GENERAL OBSERVATIONS.

Previous

In the year 1872, through the medium of the Natural History columns of “The Field,” a series of observations were made by naturalists in different parts of England on the subject of “Our Summer Migrants.” A form of calendar was distributed and filled up by each according to his opportunities. In this way, by the end of the year six hundred and forty-five separate observations were placed on record, and it devolved upon me to prepare a report from the statistics so furnished. As a good deal of interesting information was thus brought to light, it occurs to me that I may appropriately bring the present volume to a close by extracting so much of the report as relates strictly to the subject matter in hand, and I accordingly do so.

In the calendars returned, some thirty species of summer migratory birds are mentioned with more or less frequency. The majority of the observations upon them have reference, as might be supposed, to the dates of their arrival and departure, or, more correctly speaking, to the dates when they were first heard or seen and last observed. When referring some time previously to the utilization of such observations, it was remarked that upon various points some addition to our knowledge was desirable. Amongst other interesting facts, for example, might be ascertained the precise line of direction in which various species migrate, the causes which necessitate a divergence from this line, the relative proportions in which different species visit us, the causes which influence the abundance or scarcity of a species in particular localities, the result of too great a preponderance of one species over another, whether beneficial or otherwise to man as a cultivator of the soil, the simultaneity or otherwise of departure from this country in autumn, the causes operating to retard such departure, and so forth. All these are matters of interest, especially to those who reside in the country, and have leisure to inquire into the subject. Let us see how far the observations supplied furnish a reply to these inquiries.

Of the thirty species of migrants mentioned, the Swallow, as might be supposed, has attracted the largest share of attention, and in regard to the number of observations made upon it stands at the head of the list with forty-three. The Cuckoo comes next with thirty-eight; the Chiff-chaff and Swift follow with thirty and thirty respectively; and so on through the list, as given below, to the Reed Warbler, upon which bird, strange to say, no more than three observations were made.

The following list will give some idea of the amount of attention which each bird received.

The first Swallow was seen, not as might be supposed in the south or south-east of England, but four miles south of Glasgow, on the 2nd of March, and Mr. Robert Gray states that this is the earliest record of its arrival in Scotland. It is, indeed, an exceptionally early arrival, for nearly a month expired before another was seen at Cromer, on the 31st of the same month, and six weeks elapsed between the first and second appearance of the bird in Scotland. On the 1st April, with a S.E. wind, this harbinger of spring arrived at Great Cotes, in Lincolnshire, and on the 3rd of that month was noticed simultaneously at Nottingham and Taunton. From the 6th of April the arrival of Swallows was pretty general until the 13th, when they were first noticed in Ireland at Ballina, co. Mayo, and on the following day at Glasnevin, Dublin, and at Bray, in the county of Wicklow. The temperature then at Bray was 53°, and the wind S.W. In these localities and dates there is nothing to indicate anything like a precise line of immigration; on the contrary, the birds first appeared where they were least expected. The prevalence of gales, however, at that particular season doubtless operated to retard their progress, and induced them to linger about sheltered localities where food could be obtained. Mr. Wm. Jeffery, who is well situated for observation on the Sussex coast, between the downs and the sea, remarked that most of the spring migrants were several days later than usual in their arrival, and the Swallow in particular not only came later, but lingered longer than is its wont in his neighbourhood. A single bird of this species was seen by him, flying round a steam threshing-machine, on the 10th of December. “Whether it had been disturbed,” he says, “from hybernation in the oatrick which was being threshed, or only attracted by the warmth from the engine, I cannot say. It flew very weakly, and was not long seen.”

On the 2nd of November, with the temperature at 45·5°, and the wind W., the species was still in the neighbourhood of Huddersfield, and on the 13th November, during cold weather, two were seen on the beach at Exmouth. I may here remark that but little attention is paid to the time of departure of a species compared to that which is given to the date of its arrival.

The Martin was observed to come later and go earlier than the Swallow, the earliest and latest dates being respectively April 10 at Marlborough, and November 7 at Leiston, Suffolk. And in the case of this bird the movement northwards might be traced by the dates, as Wiltshire, April 10; Worcester, April 11; Yorkshire, April 11 and 13 (the weather fine, with temperature 53°, and wind W.); Derbyshire, April 15. Further to the westward, viz., at Llandderfel, in Merionethshire, its appearance was not noticed until the 13th of May, when the temperature stood at 48°, and the wind N.W. Strange to say, it was not observed in 1872 by any correspondent in Scotland and Ireland.

