Chapter 54,261 wordsPublic domain

Paridæ.--Oct. 14th, N.W., windy. Great Titmouse (_Parus major_), some; Blue Titmouse (_P. cæruleus_), a great many passed over in the afternoon of Oct. 10th, N.E., windy; and again a great many on the 11th, under the same conditions. At Great Cotes, Oct. 14th, Great Tit, many; Blue, some; and Coal Titmouse (_Parus ater_), a few. Dec. 9th, _P. major_, several, "second rush." Migratory flocks of the Long-tailed Titmouse (_Acredula rosea_) occurred near Cromer in October.

Motacillidæ.--At Heligoland, Aug. 27th, Blue-headed and White Wagtails (_Motacilla flava_ and _alba_), great many young birds. Sept. 1st, _M. flava_, pretty large numbers with other birds, all restless, passing over; 9th, E., fine. Yellow Wagtail, _Budytes_ (_M. Raii_), great many; 15th, forenoon, _M. flava_, astounding numbers, late in afternoon in great flights overhead, going north to south; 27th, _M. alba_, some. The only migration of Wagtails over Heligoland in August and September, with one exception, appears to have been confined to these two well-known European species--the Blue-headed and White Wagtails of the Continent. The Grey Wagtail (_M. sulphurea_) was first observed at Great Cotes first week in October, and on Norfolk Coast, Sept. 25th.

Tree Pipit, _Anthus trivialis_.--At Heligoland, Aug. 22nd, young birds; 23rd, same; 24th, same, but less numbers; 26th, Meadow Pipit (_A. pratensis_), great many (oftentimes with smart breeze), also many Tree Pipits; 31st, Richard's Pipit (_A. Richardi_), one. Sept. 1st, Tree Pipits, pretty large numbers; 9th, E., fine. Tree and Meadow Pipits, great many, and two _A. Richardi_ seen; 15th, forenoon, Richard's Pipit, some, once seven together, none shot; late in afternoon. Meadow Pipits, great flights. Tree Pipits less; 16th, Tawny Pipit (_A. campestris_), two; 27th, Meadow Pipits, a few. Oct. 6th, Meadow Pipits with Larks in great flights passing overhead. At Coquet L.H., October, 9 a.m., half a score Titlarks. At Spurn, Sept. 6th, migrating with Swallows, but in separate flocks, bents full of Titlarks arriving from sea, came from N.E., wind W. At Leman and Ower L.V., Sept. 13th, Titlarks, numbers on board, fifteen caught. At Swin Middle L.V., Aug. 29th, 6 p.m., two Titlarks and six species of small birds on board, left for W. At Casquets L.H., Aug. 18th, 2 a.m., about fifty struck. Sept. 6th, midnight to 3 a.m., twenty struck. Rock Pipit (_A. obscurus_), Sept. 28th, first seen on Lincolnshire coast; Sept. 22nd, on Norfolk coast.

Shore Lark, _Otocorys alpestris_.--At Heligoland, Oct. 4th, about twenty; 5th and 6th, some; 17th, twenty to forty; 19th, great many; 20th, flights from twenty to one hundred; 21st, great many; 23rd, still larger flights; 26th, a few. Also great numbers in November and up to Dec. 18th; on Nov. 15th, thousands, in flights of hundreds. On the English coast the occurrences of the Shore Lark have been numerous. At Farne Islands, one shot in the autumn. At Scarborough, Mr. Roberts states that since the severe weather in January, 1881, Shore Larks in small flocks have visited the coast, and several have been shot and taken to him. At Spurn, Dec. 12th, flock of thirteen seen. My informant, who is well acquainted with the bird, says, "resting apparently as I was within six yards of them." At Skegness, Lincolnshire coast, last week in October, eight shot. Near Bedford, Oct. 28th, several seen, two shot ('Field,' Nov. 6, 1880). On Norfolk coast a flock at Blakeney, which remained near the place for two months, and others near Yarmouth. At Dover two procured in December.

