BLUE-HEADED WAGTAIL IN HERTFORDSHIRE. 
In a pasture bordering one of the reservoirs at Tring, on 
April 29th, 1917, my sister-in-law detected a Wagtail differing 
in colour from the Ray’s Wagtails with which it was con- 
sorting. As we looked down from the top of the reservoir 
embankment on the birds running to and fro in the short 
grass, it was an easy matter to distinguish the stranger by 
its blue-grey crown and nape, the conspicuous whitish buff 
superciliary streak, the less distinct streak of the same colour 
through the ear-coverts, and the buff wing-bars. The upper- 
parts and ear-coverts were greyish-brown, the breast and 
belly pale yellowish-buff passing into bright sulphur-yellow 
on the under tail-coverts. I cannot say positively to which 
subspecies of Motacilla flava the bird, a hen, belonged, but 
the blue-grey crown and the pale ear-coverts point to M. f. 
flava, the subspecies, apart from MV. f. rayi, most likely to 
occur. Cuas. OLDHAM. 
PRESENT STATUS OF NUTHATCH IN CARNARVON- 
SHIRE AND ANGLESEY. 
On May 5th, 1917, Mr. F. H. Mills of Bangor sent me a 
specimen of the Nuthatch (Sitta e. britannica), which had 
been found dead at the foot of a tree in Vaynol Park. The 
species appears to be establishing itself along the Menai 
Straits for it has been recorded on the Anglesey side by myself 
in 1910, and Mr. R. W. Jones in 1914 : while on the Carnarvon- 
shire side it was noted in Penrhyn Park by Mr. C. Oldham in 
1912, and at Llandwrog by Mr. S. G. Cummings in 1914. 
Prior to this the only record was a bird seen at Bodwyn, 
Carnarvon, in 1902. As a whole the evidence seems to 
indicate that the species has extended its range thus far west- 
wards only within quite recent years. Around Llandudno 
it has become firmly established during the last ten years.

GREAT GREY SHRIKE IN WILTSHIRE. 
My friend, Miss Margaret Butterworth, saw a Great Grey 
Shrike (Lanius eacubitor) on April 18th, 1917, about a mile 
and a half from Lechlade, on the road to Highworth on the 
borders of Wiltshire and Berkshire. She knows all our 
common birds well, including the Red-backed Shrike.
