gunsliot, not apparently from sliynoss, but seemed rather to miss 
coming near tlio boat than to avoid it. Tireless, indeed,, appeared 
to be the wing of this species, their mode of progression — two or 
three short flaps of the pinions, and then a glide close to the surface 
of the waters — constantly withal changing their course, was con- 
tinued as far as the eye could follow. Only once did I see one 
settle on the water, and then only for a few seconds, apparently to 
secure a fish. 
[In reading Mr. Power’s interesting notes the following remarks suggest 
themselves. In August, 18S0, we liad a remarkable passage of Redstarts at 
Cromer. I counted twenty-nine in three days, a thing quite unprecedented, 
as it is at any time an uncommon bird with us. They were noticed passing 
in the same manner at Flamborough Head (Zoologist, 1880, p. 486), and at 
Tees-Mouth (Zoologist, 1881, p. 25), and at Cloy, as appears from Mr. Power’s 
remarks. The capture of tlie Blue-throated Warbler, the second ever killed 
in Norfolk, is a matter of great interest. Mr. Power having kindly sent it 
for exhibition I have been able to compare it very carefully with the plates in 
Dresser’s ‘ Birds of Europe,’ from which I make it out to be the white-spotted 
species (Cyanecula Wolfi). The first Norfolk specimen, picked up dead in 
September, 1841, was the red-spotted species, an adult bird (Zoologist, vol. i. 
p. 180). Mr. Dresser figures C. Wolji in seven plumages on three plates. 
Mr. Power’s specimen agrees fairly with the right-hand figure on plate No. .‘B : 
also with the skin of a bird shot in Egypt, which I have always considered to 
belong to C. Wolji. The breast-spot in Mr. Power's bird is now almost pure 
white, the slight tinge of yellow having nearly faded. With four exceptions, 
which have severally occurred in Kent (Zoologist, 1853, p. 3945), the Isle 
of Wight (Zoologist, 1866, p. 172), Yorkshire (Zoologist,' 1876, p. 4956), 
and the Isle of May (Zoologist, 1881, p. 451), all the Blue-throats which 
have hitherto occurred in Great Britain, have belonged to the red-spotted 
(C. suecica). It is worthy of remark that the day after Mr. Power shot his 
biifl, another was obtained in Kent (Zoologist, 1881, p. 471), but this proved 
to be the red-spotted (C. succica). 
The westerly migration of the great flocks of Waders in September, 
observed by Mr. Power, at a time when we should have expected them to bo 
following the coast-line m a south-easterly direction, shows how much there 
is still to be learnt on this subject. It is a great subject for inquiry ; but I 
am quite sure that the tabulated returns of many years must be_ collected 
before any decision will be arrived at with any thing like certainty. At 
Cromer, the Gull tribe of all kinds, at all seasons of the year, are almost 
invariably to be seen going west. In addition to the notes printed I 
may add, that on the 6th of September, 1881, Mr. Power saw a bird whicli 
he believed to be a Glossy Ibis, which I have no doubt was the case, as on the 
16th of that month one was shot at Lynn, and others have occurred tliis 
year.— J. II. Gukney, Jun.]
