More Birds - Less Snow

Last night my husband saw an owl fly over the garden, possibly a barn owl; this morning a heron flew over. Today it is much warmer than it has been with temperatures around plus three or four; this means the snow is melting. Not much else is happening in the garden as it is much too cold to work in the garden always supposing that I could see the ground under the remaining snow. I hope the fish in the pond are still alive, but there is no way to tell as they are likely to be lurking at the bottom of the pond where it will be slightly warmer.
