I read somewhere that a naturalist found fifteen wrens huddled together for warmth last winter in a nest box one night.
We are very lucky in that we have plenty of house sparrows here. They are supposed to be less common than they were but that is certainly not true here where during the day our holly hedge makes a deafening sparrow noise. We have noticed that when we sit in the sitting room and have our afternoon tea, outside the windows there is a constant stream of sparrows flying up in front of the window. We have discovered where they are going - they spend their nights huddled together in the house martins' nests under the eaves.
Although it is less cold here and the fog has mostly gone, it is still winter. And as a friend quite rightly pointed out this morning - February is often an awful month. I am hoping that she is proved wrong and that at the very least our snowdrops will be out and we will be reminded that spring is only just around the corner.
