10.30 a.m.: Four carrion crows are foraging towards the lower end of the parkland below the Obelisk Lodge at Nostell. I’m guessing that there are two males and two females because two of them are bowing and cawing: rival males. This genteel approach to courtship doesn’t last long.
The rivalry erupts into a scrap as the males go for each other. At one stage, one of the males briefly ends up on his back, defending himself with legs and beak. Despite the fracas, the foursome stays together as we walk off up the slope.
