Peregrine : hunting lapwing : Frampton Marsh

I caught sight of a bit of a commotion out of the corner of my eye whilst I was busy filming in another direction. This Peregrine (Falco peregrinus) was chasing Lapwings over an area of water in the saltmarsh adjacent to RSPB Frampton Marsh in Lincolnshire, UK.
It had several attempts at what I think were different birds - however, I might be mistaken and maybe two of the attacks were on the same bird. First attempt missed completely; in the second, the Peregrine took down the Lapwing, but it swiftly recovered and took off again. There were several Marsh harriers around, and I think these coralled the Lapwing and enabled the Peregrine to have another go. Again, it managed to take down the Lapwing, but I think (it was difficult to tell as everything was happening quite fast) that the Marsh harriers ended up claiming the Lapwing, as the Peregrine did eventually land some way off from the point where the Lapwing came down.
