Wandering around Richmond Park yesterday, near Two Storm Wood north of Sawyer's Hill, where the rabbits hang out, I noticed something that I've never seen before. There were a lot of what looked like juvenile carrion crows around (as is the case all over the park, not just the rabbit-y bits), and I saw several of them pecking at grazing rabbits. Sometimes quite sneakily: a rabbit might be munching contentedly in the shade of a fence post, let's say, and a crow wanders around the back of the post and gives the rabbit a good peck on the arse. Rabbit hops off a little bit. Crow follows, gets in a peck. It didn't seem to bother the rabbits too much, for their burrow entrances were nearby and they didn't feel the need to hide.
Are the crows feeling out if they could kill a full-grown rabbit?