Sky Lark, _Alauda arvensis_.--The entrances of the migration of the Sky Lark at the East Coast stations are far too numerous to note separately. In many cases they occupy a large portion of the returned schedules, and individually far outnumber any other species. At Heligoland the migration commenced Sept. 25th, already great many overhead; 27th, 9 to 10 p.m., passing. Oct. 5th, morning, great many; 6th, afternoon, great flights overhead; 19th, late in forenoon, great flights passing on; 20th, with Starlings, hundreds of thousands passing overhead and over the sea; 21st, same; 27th considerable passage in the night; 28th, many thousands over the sea; and after this in flights through November and December. On our East Coast they are noticed at thirty-one of the stations making returns, from the Farne Islands to the Casquets, Alderney. At Farne Island L.H., Sept. 30th to Oct. 31st. At Coquet L.H., Dec. 19th. At Teesmouth 5 Buoy L.V., Sept. 25th to Nov. 21st. On Oct. 24th, all day, "great rush." Nov. 21st, "second rush." At Teesmouth, Oct. 6th to 30th. At Whitby L.H., Oct. 14th to Nov. 23rd. At Flamborough in October. At Spurn L.H., Sept. 15th to Jan. 13th. At Spurn L.V., Oct. 6th to 27th--from 9th to 15th every day continuous. At Great Cotes, September, last week, every day and on to Nov. 4th. At Outer Dowsing L.V., Oct. 13th to Dec. 6th; "great rush," Oct. 13th to end of month; "second rush," Nov. 12th. At Inner Dowsing L.V., Oct. 27th to Jan. 4th. At Dudgeon L.V., Oct. 4th to Dec. 15th; "great rush," Oct. 17th and 20th, and night of 27th. At Lynn Well L.V., Oct. 5th to 23rd, on seven days great numbers; 11th, 12th and 13th, continuous during day ("great rush"); after this, from Oct. 23rd to Jan. 3rd, in less numbers. On Jan. 1st, 2nd and 3rd, with Knot; sixteen Larks and fifteen Knots killed against lantern. At Hunstanton L.H., Oct. 8th, great many. At Cromer L.H., Sept. 20th to Jan. 2nd, eleven struck and killed. At Leman and Ower L.V., Sept. 28th to Oct. 27th, on eleven days, day and night; Oct. 23rd, 26th and 27th, "great rush." At Hasbro' L.V., Sept. 1st to Oct. 22nd. At Hasbro' L.H., Sept. 13th to Dec. 27th, thirty killed. At Newarp L.V., Sept. 24th to Oct. 17th. At Cockle L.V., Sept. 27th to Oct. 22nd; Oct. 11th and 22nd, continuous. At Corton L.V., Oct. 7th to Nov. 7th; Oct. 22nd, continuous. At Galloper L.V., Oct. 9th to Nov. 11th, on seventeen days in large flocks, up to five hundred in a flock; Oct. 31st, 11 p.m., half a gale, thirty killed; Nov. 2nd, 10 p.m. to sunrise, about same number, and many on night of 6th, with other birds. At Kentish Knock L.V., only on Oct. 17th. At Shipwash L.V., Sept. 18th, Oct. 4th and 8th, Nov. 22nd; all day, continuous on Oct. 4th. At Swin Middle L.V., Oct. 21st to Jan. 12th. At Tongue L.V., Sept. 27th to Oct. 30th; "rush," Oct. 22nd. On Sept. 27th, hazy, fifty in ship round lantern at 11 p.m.; when stars came out they left. At Goodwin L.V., Sept. 27th to Nov. 7th. At Gull L.V., Oct. 18th to Nov. 2nd. At South-sand Head L.V., Aug. 27th to Nov. 9th. At East Goodwin L.V., Oct. 8th to Jan. 12th. Enormous numbers crossed at these four Goodwin Stations. At Casquets L.H., Oct. 2nd, 11 p.m. to 2 a.m., sixty killed.

The migration of the Lark was carried on all hours of day and night in all weathers from Aug. 27th to Jan. 12th. The "great rush" took place during the last fortnight in October, more crossing probably on the 22nd than any other day, and at Heligoland on 20th and 21st. A "second rush" a month later, on or about Nov. 21st, and a "third rush" on the outbreak of severe weather in the second week in January this year. General line of direction E. to W., sometimes N.E. to S.W., but generally, like the majority of immigrants this season, with a strong trend from points south of east. It is remarkable, as shown by the returns, how frequently Larks are associated in migration with Starlings, either in separate flocks or together; in fact, the two species seem to be inseparable. In a large majority of instances these two meadow-feeders are associated as if impelled to migrate by a common cause.

Wood Lark, _Alauda arborea_.--At Heligoland, Sept. 28th, four.

