ZOOLOGICAL NOTES 179 



found no shelter until they came to the west side. By the 5th of 

 May they had almost entirely disappeared. On the 2oth of 

 May I observed a good number of Spotted Flycatchers (Muscicapa 

 grisola) and one Hedge Accentor {Accentor modiilaris) ; and on 

 the 4th of June a male Siskin (Chrysomitris spinus}. THOMAS

The Blue-headed Wagtail in Lanarkshire. It has been my 

 regular practice at the spring migration during the past decade to 

 visit the banks of the Clyde, east of Glasgow, to note the appearance 

 of our summer visitors. The district referred to, as long since 

 pointed out by Gray, is regularly visited by a large colony of Yellow 

 Wagtails. On the 24th of April this year, on a little patch of vegeta- 

 tion in the stream below Cambuslang, I saw with my binocular, at 

 about fifteen yards from the river bank, what I had supposed was a 

 Yellow Wagtail, but it proved to have, to my surprise, a gray-blue 

 head. It removed to another patch of vegetation at no distance 

 from the first, but presented, as before, its back elevation, and in a 

 minute afterwards flew to a tree on the right bank of the stream, 

 whence it went to the fields on that side. I returned to this neigh- 

 bourhood on the following evening, and had the good fortune, after 

 waiting a little, to see the bird of the previous day on a patch of 

 green close to the right bank. It shifted after an interval to one of 

 the islets near the left bank, where I saw it quite favourably, noting 

 anew the gray-blue head and the snow-white line over the eye, which, 

 by the way, when seen directly in line with the spectator, gave the 

 head a curiously puzzling appearance as it was slightly diverted to 

 right or left. The bird in appearance was a cock Yellow Wagtail 

 with the conspicuous differences mentioned, and being quite familiar 

 with the yellow head of Motqcilla rail I could not make the mistake 

 of confusing M. ftava with its congener. To give an idea of the 

 richness of this district in Wagtails at this season, I may say that on 

 the forenoon of the day on which I saw M. flava I also saw half a 

 dozen M. raii, as many M. alba and M. htgubris, and a pair of 

 M. melanope. After the 25th I did not again see the Blue-headed 

 Wagtail, but the river was in partial flood for some days thereafter, 

 and the " islets " patches of vegetation which indeed scarcely 

 deserve the name were covered. On the i5th of May I saw about 

 twenty M. raii on the river-bank over a stretch of three or four 

 miles. JOHN PATERSON, Glasgow. 



Golden Oriole in Forfarshire. This morning (8th June) we 

 had brought to us a specimen of the Golden Oriole (Oriolus galbula), 

 a female, in most excellent plumage. The story which accompanied 

 it was to the effect that it had been flushed at dusk (about 9 P.M.) 

 the previous evening, in a narrow strip of wood about two miles 

 north-east of Arbroath and about a mile from the sea ; and that, on 

 being disturbed, it had flown against a tree trunk and injured itself.
