BAXTER and LEONORA JEFFREY RINTOUL. WE again visited the Isle of May this autumn and worked there from the 2nd September till the iSth October. During this time we were able to record 99 species, three of which were new to Forth, and after we left two other Forth novelties were sent off to us. With its usual sweet reasonableness the wind, after having been in the east almost all summer, veered round and blew off the west for all but the last few days of our visit. Occasionally there were easterly airs below, but the upper currents were still off the weather was fine and mild. the west ; throughout very These conditions militated against rushes of migrants, and it was not till the last few days of our stay, when an honest east wind set in, that any great numbers of birds appeared. It being impossible, in the space at our disposal, to enter into detailed accounts of the movements of each species, we pro- pose to deal briefly with some of our more outstanding records. the Missel Thrushes Among Turdinas, ( Turdus viscivorus) appeared more plentifully than in other seasons, though never in any great numbers, and there were Song Thrushes 1 island (Turdus philoinelos } on the almost every day. 1 " The nomenclature adopted is mainly that of Dr. Hartert's Die Vogel der palaarktischen Fauna." 77 B r\ 2 ANNALS OF SCOTTISH NATURAL HISTORY Rushes of this species occurred on iith, i6th, 25th, and 3<Dth September, and ist, /th, and loth October, and a very one on the I ith we pronounced ; procured Thrushes out of each rush, but they all proved to be of the British racial form T. philomelos darkei. It may be worth recording here, that among the SongThrushes procured in the autumn of 1 909 on the Isle of May, there were several belonging to the foreign race T. The first philomelos philomelos. Redwing ( Turdus musicus} appeared on 2 7th September, on /th October a good many arrived, from the I2th to the i$th there were numbers present, and on i6th October (S.E. wind, very light, hazy) a great rush occurred. The birds came in from the north during the whole day, most plentifully in the morning, and in addition to those that alighted on the island, we saw and heard countless numbers passing overhead. A Fieldfare (Turdus pilaris) was seen on 25th September, an unusually date saw no till I ith after early ; we more October, which they occurred daily. From I4th to i/th October, with an easterly wind, great rushes of Blackbirds (Turdus merula) took place, the dome of the lighthouse being thronged with them in the early mornings, and the island covered with them almost all were males with black bills. ; young No Thrushes arrived during these Blackbird rushes. Ring Ouzels (Turdus torquatus) occurred in small numbers between 25th September and i/th October. One of the features of this season was the number of Greater Wheatears {Saxicola cenantlie occurred almost from 6th leucorJwd] ; they daily September till 1 2th October, and we noted that they very often arrived during the day, usually about 4 p.m. These birds were very fond of hiding under stones, and would often crouch down in the rubble underneath some big block, and refuse to move till we were within about two feet of them. Once a Greater Wheatear perched on one of the chimneys of the lighthouse. Saxicola oenanthe cenanthe was not at all plentiful on the island this season. A good many Whinchats (Pratincola rnbetra) were present on i ith September, and we saw a few on other dates between the 2nd and 26th ; four Stonechats {Pratincola torquata) were also seen. Redstarts (Pkcenicurus phcenicurus) were remarkably scarce, and we only saw one Red-spotted Bluethroat BIRD NOTES FROM THE ISLE OF MAY AUTUMN 1910 3 i and was (Luscinia svecicd] : it appeared on oth September as wild as a hawk. On the other hand, Redbreasts (Erithacus rubecula) were more plentiful than usual throughout our stay, and occurred in numbers during the last fortnight of October after we had left the island. Four procured and submitted to Dr. Hartert were pronounced by him to be of the British race Erithacus rubecula melophilus. scarce we saw a Most of the Warblers were uncommonly ; few Whitethroats (Sylvia communis) between 6th and 2 oth September, only one Lesser Whitethroat (Sylvia curruca) on 1 3th September, a male Blackcap {Sylvia atricapilld) on 2nd October, and a female on the