W. BICKERTON-NOTES ON BIRDS 
Red-Throated Diver (Golymbus sept'entrionalis ).—The Hon. 
Walter Rothschild reports a female of this species shot at 
Wilstone Reservoir on January 14th. This bird was only placed 
upon our county list last year for the first time, a specimen 
then having been also reported from Tring. 
The following birds have been reported as being scarcer in the 
county during 1910:—Blackcap, brambling, nightingale, cuckoo, 
redwing, golden plover, yellow-hammer, owls (all species save 
the little owl), hawks, woodpeckers (all three species), tree- 
creeper, nuthatch, snipe, grasshopper-warbler, red-backed shrike, 
and crossbill. 
On the other hand, the following have been reported as more 
plentiful:—G-arden-warbler, redwing, liouse-martin, thrushes, 
blackbird, goldfinch, bullfinch, little owl, marsh-tit, starling, 
wood-wren (slightly), linnet, pied wagtail, heron, redshank, 
landrail or corn-crake, and great crested grebe. 
This concludes the tenth annual report on birds which I have 
had the pleasure of preparing for the Society, and in recording 
this fact I can only say again, and with added emphasis, how 
grateful I am for the loyal support that our local recorders all 
over the county have given to me, and how sincerely I appreciate 
their continued assistance. Without such active co-operation it 
would manifestly have been impossible for anyone to collect and 
present to the Society such a considerable body of information 
as to the seasonal and annual happenings in the bird-world of 
Hertfordshire.
