Williamson's Weekly Nature Notes

One year in this garden I watched about 23 wrens as the sun set, swarming over the house like little mice.

Every night throughout January of that year with a frost settling they gathered as regular as clockwork. Then, just half an hour after the sun had gone, they would all vanish.

I thought they had found a niche under the eaves and squeezed their way into our dusty, deserted loft where the bats were fast asleep.

However, I kept careful watch and, to my amazement, watched the whole tribe disappear one at a time into an old tit nest box attached to the coal house.