Snow Bunting, _Plectrophanes nivalis_.--At Heligoland, Sept. 17th, a few first arrivals; Oct. 20th, great many; 20th and 26th, a few; Nov. 20th, still great numbers, but very few old birds. At Farne Inner L.H., Oct. 28th to Dec. 20th; "rush," Nov. 16th, and again Dec. 20th. At Teesmouth 5 Buoy L.V., from Nov. 7th to the end of month, nearly on every day, immense numbers passed; all came from N., and were going S.W. At Flamborough, Oct. 8th, first seen; Jan. 13th, great many flocks. At Spurn L.H., third week in October, a few; 29th, many, after great gale from E. and N.E. At Great Cotes, early in November,--1st to 5th,--many; 24th, enormous flocks. At Yarmouth, middle of October. At Harwich, Oct. 30th, many in Orwell river; Nov. 4th, first flock seen near Dovercourt (Zool., 1881, p. 26). None are recorded from stations south of Harwich. The flocks consisted mainly of the young of the year and old females; very few old male birds. The immigration of Snow Buntings on to the north-easterly coasts in four distinct rushes, _viz._, at the end of October, in November, December, and January, has been attended with corresponding depressions of the barometer and outbursts of Arctic weather, _viz._, the great gale E. to N.E., Oct. 28th, with heavy snow in Scotland; Nov. 18th to 20th, sharp frosts and heavy snow-storms; Dec. 14th and 15th, the same; and Jan. 11th and 12th, same. Mr. Gätke has observed for some years a very marked decrease in the number of Snow Buntings crossing Heligoland. There has been a very great increase in the number arriving on our east coast for the last six or seven winters, and it is probable that, like the Shore Lark and other Arctic birds, the line of migration now runs further to the west than formerly.

Other _Emberizinæ_ occurred as follows:--At Heligoland, Oct. 11th, Ortolan Bunting, _Emberiza hortulana_, many young; 24th, same; Sept. 1st, pretty large numbers; 8th and 9th, many; 15th, great many in potato-lands; 29th, Reed Bunting, _E. schœniclus_, many; Oct. 4th, great many; 6th, same; 8th, great many; 11th, same. Yellow Bunting, _E. citrinella_, 28th, many; and same and Corn Buntings up to Nov. 20th, few old birds. Little Bunting, _E. pusilla_, Sept. 26th, one; 30th, one; Oct. 11th, one. On the east coast of England, at Great Cotes, Sept. 30th, _E. schœniclus_, many. At Spurn, Oct. 26th, a few seen. At South-sand Head L.V., Aug. 29th, four to south.

Chaffinch, _Fringilla cœlebs_.--At Heligoland, Sept. 17th, great many beginning to pass; 25th, enormous numbers passing on high overhead in a westerly direction; 26th, hundreds of thousands high overhead; 27th, some; 28th, thousands so high overhead that they cannot be seen, only their call-notes heard, all day long; Oct. 6th, 7th, and 8th, great many; 11th, same; 27th, still many passing. Great numbers have also arrived on the east coast; they are noticed at fourteen stations, from the Farne Islands to the Goodwins. At Farne Inner L.H., Sept. 1st, 2 a.m., one killed against glass, S.W., misty. At Whitby L.H., Sept. 27th, "Finches," "great rush," with many other species. At Great Cotes, Oct. 13th, very large flocks of females and young of the year about this date. At Dudgeon L.V., Oct. 16th, one male caught on deck; 28th, same; Dec. 5th, one same, going W. At Lynn Well L.V., Oct. 5th and 23rd, many S.E. to N.W.; 25th, in smaller flocks to N.W. At Northrepps, Oct. 13th, Mr. J. H. Gurney saw a huge flock in a stubble-field on the cliff, which he thinks must have come in from the sea. At Leman and Ower L.V., Oct. 19th, 8 to 12 p.m., o.m., six caught on deck. At Newarp L.V., 2 to 3 p.m., Oct. 6th, 14th, and 18th, each day to S.W. At Cockle L.V., Oct. 6th, two on board caught. At Corton L.V., 7 p.m., several males alighted on deck; 15th, 6 p.m., one male caught. At Galloper L.V., Oct. 9th to Nov. 6th, on several days, sometimes with Larks, twelve Larks, nine Chaffinches killed night of Oct. 9th, o.m., heavy rain. At Kentish Knock L.V., Oct. 7th, two at sunrise to S.W.; 15th, two, male and female, caught; 17th, W.S.W., three or four hundred very high to S.W. At Swin Middle L.V. Sept. 18th, sunrise to 10 a.m., Chaffinches with Linnets to W. At Gull L.V., Sept. 28th, 9 to 11 a.m., continuous flocks of Linnets, Starlings, Chaffinches, and Mountain Sparrows to W., many of each on deck. The main immigration of the Chaffinch was from the middle of September to end of October, the bulk of the immigrants crossing south of Yarmouth. The "great rush" on or about Oct. 13th.

