BIRDS OF ANGLESEY AND CARNARVONSHIRE. 313 
combat. When we have descended again into the valley we find 
a Chaffinch’s nest containing five eggs, and also come across two 
other empty ones of the same species. From close by a Green 
Woodpecker calls out its loud laughing note, and the other birds 
we see in going along include a pair of Tree-Pipits, Chiffchaffs, 
Wood-Wrens, and Willow-Wrens. At about 9.45 in the evening 
we hear the seven times repeated whistle of Whimbrel, as a flock 
of them pass overhead in a northerly direction. 
A4th.—We cycle to Castle Rock in Red Wharfe Bay, Anglesey, 
where Stock-Doves are known by us to breed. As we approach 
the precipitous side of the rock a Kestrel is seen to leave it, 
and a flock of Jackdaws that nest in the numerous holes start 
to fly around, ‘‘ dawing” the whole time. A large number of 
Stock-Doves leave their nesting-holes, which we notice are nearly 
all at the top of the rock. When we reach a place where we 
can ascend we do so, keeping close to the edge when walking 
along. Some more Stock-Doves leave their nesting-holes, but 
only two of these are accessible, the one containing a single 
ege, and the other a couple of young a few days old. Coming 
to the place whence we had seen the Kestrel leave, we once 
more disturb it, but now we can look down and ean dis- 
tinguish its four ruddy eggs laid in a slight scratching on a 
grassy ledge. The same day we observe Swifts and hear the 
Corn-crake.
