That reminds me... working in the garden yesterday, all the local crows converged together to mob a heron that was passing by. Felt rather sorry for the heron, as I see it pretty much daily flying between two bodies of water, so I don't know why the crows had decided to gang up on it.Enjoyed a good view of a cuckoo being harried by meadow pipits on my lockdown walk in the Pentland Hills yesterday.