Brambling, _Fringilla montifringilla_.--At Heligoland, Sept. 25th, many; 27th, some; Oct. 8th, great many; and on 27th, still more, and also good many throughout November. On the English coast few have been observed. At Flamborough, Jan. 13th, some large flocks. At Leman and Ower L.V., Oct. 6th, one male caught.

Tree Sparrow, _Passer montanus_.--None are recorded as passing Heligoland. On our east coast they were observed at eleven stations, but none are recorded north of Spurn. In North-east Lincolnshire, Oct. 13th, very large flocks were seen about this date. At Dudgeon L.V., Oct. 5th, "Sparrows" to W. At Newarp L.V., Oct. 25th, six going W. by N. At Corton L.V., Oct. 7th, several alighted on ship for a short time, going E. to W. At Kentish Knock L.V., Oct. 9th, seven on board till squall had passed. At Shipwash L.V., Nov. 28th, flocks to N.N.W. At Tongue L.V., Sept. 28th, 11 a.m., o.m., about one hundred Sparrows on masthead; Oct. 24th, twenty to W. at noon. At North Foreland L.H., from October to third week in December, hundreds "mixed" were seen. At Goodwin L.V., Sept. 28th to Nov. 5th, on five days, often with Larks to W. At Gull L.V., Sept. 28th, continuous with other birds from 9 to 11 a.m. to W.; Oct. 16th, from 9 a.m. to 3 p.m., continuous to W. At East Goodwin L.V., Sept. 25th, Oct. 9th, and 11th, flocks flying about ship; 17th, flock from N.W. to S.E.; Jan. 8th, about one hundred from W. to E. towards French coast. From Sept. 25th to Nov. 28th, the majority passing across at the most southern stations the four lightships on the Goodwin Sands. It is possible that some of the entries of "Sparrows," where not distinctly specified, may refer to the Common Sparrow, which is now recognised as a regular immigrant.

House Sparrow, _Passer domesticus_.--At Heligoland, Mr. Gätke says, "Up towards the end of July all young Sparrows disappeared from the island," and "up to middle of September nearly all old Sparrows had also quitted the island." Oct. 10th, "Sparrows latterly influx," from which it appears that the local Sparrows leave, the young first, then the old, and their place is taken by a fresh arrival. At Spurn, last week in Nov., Mr. Hewetson saw an immense flock--hundreds upon hundreds--on the shore, evidently quite fresh arrivals; amongst them was a Reed Bunting. At Outer Dowsing L.V., Sept. 26th, 5 p.m., twenty House Sparrows came on board, travelling from S.E. to N.W.; and on Oct. 2nd, at 4 p.m., eight going E.S.E. to W. At Kentish Knock L.V., Oct. 10th, one Common Sparrow; and on 12th, two, till squall had passed, then to S.W. At Casquets L.H., Alderney, Oct. 13th to 17th, at midnight, Common Sparrows with Thrushes, Blackbirds, Starlings, and Wood Pigeons, to English coast.

Greenfinch, _Coccothraustes chloris_.--At Heligoland, Oct. 27th, many; Nov. 20th, great many. At Corton L.V., Oct. 31st, one, a male, caught.

Goldfinch, _Carduelis elegans_.--At Heligoland, Oct. 27th, some; also through November and December; on Dec. 17th, great many. At Great Cotes, some small flocks in North-east Lincolnshire in October and November, more than have been seen for many years. On Suffolk coast, mouth of Deben, Nov. 1st, seven.

Siskin, _Carduelis spinus_.--At Heligoland, Sept. 16th, a.m., "flights in my garden of (say) fifty; p.m., flights of hundreds"; 17th, "hundreds of thousands"--"flights like clouds"; 25th, many; Oct. 7th, great many; 27th, many still passing; Nov. 4th, W., still some flights. On English coast of Spurn, Oct. 27th, small flock seen. At Northrepps, Sept. 16th, seen by Mr. J. H. Gurney. Have also been reported as more plentiful than usual in other parts of country.