The Sandmartin is always amongst the first comers to arrive, and was seen in three different counties during the last week of March, viz., in Sussex, Wilts, and Worcester, the weather dull, with the wind blowing from the westward. Its stay in this country is never so prolonged as that of the Swallow, or even the Martin. Large flights are observed preparing to migrate at the end of August and beginning of September, and at the end of the latter month all have gone southward again for the winter. In 1872, however, the species was seen exceptionally as late as October 7.

The Swift is rarely seen before the first week of May or after the first week of August, and of thirty independent observations upon this bird, three only refer to its appearance during the last days of April, four-and-twenty record its arrival between the 1st and 17th of May, and three only relate to its disappearance—from Garvoch, Perthshire, on July 29, from Leicester on August 2, and from Exeter on August 12. It was first seen upon the Devonshire coast at Plymouth and Torquay, and at the former place was particularly numerous. It may be worth noting that a male Swift shot at Cromer by Mr. J. H. Gurney, jun., on June 15, was found to have the under parts denuded of feathers, which would indicate that the males take their turn at incubation.

The Swallows and Swifts are thus brought together, out of the order of the above list, to admit of a more easy comparison of the dates of arrival and departure. We will now follow the order above indicated, commenting only on such facts as appear noteworthy.

The thirty observations which relate to the Cuckoo tend to show that the usual time of its arrival in this country is between the 20th and 27th of April, and in no instance was it observed before the 6th of April (at Torquay) which was considered an exceptionally early date to meet with it. On the Lincolnshire shore it arrived with a southerly wind, in Merionethshire with a west wind, and on the Irish coast with a south-west wind, the weather warm and mild, the temperature 49° to 50·5°.

The most northerly point of observation was Dundee, where it was seen on April 29, but it had been previously noticed at Garvoch, Perthshire, on the 27th, and near Falkirk in Stirlingshire on the 25th of the same month. In Fife, Forfar, and Tayside, Mr. P. Henderson, from personal observation, has frequently found Cuckoos’ breasts bare of feathers, as if from incubation, and has observed old birds feeding their own young—a fact in the economy of this bird which has frequently been disputed.

As early as the 2nd of March the Chiff-chaff arrived at Torquay; and, being seen at Chudleigh and Taunton on the 9th, at Northrepps, Norfolk, on the 13th, Hovingham, near York, on the 14th, and Melbourne, Derbyshire, on the 28th, it is easy to trace the gradual movement from south to north of this restless but hardy little bird. A south or south-west wind seems to be most favourable to its arrival, but in this case, as in the case of other species, the data are not sufficient to enable one to judge of this with certainty. It was last seen on Sept. 12 at Sparham in Norfolk.

The Willow Wren was noticed in the midland and northern counties long before its arrival was recorded on the south coast. In Devonshire and Sussex it was observed during the first week of April on various dates from the 3rd to the 7th; in Surrey, Berks, Herts, Norfolk, Lincoln, and Yorkshire somewhat later, that is to say, between the 7th and the 10th of the month; and yet at Nottingham and Melbourne in Derbyshire it was seen upon the exceptionally early date of March 29. In every case where the wind was noted at the time, it was blowing from the W. or S.W., generally from the latter quarter.

Only one notice was supplied of its occurrence in Wales, namely, in the parish of Llandderfel on April 28; but this date does not throw much light upon the progress of the bird westward, for its arrival had already been noted at Glasnevin, co. Dublin, on the 10th, and at Ballina, co. Mayo, on the 13th of the same month. On the last-mentioned date its appearance in Scotland was chronicled in the county of Stirling, but no information was given during that year of its having been observed further north.

In the case of the Common Whitethroat something like a line of migration is indicated by the dates at which the bird was observed. Thus, arriving on the Devonshire, Sussex, and Kentish shores on April 11, 13, and 14 respectively, it was in Berkshire, at East and West Woodhay, on the 15th and 16th; in Leicestershire on the 18th, at Nottingham on the 21st, at Great Cotes in Lincolnshire on the 22nd, at Hovingham, near York, on the 23rd, and by May 6 was as far north as Falkirk. The wind, in all cases where it was noticed, was blowing from the west or south-west, the temperature gradually rising from 48° to 62°.

