Report on the Migration of Birds in the Spring and Autumn of 1884. Sixth Report (Vol. II No. 1)

Part 9

Chapter 94,051 wordsPublic domain

Mr. William Irvine sends two interesting schedules from Barra Head. In September a continuous flight of birds flying east is noticed on 6th, light S.E. wind.

From Rona Lighthouse the Goldcrest, a single bird, is recorded in October as unusual, and is accurately described; evidently of rare occurrence here.

I have to thank Mr. McCulloch, Kyleakin, for the careful attention he has given to the subject of direction of flight in every instance of a record, and, I may add, I am pleased to find much more attention paid throughout the 1884 records to this important item of our inquiries.

_Skerryvore._--Mr. Thomas Dawson sends full schedules from February to December, but remarks, "Not one bird seen here between Dec. 1st and Jan. 15th, date of latest schedule." The only evidence of rushes was that of _Turdidæ_, in November, correlating with E. coast rushes, but there are many light entries. The same gale which detained a Blackbird on the rock also detained Mr. Crow, the under light-keeper, twelve days after time at Hynish Signal Tower. He and the Blackbird changed residence on the same date.

_Dhuheartach._--Numerous light entries also from this station, dating Dec. 2nd, by Mr. William Davidson.

_Sound of Mull._--Mr. William McLellan pays careful attention to the directions of flight, and set of the tides and movements of birds in connection therewith.

_Rhuvaal._--Mr. George Boreham also notes these important particulars, and takes note of the rainfall in August--3rd to 25th--a new feature in our reports. He adds, "It is only very rarely a bird strikes our lantern, as they keep well off shore when passing on the wing."

_M'Arthur's Head._--Evidences of a rush of migrants, of many species, are given in Oct. 7th, 8th, 9th, by Mr. W. Mail. Wind prevailing S.W., but an E. gale on 9th, when "great numbers" are recorded.

_Skervuile._--Mr. John Ewing sends well-filled schedules dating Jan. 13th to Nov. 19th, giving many directions of flight. A curious and interesting note is added. "On Oct. 5th" a "Sandpiper" occurs. "This bird came to the rock five years ago, when I succeeded in taming it, but I have not seen it since that time till now."

_Rhinns of Islay._--Mr. Peter Anderson makes a very good proposal indeed, and that is that our Committee ask the cooperation of assistants as well as principals, as "by so doing you will have a far better chance to get more notes; because, as at present assistants care very little about recording their operations, as they get no credit for doing so, whilst they have one-half of the night on duty." Mr. Anderson anxiously desires a "small book of plates of birds," and complains of the confusion connected with local names in different parts. I have urged, and still urge, on our Committee the advantage there would be in a printed list of local names. For Scotland, the MS. is ready in my hands to be made useful as it stands, and there is abundant room for enlargement; but it would cost somewhat to print and distribute it. I have three excellent schedules from Mr. Anderson. I think his proposals are worthy of the attention both of our Committee and of the British Association. Mr. Ross has also materially assisted Mr. Anderson in filling these up. We would be glad to receive from all stations the names of _all the assistant keepers_, which can be inserted in next return of schedules. A very pronounced rush is recorded at this station. It is quite a principal station on our W. coast.

_Lamlash, Arran._--Mr. David M. Scott does not consider it necessary to mention all occurrences of Herons at this station, "as they breed on the high rocks on the Island, and, of course, are always in the locality."

_Turnberry._--From February to December almost all records are accompanied by winds from S.S.E., S. or E. We have records on twenty-one dates in that time, and only on one day (Nov. 19th) is the wind out of another quarter, _viz._ N.N.W.; on this date a solitary Redshank was killed at the lantern.

_Corsewall._--Rushes evident both in spring and autumn. Winds on dates of heaviest records S. to E. and N.E., but also heavy returns on Sept. 22nd, with fresh S.W. and haze. Dates of rushes very marked. A short but largely bulking schedule.

_Mull of Galloway._--The migration is, on the whole, more distinctly shown in October on the West Coast south of the Clyde than on the East Coast at Isle of May during October. The direction of flight usually given is, where noticed, S.E. While on the East Coast, at Isle of May, winds were north of either E. or W. between Sept. 26th and Oct. 17th, on the West Coast south of Clyde they were S. and W. light. The coast lines in the W. thus showed their influence on the migration; and the normal winds, being west on the West Coast, developed a larger and steadier visible migration than on the East Coast. The only Woodcock recorded at this station in October--Oct. 19th--came during strong N. breeze. A considerable number of Swallows occurred between June 29th and July 4th, when there was a rush. I have no returns from the Mull of Galloway after Oct. 23rd.

