12 REPORT ON THE MIGRATION OF BIRDS. 



In autumn, earliest record at Isle of May on Aug. 16th, — 

 Whitethroat, — when almost a rush might be recorded. On the 

 23rd again, at same place, large numbers of Whitethroats and 

 Titmice. At Cromarty station Eobins reappeared, about a dozen 

 being seen on Sept. 15th, the first since spring. On Sept. 15th, 

 a rush of Eobins at Isle of May, and on 22nd. Winds on 

 all these dates easterly, with fog, and on 15th *' flying banks 

 of fog." Eecords also of Blackcap on 10th, and more Blackcaps 

 on 2Brd ; that on 10th with light W. wind, the others light E. 

 No records in October except at Chanonry, two on 15th, strong 

 squalls and S.W. Small numbers beginning of November, 

 amongst Thrushes, &c., q. v. stations ; Pentland Skerries, light ; 

 Dunnet Head, one record ; the latest on Dec. 28th ; and 

 Jan. 30th, at Chanonry ; light squalls and sleet. Bell Eock and 

 Isle of May (maximum). Blue-throated Warbler on night 

 of Sept. 2nd — 3rd. In all three species. 



Philloscopin^. — In spring a distinct movement of Gold- 

 crests, but nothing to compare with the autumn rush of 1882, 

 though comparing favourably with the spring rush of the same year. 

 Earliest record, April 1st, Isle of May; then singly or in small 

 numbers till 13th, when rather more, along with other species. 

 Latest date of Goldcrests or other Leaf-warblers, April 16th, at 

 Pentland Skerries; one Goldcrest ; light N.E., clear. The first 

 Chiffchaff on April 26th; also at Isle of May; wind S.E. and 

 haze ; and some again on May 2nd ; and Willow Warblers and 

 Chiffchaffs on May 15th. 



In autumn a rush at Isle of Ma}^ and no previous records ; 

 on Sept. Brd (see Saxicolince) ; on the 2nd a S.E. gale, changing 

 light W., very dark. Scattered records running through 10th, 

 11th, to 15th, when another rush of Willow Warblers and Chiff- 

 chafi's, and a solitary Goldcrest on 22nd, with a rush of Eobins. 

 Goldcrests did not put in an appearance much before Oct. 10th, 

 when a rush took place that night, with light E. wind and cloudy, 

 again at Isle of May. Mr. D. M. Scott speaks of the " smallest 

 wrens he ever saw," which were seen at Sumburgh Head, on 

 Oct. 28th, which were probably of this species. Stations 

 recording are Sumburgh Head (one record) ; Tarbat Ness (one 

 record on Oct. 30th [some years Caithness gets a large share 

 of Goldcrests] ; and Isle of May. Three species.