Of the five-and-twenty observations made upon the Blackcap, the majority relate to its appearance in the second week of April, and it would seem that in the case of this species, the further north we go, the later the date of its arrival. At Torquay it was observed on the 7th, Marlborough on the 10th, East and West Woodhay, Berks, on the 15th, Barnsley on the 16th, Burton on the 23rd, and Melbourne, Derbyshire, on the 27th. No record was furnished of its occurrence either in Scotland or in Ireland, where it is at all times a rare bird. It was last seen at Nottingham on Nov. 4. The Blackcap, however, does not invariably quit this country in autumn; many instances of individuals having been seen here in mid-winter have been reported by competent observers. It has occasionally happened, however, that the Coal Titmouse (Parus ater), which is a resident species, has been mistaken for this bird.

In the West of England, during the year referred to, the Redstart seems to have made its appearance somewhat earlier than usual, having been noted at Bishop’s Lydeard, near Taunton, on the 3rd of April. On the 6th it was seen at Keswick, in Norfolk, and on the 8th and three following days in four different localities in Yorkshire; the wind S.W., and the temperature about 51°. After the middle of the month this bird became more numerous, and was very generally observed. In Derbyshire, at Melbourne, it was not seen until April 24, where it seems to have arrived with a S.E. wind; and going still further north, we find it in Stirlingshire and Sutherlandshire on the 27th and 28th. In Ireland it is very rare, and no note was forwarded of its occurrence there in 1872.

The Spotted Flycatcher is always a late comer, seldom appearing before the first or second week in May. Last year, however, it arrived somewhat earlier than usual, and was noticed in Norfolk, at North Runcton, on April 23, and at Barnsley on the 27th; the wind W., and the temperature about 54° with a haze and light rain. Mr. A. D. Campbell states that Flycatchers were unusually numerous at Garvoch, in Perthshire, about the 21st of May, and were first seen there on the 19th. By Aug. 27 they had all disappeared. Only one note was received of its appearance in Ireland—viz., on May 31, at Ballina, co. Mayo. Mr. Thomas Ruddy, of PalÉ Gardens, Llandderfel, Merionethshire, referring to this species, says that he saw the old birds in July catching bees, not only in the air, but on the hive-board.

The Landrail, or Corncrake, as it is indifferently called,[125] arrived pretty generally during the last week of April, and was noticed by a great many observers on the 25th, 26th, 27th, and 28th of that month. On the last-mentioned date it was observed in the county of Dublin, and on May 1st at Ballina, co. Mayo. Apparently it did not reach Scotland until a week later, for the first record of its appearance there is on May 8, at Fife. On May 14 and 15 its presence in Stirlingshire and Sutherlandshire was attested by two good observers. The scarcity of this bird in some seasons is a theme with which readers of “The Field” of late years have become tolerably familiar; but no light is thrown upon the subject, nor is any cause suggested by those from whom calendars were received.

That far-famed songster, the Nightingale, whose notes are so eagerly listened for in early spring, was not heard last year before April 9; but, from causes already referred to, the first utterance of song does not always indicate the earliest arrival, and it is probable that the birds had already been some days in their favourite haunts before their welcome notes betrayed them.

No more favourable locality for this species could be found, perhaps, than that wherein they were soonest observed—namely, the neighbourhood of Ratham, in Sussex. Situated on the flat country between the downs and the sea, about three miles from the former and seven from the latter, with an arm of harbour within two miles, it offers, with its attractions of wood and water, a tempting resting-place to these small winged invaders on their arrival, and furnishes, moreover, a fine post of observation to the inquiring naturalist. Here, throughout April and May, the woods of West Ashling and the copses around Kingley Vale resound with the songs of various warblers, but especially of Nightingales, which find in this safe retreat an immunity from traps which is not everywhere accorded them. On April 10 their remarkable note was detected at Reigate; on the 12th they were singing at East and West Woodhay, in Berkshire; while from the last-named date until April 18 they were daily noticed in various parts of Norfolk and Suffolk. From thence, through Leicester, Derby, and Nottingham, we trace this bird to Yorkshire, where on May 5 we find it at Barnsley, the temperature, according to that good observer Mr. Lister, standing at 50°, and the wind W. Further north than this in 1872 there were no tidings of it, although in former years I have both seen and heard it in the woods by the waterside at Walton Hall, near Wakefield, and have been informed of its occurrence five miles to the northward of York.

