where it clung to a twig by its wing-hooks, but flew away after half-a-minute 

 or so. On the i8th 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

 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.]

 that there are more nests than I have known for the last twelve years." In
