178 THE SCOTTISH NATURALIST 



April there are many notes from our southern stations of the arrival 

 of Meadow-pipits, probably our own birds returning to breed with 

 us. Stations in our Northern Isles record arrivals from 8th April 

 steadily up to 15th May, on which latter date many are also recorded 

 at the Butt of Lewis. These doubtless refer to the passage of the 

 more northern breeding birds on their way overseas, and the notes 

 from the Isle of May during this period probably also belong to this 

 category. 



The autumn movement is first noted on 27th July, and our 

 southern stations record movement, doubtless our breeding birds 

 leaving us, up to nth September. The first record of movement 

 from our Northern Isles is on 17th August at Swona, and there are 

 spasmodic notes of arrivals in the northern archipelago and the 

 Outer Hebrides up to 14th September. A strong movement, 

 without doubt an overseas arrival, took place in the above localities 

 from 30th September to 21st October, after which the only records 

 are, one in Largo Bay on 17th December, and several on the moors 

 at Corsemalzie on 28th December. 



The Rock-pipit, Anthus spinoletta petrosus. — Arrivals of Rock- 

 pipits are reported from the Isle of May on 12th March, and Hoy 

 High on 2nd April, and one was killed at the Little Ross lantern on 

 nth April at 11.30 p.m. 



A few appeared on Skerryvore on 31st July, numbers are noted 

 at North Unst on 4th September and the Butt of Lewis on 9th 

 October, a flock of thirty at Swona on 15th October, and a party of 

 nine flying to the south-east out at sea off Craignarget, Luce Bay, on 

 22nd October. Some of the above records may refer to A. s. 

 litt oralis. 



The Blue-headed Wagtail, Motacilla flava flava. — Birds 

 of either this or the Grey-headed form {M. f. thunbergi) occurred 

 at Fair Isle on i6th, iSth, and 26th October. See p. 151. 



The Yellow Wagtail, Motacilla flava rayi. — This Wagtail 

 is first recorded from Beith on i8th April, Summerston on ist, 

 and Darvel on 2nd May. After this arrivals are noted up to 

 6th May, and on 21st May one is reported from the Island of 

 Noss. On 1 8th August a male Yellow Wagtail is noted at Corse- 

 malzie, one at Beith on i6th September, and one at the Isle 

 of May on 28th September. 



The Grey Wagtail, Motacilla cinerea cinerea. — A party of 

 eight Grey Wagtails was seen in the Lahill burn on 8th February.