I had proposed in these “General Observations” to confine attention strictly to the facts disclosed by “The Field Calendar;” but the subject of the distribution of the Nightingale in England is of such interest to ornithologists, and even to those who, without professing to be naturalists, take a pleasure in listening to the bird, and are not unwilling to learn something about it, that I venture to give an extract from another source which I feel assured will be considered most instructive.

Writing upon this subject in his new edition of Yarrell’s “British Birds,” now in course of publication, Prof. Newton says (vol. i. p. 315): “In England the Nightingale’s western limit seems to be formed by the valley of the Exe, though once, and once only, Montagu, on this point an unerring witness, heard it singing on the 4th of May, 1806, near Kingsbridge in South Devon, and it is said to have been heard at Teignmouth, as well as in the north of the same county at Barnstaple. But even in the east of Devon it is local and rare, as it also is in the north of Somerset, though plentiful in other parts of the latter county. Crossing the Bristol Channel, it is said to be not uncommon at times near Cowbridge in Glamorganshire. Dr. Bree states (‘Zoologist,’ p. 1211) that it is found plentifully on the banks of the Wye near Tintern; and thence there is more or less good evidence of its occurrence in Herefordshire, Salop, Staffordshire, Derbyshire, and in Yorkshire to about five miles north of its chief city, but, as Mr. T. Allis states, not further. Along the line thus sketched out, and immediately to the east and south of it, the appearance of the Nightingale, even if regular, is in most cases rare, and the bird local; but further away from the boundary it occurs yearly with great regularity in every county, and in some places is very numerous. Mr. More states that it is thought to have once bred in Sunderland, and it is said to have been once heard in Westmoreland, and also, in the summer of 1808, near Carlisle; but these assertions must be looked upon with great suspicion, particularly the last, which rests on anonymous authority only. Still more open to doubt are the statements of the Nightingales occurrence in Scotland, such as Mr. Duncan’s (not on his own evidence, be it remarked), published by Macgillivray (“British Birds,’ ii. p. 334), respecting a pair believed to have visited Calder Wood in Mid Lothian in 1826; or Mr. Turnbull’s (‘Birds of East Lothian,’ p. 39) of its being heard near Dalmeny Park in the same county in June, 1839. In Ireland there is no trace of this species.”

It has long been well known that the male birds arrive in this country many days before the females; but, of twenty-three observations made upon the Nightingale, not one refers to or confirms this fact.

The Nightingale has been pictured by poets and naturalists in various romantic situations, but perhaps never before in so unromantic a spot as “under a bathing-machine”! Yet Mr. Monk states that on the 13th of April, 1872, there were “Nightingales on the beach under the bathing-machines along the whole length of the shore at Brighton.” The explanation which suggests itself is that the birds had just arrived, and had sought the first shelter which offered—a woody shelter, it is true, and a shady one, although of a very different kind to that which the birds had been accustomed to.

The observations made upon the Tree Pipit, twenty-one in number, call for no particular comment, save that the direction of the wind at several dates of supposed arrival was from a S.W. or S.E. quarter, corresponding with what has been observed of other migratory birds, and tending to show that they prefer to travel with a side wind rather than with a head wind or the reverse.

In the eastern counties, for example, it was observed that the Tree Pipit arrived in Norfolk with a S.S.E. wind, the temperature being 52°; in Lincolnshire with a wind veering from S. to S.E. and E., the weather dry, cold, and cloudy; in Yorkshire with a S.W. wind, weather fine, and temperature 47·5°. It was first observed at Bushey, in Hertfordshire, as if arriving directly from the eastward, on the 8th of April; and was last heard at Ratham, near the coast of Sussex, on Sept. 15. The furthest point north at which it was noted was near Stirling on May 1. In Ireland it is unknown.

In the case of the Sedge Warbler, we again remark observations on the wind at the presumed dates of arrival in all respects confirmatory of what has been already stated. Four good observers in the counties of Norfolk, Lincoln, Derby, and York noted the direction of the wind when first meeting with this bird as S.S.E., S.W., S.E., and S.S.W., respectively. No record of its occurrence in 1872 either in Scotland or Ireland was received. The general period of its arrival in England seems to be during the last fortnight of April.

