Went on a largely pointless wander around Serpentine BP this morning. The windswept moonscape was strangely devoid of birds.
I was just leaving when a cacophony of Long-tailed Tit calls alerted me to Something Going On in the hedge by the road. I've never heard such a racket. My guess was that there was a dozing Tawny Owl in there, but after a minute or so, the noise reached new, shrill levels, with added squealing Blue Tits, and a big female Sparrowhawk flew out over my head and off down the hedge to have a go at catching something there.
Always nice to have close encounters with raptors.
