NOTES—ORIGINAL AND SELECTED.
where it clung to a twig by its wing-hooks, but flew away after half-a-minute
or so. On the 18th May, about one o'clock, I saw the Bat again flying about
over the lawn. It seemed to fly more feebly than before, with a fluttering
moth-like flight. I went out to watch it, but soon lost sight of it. It had a
most strange out-of-place look as it flew about with its ears fully extended.
Both days were fairly bright, but with a cold wind blowing. The only
suggestion I can make to account for this persistent flying in the day time is
that the bat was prevented from flying at night, as usual, by the fact that
several preceeding nights had been very cold, with frosts; but I saw both
Noctules and Pippistrelles on the wing, notwithstanding the cold.—Miller

[I have on several occasions, in Essex and Hertfordshire, seen Bats flying
by day, but could not be certain of the species; they were not the Long-eared
Bat.—W. Cole.]

Nest of a Black-headed Gull in an old boat.
Nesting of Black-headed Gulls in Essex.—Our member, Mr.
Charles E. W. Hawkins, of Old Hous, Great Horkesley, has for two years
kindly sent us photographs of Blackheaded Gulls nests made in an old boat in
the marshes. In sending the pictures this year, Mr. Hawkins remarks:—
"The enclosed photographs are of a Black-headed Gull's nest, which I took on
May 12th on one of our Essex Marshes, may be of interest. I am glad to say
that there are more uests than I have known for the last twelve years." In