About the same period arrives the Yellow Wagtail, or Ray’s Wagtail, as it is called by many, respecting which bird sixteen observations were received from different parts of the country. It does not appear to have been met with further north than Wakefield, and no notice was taken of it by correspondents in Scotland and Ireland.

The Wryneck, or Cuckoo’s-mate, long preceded the Cuckoo in the date of its arrival, having been heard at Reigate as early as March 31, and at Ratham, in Sussex, on April 2. On the 6th and 7th of the latter month it was observed at several localities in Norfolk, and its appearance generally throughout England in 1872 seems to have been noted during the first fortnight of April. Mr. Lister states that, although found in the neighbourhood of Barnsley in previous years, it was not observed there in 1872.

The Nightjar seems to have been generally met with throughout the country as far west as Llandderfel, in Merionethshire, and as far north as Garvoch, in Perthshire. Mr. Gatcombe observed it in the neighbourhood of Plymouth on April 10, but this must be regarded as an exceptionally early date, for the majority of my correspondents did not meet with it until quite the end of April and beginning of May. On the 15th of June Mr. P. Henderson found two young Nightjars on Tents Muir, Fife, amidst a colony of terns (!), and kept them alive for some time on moths, worms, and pieces of raw meat.

The Wheatear and Whinchat received an equal share of attention in the fifteen observations upon each which were forwarded. The first-named appeared at Plymouth as early as March 6, but the observer in this instance, Mr. Gatcombe, states that he hardly ever knew it so early before. It was observed, however, on the same day at Feltwell, Norfolk, by Mr. Upcher; and Mr. Rope reports that in 1871 he saw it at Leiston, in Suffolk, on March 2. In 1872 in the same neighbourhood it did not arrive until March 18, and was much scarcer than in former years. The calendars enable one to trace it that year as far north as Falkirk, where it was seen on April 1; but this is by no means its northern limit, as there is abundant evidence to show.

The Whinchat is not generally seen in this country until the last week of April, and this is confirmed by the notes before me. Mr. J. J. Briggs, however, met with it near Melbourne, in Derbyshire, on April 3; but he appends the remark that he considers this an unusually early date. Mr. J. A. Harvie Browne states that the Whinchat during mild winters occasionally remains in Stirlingshire.

The Lesser Whitethroat was noticed almost exclusively in the midland counties, the earliest date for its arrival being April 12, at Sparham, Norfolk, and the most northerly locality Barnsley. It goes much further north, however, than this, but is considered rare in Scotland, and is unknown in Ireland.

The Grasshopper Warbler was met with throughout the month of April in about a dozen different localities, and, like the last-named species, chiefly in the midland counties. It goes at least as far north, however, as Oban, in Argyleshire. To the westward, it was noted at Taunton in the middle of May. It is a regular summer migrant to Ireland, although in 1872 it was not noticed there by any correspondent.

Like several of the preceding, the Turtle Dove is oftener observed in the southern and midland counties of England, although stragglers are occasionally met with as far north as Northumberland, and even in Scotland. In the Hebrides specimens have been shot in Islay and Skye, but not in the outer islands. Dr. Saxby has recorded several instances of its occurrence in Shetland, and it has twice been procured in Orkney. In Ireland it is regarded as an annual summer visitant to the cultivated districts.

The Wood Wren was noticed nowhere earlier than the 23rd of April, on which date it was heard by Mr. Inchbald at Hovingham, near York; and the paucity of observations on this and the four following species show that they must be very local in their distribution, or less frequently seen than many of their more obtrusive congeners. The Wood Wren apparently comes very much later than either the Chiffchaff or the Willow Wren.

Nine observations only on the Pied Flycatcher were forwarded. These, however, contain one or two notes of interest. The bird has become much commoner of late years, or more observed; and in 1872 it appears to have been met with much further north than usual. A specimen was shot at N. Berwick by Mr. W. Patterson, and exhibited at the Glasgow Natural History Society on the 24th of September, 1872; and another was procured at Biora, in Sutherland, on the 31st of May, by Mr. T. E. Buckley. In Yorkshire it seems to have been very numerous, a score being heard at once in one locality, near York, on the 29th of May. It was found nesting in Norfolk, at Sparham, eggs being laid and the hen bird sitting, on the 3rd of June. To the westward, it was noted at Cirencester; and was found nesting, as in previous years, at Llandderfel, in Merionethshire.

