Sitting in my living room yesterday, late PM, I saw a smallish bird swoop in and settle on a roof opposite. Slightly smaller than your average pigeon, http://www.rspb.org.uk/wildlife/birdguide/name/k/kestrel/index.aspx The bird sat for about a minute, head quickly darting from side to side. It flew away, dipping down below the roof line and then up and over the house and gone. Very graceful. Anybody else?
