that might be, I was obliged to go home: and the next day when I went to look for them, only a few were left.
These birds do not leave us as a rule before the first summer visitors have arrived. In the case I have just mentioned, the spring was a warm one, and the very next day I saw the ever-welcome Chiff-chaff, which is the earliest to come and the latest to go, of all the delicate warblers which come to find a summer’s shelter in our abundant trees and herbage.
I use this word ‘warbler’ in a sense which calls for a word of explanation: for not only are the birds which are called in the natural history books by this name often very difficult to distinguish, but the word itself has been constantly used to denote a certain class of birds, without any precise explanation of the species meant to be included in it. Nor is it in itself a very exact word; some of the birds which are habitually called warblers do not warble in the proper sense of the word,11 and many others who really warble, such as the common Hedge-sparrow, have no near relationship to the class I am speaking of. But as it is a term in use, and a word that pleases, I will retain it in this chapter, with an explanation which may at the same time help some beginner in dealing with a difficult group of birds.
If the reader of this book who really cares to understand the differences of the bird-life which abounds around us, will buy for a shilling Mr. Dresser’s most useful List of European Birds,12 he will find, under the great family of the Turdidae, three sub-families following each other on pages 7, 8, and 9, respectively called Sylvianae, or birds of woodland habits, Phylloscopinae, or leaf-searching birds, and Acrocephalinae, or birds belonging to a group many of the members of which have the front of the head narrow and depressed: and under all these three sub-families he will find several species bearing in popular English the name of warbler. At the same time he will find other birds in these sub-families, which are quite familiar to him, but not as ‘warblers’ in any technical sense of the word; thus the Robin will be found in the first sub-family, and the Golden-crested Wren in the second. But, leaving out these two species, and also the Nightingale, which is a bird of somewhat peculiar structure and habits, he will find four birds in the first sub-family belonging to the genus Sylvia, which are all loosely called warblers, and will be mentioned in this chapter as summer visitors to Oxford, viz. the Whitethroat (or Whitethroat-warbler), the Lesser Whitethroat, the Blackcap, and the Garden-warbler; he will also find two in the second, belonging to the genus Phylloscopus, the Chiff-chaff and the Willow-wren (or Willow-warbler), and two in the third, belonging to the genus Acrocephalus, the Sedge-warbler and the Reed-warbler. Let it be observed that each of these three genera, Sylvia, Phylloscopus, and Acrocephalus, is the representative genus of the sub-family in this classification, and has given it its name; so that we might expect to find some decided differences of appearance or habit between the members of these genera respectively. And this is precisely what is the case, as any one may prove for himself by a day or two’s careful observation.
The birds I have mentioned as belonging to the first genus, i. e. Whitethroat, etc., are all of a fairly substantial build, fond of perching, singing a varied and warbling song (with the exception of the Lesser Whitethroat, of whose song I shall speak presently), and all preferring to build their cup-shaped nest a little way from the ground, in a thick bush, hedge, or patch of thick-growing plants, such as nettles. They also have the peculiarity of loving small fruits and berries as food, and are all apt to come into our gardens in search of them, where they do quite as much good as harm by a large consumption of insects and caterpillars.
Secondly, the two kinds of birds belonging to the genus Phylloscopus, Chiff-chaff and Willow-warbler, are alike in having slender, delicate frames, with a slight bend forward as of creatures given to climbing up and down, in an almost entire absence of the steady perching habit, in building nests upon the ground with a hole at the side, and partly arched over by a roof of dried grass, in feeding almost exclusively on insects, and in singing a song which is always the same, each new effort being undistinguishable from the last. In fact these two birds are so much alike in every respect but their voices (which though unvarying are very different from each other), that it is almost impossible for a novice to distinguish them unless he hears them.
Thirdly, the two species belonging to the genus Acrocephalus, the Sedge- and Reed-warblers, differ from