_Little Ross._--Considerable evidence of rushes in latter end of October and in November. Mr. James Ferrier says, "Since the above dates--_viz._, plates of last schedule, 18th Nov. to 24th Dec.--there have been no birds." ... "No day migration observed here."

_Langness, Isle of Man._--Mr. Robt. Clyne, formerly under-keeper at Isle of May, writes that he considers the great flights of Linnets--grey and green--are all local, and also Starlings, and he thinks they need hardly be mentioned in the schedules, in the meantime. A very large congregation of Green Linnets took place at Langness on Nov. 19th, which must be noticed in connection with our records elsewhere, on both E. and W. coasts (J. A. H. B.),--probably about 500 to 600, Mr. Clyne says. The Committee marvels very much what can have become of their late coadjutor Mr. Philip M. Kermode. He has not, to Mr. Clyne's knowledge, as yet paid him a visit. Mr. Clyne mentions the abundance of Red-legged Crows. He had entered them as "Jackdaws," but subsequently has become aware of the error. They are numerous about Castletown. Very little fog has been experienced, and the fog-signal has only been once used in the past two months (_in lit._ Nov. 24th). The Committee are much obliged to Mr. Clyne for his interesting and well-filled schedules. He gave some interesting notes also on the species breeding around the station.

_Chickens Rock, Isle of Man._--A very heavy rush is recorded between 15th Oct. and 21st to 26th, "the flocks being so dense that no approximate number could be given; they formed by far the most numerous flocks of migrants seen this season" (James Black, principal keeper). We were singularly unfortunate at the Isle of May, the winds there being N. of E. or W.; while here, in the Isle of Man, they were, during the heaviest filled dates, 15th and 21st Nov., strong W. and haze, the migrants crossing the wind, and showing largely at these more southerly stations of our West Coast.

To Mr. M'Iver, Teacher at Culken, in Assynt, Sutherland, I am obliged for some land notes of interest, which will appear under the various species in connection with Stoir Head Lighthouse.

Report under Species.

Turdidæ.--While in 1883, Spring migration almost escaped notice on the West Coast, in 1884 a rush was very evident between the 18th and 20th Feb., at stations south of Clyde, such as at Corsewall, and indications of same movement north of Clyde, at Skerryvore; but most records south of Clyde. Doubtless Isle of Man could also testify to this, but we have no schedules thence till date of July 20th, when Mr. Clyne went there. There are also a few movements in March at Skerryvore and Skervuile. In both months winds light S.S.E. or S.E. In autumn, much greater than on the East coast. Every station from Cape Rhu Stoir, south, gave movements, as follows:--Rhu Stoir (slight), Barra Head (six seen, 19th Nov.), Rona (light, and only in July), Kyleakin (light indication, 15th Nov.), Skerryvore (a number, 12th, 15th and 16th Nov.), Dhuheartach (light, 15th, 16th to 24th Oct., a few as early as 4th July and 1st Aug., probably local), Sound of Mull (few only, on 19th Sept. and 19th Dec.), Skervuile (light, in November), Rhinns of Islay (enormous rush of Redwings, Thrushes, Fieldfares, Blackbirds, with Woodcocks, Larks, Crows, 14th to 19th Nov.), and southwards, at Lamlash, Arran (good indication on 10th), at Corsewall (a rush on 10th), at Mull of Galloway (rushes, between 10th and 13th and 23rd), and at Little Ross (mostly of Blackbirds). Winds, north of Clyde, in October northerly and westerly, and in November southerly and easterly; for the most part returns lighter in October than in November, and great rushes in November at stations south of Clyde, where winds, during latter half of October and November, were S. and easterly. Great rushes all this time, correlating with East Coast of England, but not so much observed on East Coast of Scotland, owing to winds then being N., and never S., of E. or W. The species mentioned are for the most part Thrushes and Blackbirds, Fieldfares and Red-wings, but there is reason to believe that the latter really bulk largely in the migration, as where the bird is distinguished from the Thrush or Mavis they appear to have come in numbers,, as at Isle of Man (R. Clyne) and Rhinns of Islay (Peter Anderson and Wm. Ross). The migration extended over a considerable time; yet the rushes were remarkable for intensity and uniformity in time at the various stations. The earliest record given is at Dhuheartach (July 4th), but may have been a local movement, along with two other summer records. Next in August (1st, 10th and 28th, a few). Actual first migration in mass commencing Sept. 19th, 21st, and 25th at Sound of Mull, M'Arthur's Head, and Corsewall, respectively. The latest records reaching me date Dec. 19th, at Sound of Mull,--a solitary Blackbird; and by the 19th Nov. the body of the rush was past, the latest record being on that date at Rhinns of Islay. The rush was strictly defined, and there are not many full records before the last week in October. The earliest species recorded (excluding July) is Thrush, and the next Fieldfares, at Skervuile. The latest species recorded are Blackbirds, at Sound of Mull. Those species which bulk largest are Blackbirds and Thrushes; and those least, Fieldfares. Redwings are probably more numerous than actually recorded, as all our reporters do not perhaps distinguish them.

