192 THE SCOTTISH NATURALIST 



The Wren, Troglodytes troglodytes troglodytes. — A good deal 

 of movement of Wrens in ones and twos is recorded from our 

 Orcadian stations up to i6th April; they were at the Killantringan 

 lantern on nth and 14th April, and one was killed at the Skerry vore 

 lantern on 4th May. 



On 25th July and loth August, and from ist to loth September, 

 a Wren visited Pentland Skerries, and on 4th (one) and 9th (two) 

 August the species is reported from the Muckle Flugga lantern 

 (7! t. zetlandicus ?) From 22nd September to i8th November 

 small numbers on the move are noted from stations in Orkney, 

 the Butt of Lewis, Kyleakin, the Isle of May, Tarbatness, and 

 Little Ross. On 5th December one was on Pentland Skerries, and 

 two there on i8th December, while on loth December a few 

 were on the Isle of May. 



The Swallow, Che lido n rustica rustica. — The first record is 

 early, and is from Bardowie (Clyde) on 5th April ; the next are 

 Beith on 13th April, the Blackadder on 15th, Duddingston on 

 1 6th, and Darvel, Johnstone, and Troon on 17th April. Notes 

 of arrival come steadily after this up to 15th May, by which time 

 our summer visitors seem mostly to have settled down. The 

 first island record is from the Butt of Lewis on 3rd May, and 

 from 5th May to the end of June there are constant records of 

 Swallows, probably mainly passage migrants from stations in our 

 Northern Isles and Outer Hebrides. 



A few were about Fair Isle from 6th to gth July and from 

 8th August, when " few left " is recorded from Dunkeld, up to the 

 end of September departures are reported constantly; the height 

 of the movement seems to have been from 20th to 27th September. 

 On 12th September one, probably a passage migrant, was seen 

 at North Unst. Last seen Beith on 2nd October, Largo and Mel- 

 rose on 5th, Meggatknowes, Yarrow, on 7th, West Renfrew on 

 8th, Darvel on 15th, Bathgate on i6th, and Alticig shore (Luce 

 Bay) on 27th October. 



The House-martin, Hirundo iirbica_ urbica. — Is first noted 

 at Holy Island (two) on 12th April, and Kilconquhar Loch (E, Fife) 

 (one) on 20th April. The general arrivals were late this year and 

 did not take place till the first week of May ; during this time 

 many notes come from all over Scotland of the return of breeding 

 birds. By i6th May the tale of nesting birds seems to have been 

 pretty well complete. On i8th May House-martins are recorded 

 from Fair Isle and the Island of Noss, and up to 15th June
