Interesting. I find my Hooligans to be very alert to the hawk (who incidentally has really worn his welcome thin - he is around ALL THE TIME) but they ignore the crows who returned today.Observations
Some crows just flew overhead and Lady Featherington just gave the alarm. The three of them ducked into the courtyard. The Big Girls looked up and kept at what they were doing.
Hoping the crows see off the hawk like they did in the past but I am not optimistic.