The Red-backed Shrike, or Butcher-bird, is almost confined to the southern midland counties of England, and although stragglers have been met with occasionally in Scotland, it is always regarded as a rare bird there; and in Ireland it is quite unknown. Mr. Cordeaux states that he has never observed it in Lincolnshire. It is always a late comer, seldom, if ever, arriving before the first week in May; and the earliest date recorded for its appearance in any of the calendars is May 2, on which day it was seen at Ratham, near Chichester. Mr. Donald Mathews has observed, in the neighbourhood of Redditch, that it commences nidification immediately on its arrival. The custom which now prevails of “plashing,” or laying the tall hedgerows in which the Butcher-bird delights to dwell, has caused it in many localities to forsake haunts where once it was quite numerous. This has been particularly remarked, in Middlesex and the counties adjoining.

The observations upon the Garden Warbler, of which eight only are furnished, do not call for any particular comment, save an expression of surprise that a bird with so good a song should not have attracted more attention. The 21st of April is the earliest date recorded for its arrival, at Burton-on-Trent. One would certainly have expected also to find more notice taken of the Reed Warbler, a noisy little bird, whose incessant babbling by reedy ponds and at the riverside makes it almost impossible to overlook it. Nevertheless, but three notes were forwarded of its occurrence in 1872—two in Norfolk, at Lynn and Hempstead, and one in Wilts, at Marlborough; at the last-named place on the 31st of May, at least six weeks after its usual time for arriving. It is not easy to account for its being so overlooked, for it cannot be regarded as by any means a rare bird, although it may be a local one.

Colonel Irby, who has had opportunities of seeing many of our summer migratory birds on passage, from two good posts of observation, Gibraltar and Tangier, thus refers to the subject in his recently-published volume on the “Ornithology of the Straits of Gibraltar:”—

“Most of the land birds pass by day, usually crossing the Straits in the morning. The waders are, as a rule, not seen on passage; so it may be concluded they pass by night, although I have occasionally observed Peewits, Golden Plover, Terns and Gulls, passing by day.

“The autumnal or return migration is less conspicuous than the vernal; and whether the passage is performed by night, or whether the birds return by some other route, or whether they pass straight on, not lingering by the way as in spring, is an open question; but during the autumn months passed by me at Gibraltar, I failed to notice the passage as in spring, though more than once during the month of August, which I spent at Gibraltar, myself and others distinctly heard Bee-eaters passing south at night, and so conclude other birds, may do the same.

“The best site for watching the departure of the vernal migration is at Tangier, where just outside the town the well-known plain called the Marshan, a high piece of ground that in England would be called a common, seems to be the starting-point of half the small birds that visit Europe.

“Both the vernal and autumnal migrations are generally executed during an easterly wind, or Levanter. At one time I thought that this was essential to the passage; but it appears not to be the case, as whether it be an east or west wind, if it be the time for migration, birds will pass, though they linger longer on the African coast before starting if the wind be westerly; and all the very large flights of Raptores (Kites, Neophrons, Honey-Buzzards, &c.), which I have seen, passed with a Levanter. After observing the passage for five springs, I am unable to come to any decided opinion; the truth being, that as an east wind is the prevalent one, the idea has been started that migration always takes place during that wind. Nevertheless, it is an undoubted fact, that during the autumnal or southern migration of the Quail in September, they collect in vast numbers on the European side, if there be a west wind, and seem not to be able to pass until it changes to the east; this is so much the case that, if the wind keeps in that quarter during the migration, none hardly are to be seen.

“On some occasions the passage of the larger birds of prey is a most wonderful sight; but of all the remarkable flights of any single species, that of the common Crane has been the most noteworthy that has come under my own observation.

“On the Andalusian side the number of birds seen even by the ordinary traveller appears strikingly large; this being, no doubt, in a great measure caused by the quantity which are, for ten months, at least, out of the year, more or less on migration; that is to say, with the exception of June and July, there is no month in which the passage of birds is not noticeable, June being the only one in which there may be said to be absolutely no migration, as during the month of July Cuckoos and some Bee-eaters return to the south.”
