Barn owls and a marsh harrier (distant), but no hen harriers

Yesterday I joined the RPS raptor followers in the Boardwalk Hide at Wicken Fen in the hope of seeing the hen harriers coming in to roost; Sadly we saw no hen harriers which would have been a treat, but we caught a couple of barn owls in the fading light and a very distant marsh harrier (Oh, and a sedge head whist I was waiting!)
