THE BIRDS OF BRECONSHIRE. 45 
WHITETHROAT, Sylvia cinerea. 
Very common here. Welsh, FY gwddf- 
wyn cyffredin. 
LESSER WHITETHROAT, 
Sylvia sylviella. 
Rare; I have seen it on_ several 
occasions. My youngest son took a nest 
of this bird, containing eggs, at Tynycae, 
near Brecon. Others have noticed it 
from time to time. Like many of our 
migratory birds (notably the Spotted 
Crake), it probably visits various places 
in the county year after year, whilst 
others are constantly avoided. 
WOOD WREN, Phylloscopus sibilatrix. 
The rarest of these three warblers. 
Welsh, Canwr y coed. 
WILLOW WREN, Phylloscopus trochilus. 
Fairly common. Welsh, Srychydd yr 
helyg. 
CHIFF CHAFF, Phylloscopus rufa. 
I do not consider it to be quite so
