efforts of both birds to endeavour to obtain food for the brood. They would 
thus be without, or scantily supplied with, the two great necessaries at that 
tender age—food and warmth. If, therefore, the young Martin were as 
tender as the young Blackcap, would it not be in great danger of perishing 
much more frequently than it even now does in this fickle climate? Even 
young birds which can endure loss of food and warmth for sixty-two hours 
must at last succumb to such unnatural conditions; and as the season 
advances and food grows scarcer, whilst the temperature at the same time is 
falling lower and lower, it does not appear wonderful that the late broods of 
Martins should perish; and then, but perhaps not till then, the sorrowing 
old birds should take their departure to warmer climes, leaving their callow 
brood dead in the nest. May it not be, therefore, that these birds perish, not 
because their constitution is more tender than that of other birds, but 
notwithstanding their powers of endurance being exceptionally great ?—

CaLL-NOTE OF THE YOUNG GUILLEMOT AND RazoRBILL.—Will any 
one kindly inform me if the call-notes of the young in these species are 
distinguishable? I am led to ask the question from a paragraph of the 
late Dr. Saxby, in his ‘ Birds of Shetland,’ where, writing of the Razorbill, 
he says :—* The cry of the young bird is very peculiar, something between 
a chirp and a whistle, but more resembling the latter.” At the head of his 
chapter he also gives “ Willock” as the local name of this species in 
Shetland. It occurs to me that this name is descriptive of the cry of 
the young bird. ‘The cry of the young Guillemot, as I have heard it at 
Flamborough (and which is peculiar to the young only) may very well be 
represented by the same word “ willock,” and I have heard fishermen use 
it in imitating the note. Macgillivray, in his ‘ British Birds’ (vol. v. p. $18), 
gives “ Willock” as a local name of the Common Guillemot; and on the 
east coast in some districts the name seems common to both species. At 
Flamborough the Guillemot is universally called the “ scout,”—“ Flam- 
borough scouts,”—the name by which they are known both on the Yorkshire 
and Lincolnshire coasts. When heard at any distance the cry of the young 
Guillemot has a certain resemblance to some high notes of the Merulida, 
and it may very well be called a clear whistle quickly repeated, having a 
resemblance to the words “ willock—willock.”. When at Flamborough 
early in August, I repeatedly heard this peculiar call of the young, both 
from the cliffs aud on the sea; and, in the latter case, captured young 
downy Guillemots, so as to be certain of the species. Although there 
were countless numbers of Guillemots along the coast, I did not see a 
single Razorbill; they appear to have left with their young about the last 
week in July. I got a good series of eggs, taken there in the spring, aud 
was told they had bred in large numbers, However, on August 6th, not