Saxicolinæ.--_Note._--For all purposes of this Report, "Stonechats" and Wheatears are identical. Where true Stonechats are recognised and mentioned, the records relating to these are kept distinct. In Spring: earliest Wheatears at Sound of Mull (29th March); latest, single bird at Skerryvore, 14th May, and one on 11th; appearance of rush at Skerryvore on 22nd, twelve birds at the lantern, fresh S., haze; and at Skervuile indications on 22nd to 24th, light E. and S.E. In Autumn: earliest at Isle of Man stations, 2nd, 9th, and 10th Aug.; almost a rush on 10th at Chickens Rock; and several, 9th and 10th, at Langness. [_Note._--Chickens Rock reporter calls them "Stonechats," but Langness reporter correctly terms them "Wheatears."] Then at Rhu Stoir, in the north, comes the next earliest date, 16th Aug. Thereafter stations returning them are Rhu Stoir, Skerryvore, Dhuheartach, Skervuile, Chickens Rock, and Langness. Bush appears most decided at the early dates at Isle of Man; and again between 20th and 24th Aug. at Dhuheartach, N. of Clyde, and at Skervuile; whilst a third considerable movement is noticeable on 15th and 26th Sept., at Isle of Man. The latter is also the latest date on record. Besides Wheatears we have the following records of true Stonechats (Stonechat, Pratincola rubicola). Earliest at Dhuheartach, August; and at Skervuile between 20th and 26th, accompanying rush of the last species. Of Redstarts only one record; and two or three at Langness on 8th Sept. Winds in August at most localities, S., S.E. and S.W., light or fresh.

Silviinæ.--In spring only one record, _viz._, Robin; one, at Monach Isles, on 7th April, S.E., clear; and a rush at Corsewall on 29th March. In autumn: earliest at Kyleakin, 24th Aug., light S. (Two previous records on 19th and 28th July at Rona, Skye, are in the debatable ground between local and general migration.) In September two single records only, at Sound of Mull and M'Arthur's Head, both on 19th, at which latter station it is reported as "arriving in winter." One Blackcap, female, sent me for identification from Skerryvore, on 16th Nov., moderate N.E., haze, completes our records of this group.

Phylloscopinæ, Gold-crested Wren.--Evident rush noticeable in spring, when great numbers, along with the Robins, were seen at Corsewall on 29th March. One bird occurred at Monach Isles, "new to Mr. Youngclause," but accurately described, therefore hitherto rare at that station; and one is recorded from Rona Skye, but no date given. In autumn a considerable migration, beginning with the earliest at Sound of Mull, on 28th Aug., strong S., with showers. Ending with latest at Lamlash, on 16th Nov., a single bird. (Note here the exactness of how even single records on West coast agree with movements on the East coast.) Scattered records occur at Lamlash, Firth of Clyde, and at Corsewall, between 10th and 19th Sept.; almost a rush on latter dates. Rush on 24th at Little Ross, and indications of ditto at Langness, on 17th and 18th; desultory records at Little Ross before these dates, 11th to 22nd. In October evidence of rushes on night of the total eclipse of the moon, _viz._, 4th Oct., between the same hours, 9 and 12 midnight, the hours of total eclipse of greatest darkness, just as was observed by Mr. Geo. E. Paterson and myself at Isle of May, on the East coast; another indication of a rush, between Oct. 19th and 23rd, at Mull of Galloway. Only single records at Dhuheartach, Skervuile, and Lamlash in November; but, as before remarked, these single records marvellously coincide with East Coast records, and are therefore important. Wind at stations returning, mostly light and various, W., E., and S. Night of eclipse, light W., cloudy and dark. Of Willow Warblers, a few on 10th and 11th Sept., at Little Ross.