Lesser Redpole, _Linota rufescens_.--In Lincolnshire there were very considerable numbers in our east coast marshes early in October; in one instance, on the 7th, I saw a flock of two hundred in a stubble-field near the coast. At Spurn, Oct. 28th, Mr. Wm. Eagle Clarke saw a flock near Kilnsea.

Linnet, _Linota cannabina_.--At Heligoland, Oct. 4th, great many, first comers; 6th, some; 28th, with Twites, great many. On the English coast, Whitby L.V., Sept. 27th, with many others. At Corton L.V., Oct. 5th, one E. to W. At Swin Middle L.V., Sept. 18th, sunrise to 10 a.m., with Chaffinches to W.; and on previous day, Sept. 17th, all day to N.N.W. with Swallows. At Gull L.V., Sept. 26th to Oct. 25th, on six days with other birds to W. and S.W.; continuous all day on Oct. 24th and 25th. At South-sand Head L.V., Oct. 18th and 21st, Linnets with others all day; 26th, all day with others to W. and N.W. Immense numbers appear to have crossed from Oct. 1st to 26th at the stations off the Essex and Kent coasts; none, or very few only, at stations north of this.

Twite, _Linota flavirostris_.--Is not recorded on the English coast. At Heligoland, Oct. 16th, many passed, first comers; and on 17th, great many; 20th, great many; and on 25th, 26th, and 27th, lesser flights; 28th, many with Linnets.

Bullfinch, _Pyrrhula europæa_.--At Heligoland, Oct. 7th, one, young; 8th, one, young, in garden; 10th, some; 11th, a few; 19th, some; 25th, a few; and through November and December in small parties of ten to twelve; have not been seen on the island for ever so many years. At Spurn, some were seen last week in November; and during the last fortnight in the same month, many in North-east Lincolnshire. Mr. J. H. Gurney, writing from Reigate, Jan. 4th, 1881, says, "There are more Bullfinches in this part of Surrey than I think I ever saw." Extraordinary numbers were seen in Mayo and Sligo, Ireland, in the last autumn and winter (See 'Zoologist,' 1881, p. 133).

Crossbill, _Loxia curvirostra_.--At Heligoland, Oct. 7th, one young bird.

Starling, _Sturnus vulgaris_.--Next to the Lark, this species undoubtedly takes the second rank numerically amongst the migrants. The young birds crossed Heligoland in large numbers from June 15th to July 5th. The old birds beginning to move about Sept. 11th, and from that time to Oct. 27th, enormous numbers passed. On the English coast they are recorded at twenty-five stations, from the Longstone to the Hanois L.H., Guernsey. At Longstone L.H., Nov. 19th, large flocks to W. At Farne Inner L.H., Sept. 30th, to Nov. 13th (Oct. 15th, rush), when they passed all day westward. At Coquet L.H., Oct. 1st and 11th. At Teesmouth 5 Buoy L.V., Nov. 27th, large flocks from S.E. to N.W. At Whitby L.H., July 23rd, one hundred young birds to S. At Flamborough L.H., great numbers in November. At Spurn L.H., Oct. 14th to Nov. 27th, Oct. 23rd and 24th, and Nov. 27th to 30th, all day from N. to S. At Spurn L.V., Oct. 17th, thirty came on board; 27th, Starlings and Larks; two dozen caught going S. At Inner Dowsing L.V., Jan. 4th, one dead on deck at sunrise. At Hunstanton L.H., Oct. 8th, 4 a.m., o.m., rain, E., hundreds with Larks round light, fifteen killed. At Cromer L.H., Jan. 3rd, 1881, 3 a.m., one killed. At Leman and Ower L.V., Sept. 28th and 29th, and Oct. 19th, during night; At Hasboro' L.H., Sept. 13th and 14th, 11 p.m. to midnight, with Larks, twenty stunned, young birds; 27th, midnight, four killed, young; Dec. 27th, midnight, with Larks and Blackbirds. At Newarp L.V., Oct. 13th to 25th, on three days to W. At Corton L.V., Sept. 27th, Oct. 4th, and Nov. 17th, E. to W. At Galloper L.V., Oct. 13th to Nov. 11th, nearly every day large flocks going N.W., day and night, sometimes alone, at others with Larks and small birds. At Kentish Knock L.V., Oct. 8th, 10th, and 13th, to W.S.W., with Larks and many other birds. At Shipwash L.V., Sept. 21st to Nov. 23rd, on several days, sometimes with Larks N. and N.W. At Swin Middle L.V., Aug. 28th, flocks to W. with other birds; and Oct. 30th, to W. with Larks. At South-sand Head L.V., Oct. 10th, continuous with others; also on 17th, 18th, 22nd, and 26th, to W. At East Goodwin L.V., Sept. 24th and 25th, hazy, flocks about ship with Sparrows on 25th; Oct. 16th, hundreds E. to W. At Casquets L.H., Oct. 13th to 17th, midnight, rain. Starlings amongst other birds to N.W. At Hanois L.H., Guernsey, Aug. 14th, night, with many others; Dec. 2nd, midnight, o.m., half a dozen struck. The young migrate first; the old in October and November. Have crossed in the greatest number at the more southern stations, travelling all hours of the day and night in westerly and north-westerly directions; constantly associated with Larks in their migrations. The majority crossed from Oct. 19th to 26th. Again there was a "second rush" near the end of November, and a third the second week in January, before the outbreak of severe weather.

