The (Winter) conditions were and are a major challenge for wildlife – as I write this it’s about 6°C but practically every pond, lake and mere in Shropshire is still covered in ice – and I’m amazed that birds the size of Wrens, Goldcrests and Long-tailed Tits were able to survive such severe and prolonged conditions. They have sophisticated adaptations such as heat exchangers to reduce heat loss through their feet; plumage that provides good thermal insulation and the ability to lay down enough fat during the day to stay warm by shivering through the night, but it’s still impressive in creatures weighing roughly the same as a sheet of A4 paper. I was very impressed by the images on the Devon Bird News blog of Wrens roosting in a House Martin nest.

As we’re barely a third of the way through the winter it’s worth stressing the importance of high energy foods like sunflower hearts and peanut cakes, providing shelter in the form of nest boxes, and maintaining a regular supply of both food and water. Unless we’re blessed with a sustained mild spell most of our wildlife will remain locked down in winter mode, but listen out for singing Wrens, Dunnocks, Blackbirds and Great Tits on sunny days, a sign of hope for the near future.
