210 THE ZOOLOGIST. 



I have made the following further notes on species mentioned 

 in my former papers : — 



Dipper. — I saw a Dipper in the Afon Ehyd-Hir, near Hendre pen 

 prys, on the 26th May. On the coast near Aberdaron there is a little 

 narrow cwm where the Afon Saint comes down, emerging from a 

 tunnel, partly natural, into a narrow chasm with a tall ivy-clad rock- 

 face on one side. It is a very pretty place with luxuriant vegetation, 

 the rocks being decked with clumps of hart's-tongue fern and gigantic 

 plants of the wall-pennywort (Cotyledon umbilicus) a foot or eighteen 

 inches high. The sides of the cwm spread out into broken ground 

 lower down, overgrown in parts with gorse and bramble bushes, a 

 favourite haunt of the Red-backed Shrike. The Dipper has often 

 nested inside the little tunnel ; also in Aberdaron Mill, and this 

 season at a spot some way up the Afon Fawr. Mr. Cummings tells 

 me he saw Dippers on the Afon Geirch, near Edeyrn, in August, 1901 ; 

 and Mr. Caton Haigh says it is common on the Erch, and that he has 

 seen it in the Bod-y-groes river, and once in a little ditch near Coed 

 Rhos fawr. Nevertheless the Dipper cannot be called a common bird 

 in Lleyn, and you can go about the country a good deal without 

 seeing one, a thing you can hardly do in some parts of North Wales. 



Grey Wagtail. — This also bred in the chasm at Porth Saint, on 

 shelves in the rock, for several years ; but this season the birds had 

 probably changed their nesting-site for some spot in the ivy-clad cliff. 

 I saw a full-fledged young one there. 



Red-backed Shrike. — I saw a male perched on the bramble bush 

 in the upper part of the cwm in which I found the nest the year before ; 

 also a pair about the foot of Mynydd Mawr, and another pair not far 

 off near the most westerly farm, close to Gwddel Moch, which had a 

 nest ready for eggs in some bramble on the top of a bank dividing two 

 little fields. This bit of country has a warm aspect, being sheltered 

 by Mynydd Mawr, and the broken ground is well clothed with gorse 

 and brambles. I also saw a female Shrike at Nevin. Mr. Cummings 

 has seen a pair with young at Aber Geirch, near Edeyrn, on the 1st 

 August, 1901. 



Goldcrest. — Seen at Bodfean and Llanbedrog. It has been known 

 to strike against the lighthouse on St. Tudwal's. 



Whinchat. — Quite uncommon. In 1902 I only saw two, both near 

 Nevin. Mr. Cummings saw one at Abersoch in June, 1901. 



Bullfinch. — Not common. A pair at Bodfean. 



Coal-Tit. — One at Bodfean. 



Tree-Creeper. — Bodfean.
