crows & gulls

[nightshade]

I was low speed parked as usual when I noticed a sloping field with a good mix of crows and small gulls,to my suprise they seemed to having some sort of ritual fight
First a gull then a crow would take off and wheel and dive at each other then land as if nothing had happened and continue feeding this continued across the field randomly at least half a dozen times before I moved out of view always one of each really odd
