380 THE ZOOLOGIST. 



nor did I hear the note of this bird. Not only were Willow Wrens 

 singing in the brambles and stunted thorns which grow beside 

 Llyn Maelog, but numbers of them were moving about in the 

 extensive reed-beds, singing and feeding. 



Other migrants arrived with them; Common Whitethroats, 

 Sedge Warblers, Cuckoos, Corn-Crakes, Swallows, and Sand- 

 Martins were all in greater numbers on May 2nd than I had 

 noticed previously ; Dunlins, Einged Plovers, and Turnstones 

 were more abundant on the beach, and there was a fresh arrival 

 of White Wagtails. On this day, too, I saw my first Swift and 

 Whinchat. 



The numbers of the Willow Wrens remained about the same 

 for a day or two, but they soon diminished, and by the middle of 

 the month all but the local birds had departed. On two occasions 

 later I saw a Willow Wren singing from the top of the wire 

 covering of a chimney in Khos Neigr village. 



Wood Wren. — The Wood Wren is absent from the immediate 

 neighbourhood of the western coast, so that I do not know when 

 it arrived. I did not hear any in the woods which bound the 

 Straits on April 25th, but there were many singing to the south 

 and east of Llanfair P. G. on May 3rd. Two were in song in the 

 woods at Llangefni on May 5th. 



Sedge Warbler. — On April 18th the first Sedge Warblers 

 appeared in the reeds at Llyn Maelog ; after that date a few sang 

 daily and in the evening until May 2nd, when apparently the 

 local birds arrived, for from that time the bird, which is abundant 

 in the district, was common. 



Grasshopper Warbler. — The Cefni marsh, where the Holyhead 

 Eoad crosses the river, is a locality where we have several times 

 heard and seen the Grasshopper Warbler. It was here, on April 

 25th, that a friend heard the bird singing ; on May 2nd I found 

 it in its usual place. The first bird I heard in Ehos Neigr was 

 trilling on April 29th in a field enclosed for building purposes 

 and allowed to run waste ; I heard another here — perhaps the 

 same bird — on May 15th, and one at Llangefni on May 18th. 

 The bird is much less plentiful in this part of the island than in 

 the east. 



Dipper. — In 1904 we added the Dipper to the list of birds 

 which we had found nesting in Anglesea. I visited the spot
