Tits, Peckers and Nuts

I watched two rabbits yesterday evening which were so engrossed in some curious ritual behaviour that they were oblivious to me a few feet away. They would lollop along for several paces, then turn and crouch, facing each other with their noses almost touching, and stay like that for ten seconds or so, before repeating the whole exercise. This didn't quite fit with usual rabbit mating behaviour, which involves a degree of breathless chasing and resting, before the male stops a few yards away and squirts a jet of wee over the object of his desires. Apparently the female's reaction to this varies; she either shows complete indifference or takes flight and scampers off.

This is not a pulling technique I ever tried. I'm fairly confident, though, that it would have triggered the 'flight and scamper' response, like most of my other chat-up attempts.

I didn't have my camera with me and anyway, depending on what the rabbits had in mind, snapping them might have seemed prurient. Instead, here is a picture, also taken last night, of our local woodpecker looking for nuts. The unattractive metal post is intended to deter rats (they still manage to climb up); the string to deter crows, which otherwise fly off with the entire feeder. Any suggestions as to what the tit is saying are welcome.
