I had to look upwards again today when I heard a familiar tap-tap-tap high up in next-doors old oak tree. I’d noticed it first a couple of weeks ago, but until this morning the culprit had eluded me. I was just leaving the house with my dog Charlie for his daily walk, when I heard the tapping again, a hollow vibration echoing through the clear morning air. I stopped and gazed upwards into the oak tree, scanning up and down the trunk and branches, and listening out for the sound again. Finally I saw him – a greater-spotted woodpecker – perched high up on a branch. I watched for a brief moment, then there was a flash of red under-belly and he was off, swooping across the pale blue sky, and leaving me with the feeling that spring is just around the corner.
