NOTES ON PALLAS’S WILLOW WARBLER AND SOME 
OTHER RARE EUROPEAN WARBLERS.

Read 23rd February, 1897. 
One of the most interesting additions that has of late been 
made to the avifauna of the British Islands is certainly that 
of Pallas’s Willow Warbler, Phylloscopus proregulus, a single 
example of which was shot at Cley-next-the-Sea, Norfolk, on the 
31st October, 1896, by Mr. Ramm, who forwarded it to 
Mr. Thomas Southwell, and informed that gentleman that he 
“found it amongst the long grass on the bank or sea-wall, not far 
from the sea at Cley, a locality which has produced many rare 
migrants, and at first took it for a Goldcrest, but on approaching 
to within two or three yards, the bird being very tame, he thought 
he recognised a Yellow-browed Warbler, a species he had seen 
before, and therefore secured it.” Mr. Southwell identified it 
correctly as Pallas’s Willow Warbler, but forwarded it to me for 
confirmation, and at his request I exhibited it at a meeting of the 
Zoological Society on the 1st December last. On comparing this 
bird with those in my collection from Siberia and the Himalayas, 
it agrees most closely with a fully adult bird from Siberia; and 
I may here state that it is an adult female in very fresh plumage, 
and is quite as bright in tinge of colour as any Siberian specimen 
I have seen. Mr. Giitke, whose recent death, though at a ripe old 
age, lias deprived European ornithologists of one of its best and 
most reliable out-door observers, held the view that the form from 
'Siberia was sufficiently distinguishable from that found in the
