Aggressive Blue Tit!

Mon 24 Aug, 11:23

Heard s blue tit kicking up a hullabaloo this mng in garden. Open door to see said blue tit noisily, and with appropriate wing opening gestures, seeing off a grazing butterfly. I didn’t have time to ID said butterfly except its dark underwings.
A quick search on bird sites informs me that the Peacock butterfly with it’s beautiful “eyes” is indeed  eyed as an aggressor by blue tits, scared of something flying with such scary eyes ( which of course is why the peacock has them to deter attacks)
