What passes for foreplay amongst Oystercatchers (Haematopus ostralegus)

Having started this set yesterday, I figured I'd better finish it up. You'll want to know how they got on.
I didn't see any courtship rituals that preceded this mating, just the female tipping her body forward with a quick backward glance and he hopped onto her back. But that's not to say there was no "romance" or feelings involved.
