There is always birdsong in my garden at this time of day , but see how silent the garden is in the snow. I was told a long time ago that you will never hear birds singing when it is snowing as birds only sing when they are happy. Snow and freezing cold weather can be lethal to our garden birds and they perch in silence waiting for the storm to stop. This why snow and silence go together.
In a few hours the snow covered everything – birds food, food on bird tables, their water and often their shelter. A lot of birds roost in the hedge, but the snow was blowing inside the hedge as well – there was no escape from the snow.