Acrocephalinæ.--No records either spring or autumn. The negative evidence is worth positive record.

Paridæ.--Two records only. At Mull, of Galloway, on Sept. 10th, two Titmice, in strong S. wind at lantern, and at Sound of Mull, two struck, but not killed, on Oct. 30th, light S.W. How far these are only local movements or not, it is difficult to know with the small data yet to hand.

Troglodytidæ.--On March 30th, one Common Wren returned in schedule from Monach Isles. Fresh south haze. It would be interesting to know the original starting place of this solitary Wren. The newly-discovered insular variety of St. Kilda is, however, probably entirely resident there all winter. Nevertheless we would like specimens of Wrens from Monach Isles at all seasons for examination. In September, one occurred at Lismore, sitting on rock, on 22nd, light N.E. wind and haze. In October a single bird at Rhu Stoir, at noon, strong S. and rain, and three occurred at Lamlash on Nov. 4th, flying south against a strong S.W. wind and showers.

Motacillidæ.--Only spring record of Wagtails on May 11th two males and two females at Rhu Stoir. In autumn, earliest Aug. 27th, at Skerryvore, when one remained three days on the rock, indicating thus the correlating rush on 31st at Langness, where about a hundred in a large flock of young Pied Wagtails were seen all day. These are called "Grey Wagtails or young Pied Wagtails" by Mr. Clyne. The true Grey Wagtail is a yellow bird with a black throat and very long tail. [Surely British ornithologists can find a more descriptive and truer name than Grey Wagtail for _Motacilla boarula_. If confusion occurs amongst ordinary observers as to names, it is as often the fault of the naturalists who misapplied the names in the first instance as not.] In September a further rush of the same young Pied Wagtails observable on the 10th at Langness--a flock seen--and a dozen at Rhinns of Islay on 7th; and a few at Barra Head and one at Dhuheartach on Sept. 1st. In October a few at Langness, on the 6th, the latest given.

Motacillidæ, Pipits.--Earliest Meadow Pipit in spring, single records on 8th and 21st, at Skerryvore, light S.E. haze and fresh N.W. clear respectively. One rested on lantern of Lamlash Light on May 2nd. In autumn, the rush of Meadow Pipits took place at Isle of Man--Langness during Sept. 4th (a lot), 9th (very many), 24th (large flock), 29th (large flock). Earliest, August 31st (large flock). Later, a few in October at Skerryvore, on 6th and 16th, fresh S.W. breeze, and at same station on 1st and 12th Nov., fresh S.W., rain.

Muscicapidæ, Flycatchers.--Only one record at Longness (R. Clyne), the first record in six years' observation, on Sept. 11th. Mr. Clyne has met with the Pied Flycatcher on Isle of May, as well as the Spotted, but these two seen on Isle of Man are only designated "Flycatchers." As the Pied Flycatcher breeds in Cumberland and N. of England, it would be interesting to know which species (or if both) visits Isle of Man.

Hirundinidæ, Swallows.--Dates of arrivals are as follows:--March 30th, at Corsewall. It is worthy of note that I observed a Swallow at Glendoune Girvan hawking for insects as late in autumn of 1884 as Nov. 8th (see East Coast Report). May 11th, three seen at Rhu Stoir (an early arrival for Sutherland W. coast, J. A. H. B.), light south, one seen at Skerryvore, light S.E.; 17th, one at Skerryvore, fresh, S.W.; 14th, three at Lamlash; 19th, several all day at Rhinns of Islay, light S.E., haze; 21st, one seen at Rhu Stoir, light S.; 22nd, two Sand Martins at Barra Head; June 3rd and 4th, two Sand Martins at Barra Head, light N., cloudy; 19th, two Swallows at Kyleakin, flying S., light S. and clear; 22nd, one Swallow at Rhu Stoir, light fog and rain; 29th, great numbers (rush) flying around at Mull of Galloway, and ditto flying E. at same place on 30th; and on 30th one seen at Cape Wrath; in July, eight Swallows on 3rd and "scores" on 4th (probably local at Mull of Galloway, preparing for departure); one at Langness on. 25th; in August, flock at Langness of Swallows on 20th, and another on 25th; in September, several on 5th, at Langness, and on 8th and 10th, and single records at same place, and at Rhinns of Islay on 29th and 30th; in October, a large flock of Swallows and a party of twelve at Langness, and a flock at Chickens Rock on 6th; a flock of twelve on 19th at Langness, the latest record.