Rose-coloured Starling, _Pastor roseus_.--At Heligoland, Sept. 17th, one, a young bird, occurred.

Grey Crow, _Corvus cornix_.--At Heligoland, Sept. 24th, commencing with flocks of thirty to forty, and passing at intervals to end of October, sometimes in immense numbers; Oct. 7th, towards evening an enormous flight, during night fifty caught by lanterns; and after this passing in smaller numbers to Nov. 2nd. On the English coast they were noticed at seventeen stations, extending from the Farne Islands to the mouth of the Thames. At Farne Inner L.H., Oct. 21st to Nov. 20th, to W. At Teesmouth 5 Buoy L.V., Sept. 10th, two E. to W.; Oct. 12th, great many E.S.E. to W.N.W. At Teesmouth, Sept. 25th, two seen; Oct. 16th and 20th, many. At Whitby L.H., Oct. 24th and 26th, with Blackbirds at daylight. At Flamborough L.H., Oct. 8th, enormous numbers seen. At Spurn, Oct. 12th to Nov. 9th, great many. At Great Cotes, Oct. 9th, 5.30 p.m., gale from N.E., large flock came in, travelling from E. to W., very high. At Lynn Well, L.V., Oct. 10th to 14th, continuous every day from S. to N.W.; again 22nd and 23rd, all day S.E. to N.W. At Hunstanton L.H., Oct. 10th, 11th, and 12th, many E. to W., wind E.N.E. At Northrepps, Oct. 13th, many to N.W. At Leman and Ower L.V., Oct. 21st, 5 p.m., to N.W. At Cockle L.V., Oct. 11th, continuous to W.N.W., and E.N.E. At Corton L.V., Oct. 10th, very high, E. to W., wind E.N.E.; 11th, continuous 9 a.m. to noon. At mouth of Deben, Oct. 29th to Nov. 1st, in numbers. At Galloper L.V., Oct. 24th to Nov. 9th, many flocks. At Shipwash L.V., Oct. 12th, 30th, and Nov. 3rd, flocks N.W. and N.N.W. At Swin Middle L.V., Oct. 22nd, noon to 3 p.m., with Rooks. At South-sand Head L.V., Sept. 16th, ten "Crows" to N.W.--may have been _Corvus corone_; Nov. 4th, two hundred Crows to N.W. The majority of the Hooded Crows arrived from Oct. 8th to 23rd, the greatest number on any given day probably on the 11th. The main body passed on to the east coast between Flamborough and Yarmouth, with northerly and easterly winds, and travelling from E. to W., N.E. to S.W., and S.E. and S. to N.W.

Rook, _Corvus frugilegus_.--Enormous as have been the number of Crows crossing the North Sea the Rook has probably quite equalled them. None were noticed at Heligoland, or indeed at any station north of the Humber; but from Spurn to the Southsand Head they are recorded at sixteen stations, from Oct. 10th to Nov. 12th, the greatest number crossing undoubtedly on Oct. 21st, and the majority during the autumn at the more southern stations. Comparing the immigration of the Grey Crow with the Rook we find that the former crossed more to the north than the latter did. Thus Grey Crows are recorded from the Farnes to the mouth of the Thames: the majority into Holderness, Lincolnshire and Norfolk; the Rooks from Spurn to the South Foreland, the majority into the southern counties. Each, however, came from, and travelled to, the same points of the compass--E. to W., or N.E. to S.W., or S.E. and S. to S.W.
