Two Tiny Bullies

Warm & pleasant so I went to Kladow .On going to check the Spider Web Bars I spotted this pair  of swallows .How nice one may think .Then this elderly crow came walking down to me for a treat .He took it to enjoy and what should I see but the "dynamic  duo" set about him and fly around his head butting it ,Almost as a wasp comes at us, They are very fast & he was bewildered .Cross with myself as had not switched movie button on as I thought .As the saying goes ,dynamite comes in small bundles and poison in very little bottles .... These must be the  Swallow delinquents ..No problems with any of the others .