Fringillidæ.--Very few returns in spring. A few Grey Linnets on May 12th at Skervuile, and a few at Rona, Skye, on 26th, being all. In autumn, a rush, and earliest record save one, at Rhuvaal, of young Grey Linnets flying W. on Aug. 20th, and a few same day at Skervuile. The earliest date is a flock at Isle of Man (Langness) on July 29th. Latest record on Nov. 19th of Green Linnets, a rush of 700 or 800, and rushes between 4th and 19th, all at Langness. Bushes during latter end of October at Langness, and sufficient indications at several stations N. of Clyde, as Kyleakin, Skervuile, and Rhinns of Islay. This species bulks largest in all the schedules. Other species noticed are Sparrows (large flock at Langness, Oct. 13th); "Mountain Sparrow" (true Tree Sparrow), one at Rhinns of Islay; "Small Linnets" (Twites or Redpoles?) at Rhinns of Islay, Oct. 21st; Chaffinch, a few stray entries at Dhuheartach, one found dead on rock on Nov. 2nd, others seen on 17th and 19th (male), and a flock at Langness on Oct. 3rd.

Emberizidæ, Buntings.--Snow Buntings in spring, 203 on 14th to 17th March at Barra Head; a large flock at Rhu Stoir on 16th, and one female, same place, on 24th; flock at Monach Isles April 4th; one female at Rhu Stoir as late as June 2nd, fresh various rain. In autumn, records light everywhere. One in October only at Barra Head; ten on Nov. 2nd at Cape Wrath; ten on 7th at Barra Head; odd birds at Skerryvore and Dhuheartach on 16th, and an apparent rush or local flight of fifty on Island at Rhinns of Islay on 14th, and a number (with Thrushes) on 16th at same place.

Alaudidæ, Larks.--Autumn migration of 1883-4 continued with some force into January, 1884, especially noted at Kyleakin, or these may have been local flights. In spring, Larks occur sparingly at same time as Thrushes and Starlings. Feb. 1st, at Lamlash, and Feb. 19th at Skerryvore; also nine (three killed) at latter station March 10th; no more till June 15th; "Larks" at Skervuile, and four on 29th at Dhuheartach. In July, four at Dhuheartach. In autumn, earliest record at Dhuheartach on Aug. 1st, the only record that month; then only a single bird all September, on 21st, at Langness. Latest record, October 24th, a few at Rhinns of Islay. The rush was very great, and took place between the 14th and 21st October, or perhaps more compressed still between the 14th and 19th Oct. The whole duration of time in which Larks migrated is thus very limited this season, _viz._, between Oct. 14th and Oct. 24th, the latest date given. During the rush, which was observable principally at Rhinns of Islay, north of Clyde, the wind was northerly or north-westerly, the same as on the East Coast at the same dates, which accounts for the body of the rush penetrating more to the north and reaching further than in other winds. At Rhinns of Islay hundreds, and on 19th thousands were seen, wind fresh W. to N.W. All flying west. On the East Coast the winds favourable to their continued flight prevented my observing them in any great numbers at Isle of May, but there can scarcely be any doubt these great flights passed up the Firth of Forth, as we had plentiful opportunities of seeing almost continuous indications of their presence at the above dates on the Isle of May. The stations returning Larks are Skerryvore, Dhuheartach, and Rhinns of Islay, and Langness (only a small record on Oct. 2nd). Query, will our Irish Coast returns show the continuance of this flight of Larks?

Sturninæ, Starlings.--Spring, rare indications at Rhu Stoir, March 25th (probably local), one female, and at Lamlash, one on April 1st, and March 2nd one killed, and at Corsewall on Feb. 19th, struck along with Thrushes and Larks. The latter record may have been an indication of real migration, the others are most likely local only. In autumn, earliest Aug. 12th, at Isle of Man, a flock; on 23rd, a number at Rhinns of Islay, culminating in hundreds and hundreds on August 30th at Langness (Isle of Man), and again in hundreds and hundreds at Langness Sept. 18th, and indication by a flock at Mull of Galloway. Again, in October, rushes evident it may be said between 18th and 23rd, and on 29th, observable at Kyleakin (on 18th), at Mull of Galloway on 22nd and 23rd, "flocks," and on 29th by 200 or 300 at Rhinns of Islay. Another rush along with Thrushes, &c., dating Nov. 14th, at Rhinns of Islay. Indications of movements also at Kyleakin and Dhuheartach on Nov. 1st and 2nd. Latest, a solitary record on Dec. 24th at Lamlash. Migration of this species we may designate in 1884 as short, sharp and decisive.
