experience of other mornings, I have no doubt that they soon 
followed the others. 
On cloudy mornings they are much more reluctant to leave 
their roosting-places. In the daytime, if there be much wind, 
they choose the more sheltered side of the rocks, where they may 
be seen in flights of from forty to sixty, often poising themselves 
against the breeze with head and tail depressed, the latter spread 
fan wise and showing the beautiful white spots. On one windy, 
stormy day I saw them flying about the streets of Mentone. I 
was surprised to see them so far from their favourite rocks on 
such a day. I do not believe that they ever go any distance inland 
at this time of year. Martins have been frequently seen to the west 
of the Bay of Mentone, about Cape Martin and Roccabruna, but 
I believe these to be another lot roosting at or near Cape Martin. 
On this point, however, I cannot speak at all positively. These 
birds are, I am told, sometimes seen in the winter at Nice, which 
fact is mentioned by Dr. Bree in his f Birds of Europe/ being, 
as far as I am aware, the only recorded instance of their having 
been seen in winter in any part of Europe, with the exception of 
Greece. I do not imagine that the number of the Martins 
wintering in the neighbourhood of Mentone could be much 
more than 150; certainly, I think, not under 100; but there 
may be more than I know of. They retire to roost from 4 to 
4.15 p.m., varying according to the state of the weather, and 
observing much the same course of proceeding as in the morn¬ 
ing, except that they seem to settle down into their places more 
quickly.

Sir, — On the 17th of November I received an adult speci¬