I7th, and Willow-warblers between and 26th (Phylloscopus trochilus) 4th September ; there were a good many on the 6th and I 5th, otherwise only one or two. The only new Warbler that occurred was the Siberian Chiff-chaff {Pliylloscopus collybita tristis), a single bird appearing on l6th October (S.E. wind, very light, it constitutes first hazy). We managed to procure it, and the record for Forth, the only others known to occur in Britain being at Sule Skerry, Fair Isle, and Kirkwall. In contra- distinction to last year we were not able to record a single Yellow-browed Warbler, while Chiff-chaffs and Garden- warblers were also conspicuous by their absence. There were more Goldcrests (Regulus regulus] on the this have ever seen there before the May season than we ; largest arrival took place on I4th October, when the island was swarming with these attractive little birds. We procured eight on various dates between loth September and i/th October, and all proved to be the continental Regulus regulus regulus except one, a British example, Regulus regulus augloruiu, secured on I5th September. Hedge Accentors (Pnmella modularis), too, were unusually plentiful, a good many being present on /th and pth October. Those sent to Dr. Hartert proved to be the British race, Prunella modularis occidentalis, excepting one procured on 6th October, " which Dr. Hartert pronounces to be a puzzling specimen, too pale for occidentalis, probably P. m. modularis" A con- tinental specimen of the Great Titmouse (Parus major major') arrived i$th October; it is an addition to the list of birds seen by us on the May. As usual, White Wagtails (Motacilla 4 ANNALS OF SCOTTISH NATURAL HISTORY alba alba) and Tree-pipits (Antlius trivialis trivialis) passed in small numbers,but Pied and Spotted Flycatchers (Mttscicapa atricapilla and striatd) were very uncommon, the former only appearing on 4th and 24th September. We saw more Swallows (Chelidon rustica] than in any previous season, hun- dreds passing on 6th and 1 6th September and smaller numbers often seen in almost case these birds left being ; every the island before mid-day. Siskins were first seen on (AcantJiis spinus) I4th October ; a month later this species was still present on the island. linaria occurred on Many Mealy Redpolls (Acanthis linaria} ; 1 4th October two came in, and another on the i6th. During the fortnight after we left there was an immigration of this species and several were sent to us, all procured being linaria linaria. Holboll's Redpoll (A. linaria holbcelli) was procured, and sent, on 23rd October. Chaffinches (Fringilla ccelebs ccelebs) in small numbers might be seen most days after 3rd October, and Bramblings {Fringilla were one or two arrived on montifringilld) fairly plentiful ; 25th September, and from 2nd October till we left they occurred in numbers on the I ith varying ; they were arriving in flocks all day. We are indebted to Mr. Ross and Mr. Baigrie for having procured and sent off to us several Northern Bullfinches on {Pyrrhula pyrrJiula pyrrhuld) ; 22nd October we received a beautiful male, and the wings and tail of another, which from the description sent with it was a female on the 26th received a evidently ; we two more, male and a female, and on 2nd November yet another male. This is the first time that the Northern Bullfinch has been recorded in Forth. The only Scarlet Grosbeak (Carpodacus erythina) seen appeared on 7th September. We procured it, though, it was much wilder than we have found this species on other occasions it was in the of ; green type plumage. Buntings were fairly well represented this year and were dreadfully wild. Two Yellow-hammers (Emberiza citrinella\ one being a male in splendid plumage, appeared on iith October, and this species (uncommon on the May) was seen again on i$th and 1 7th October. Twice we saw Ortolan Buntings (Emberiza hortulana\ but they were so very wild that we never to within reach of them this managed get ; BIRD NOTES FROM THE ISLE OF MAY AUTUMN 1910 5 species is not new to the island, having been procured there by Mr. Agnew in May 1885. Reed Buntings (Emberiza schceniclns] appeared on i6th and I7th October, and a Lapland Bunting (Calcarius lapponicd) on 4th October (W. wind, strong). We secured this bird, which proved to be a young female, and is the first authenticated record for Forth.
