A bit of a flurry going on here, this is in our newly aquired meadow at the side of the house, there wasn't much boxing - just a very determined attempt by the male to mount the female, she threw him off a couple of times but he succeded eventually. Again my main regret was the distance was a little too great and I was fighting the light.
As luck would have it, the male returned yesterday morning........he was closer this time.
