What happens in a marsh harrier food-pass?

Crick-necked and open-mouthed, you’ll never forget your first marsh harrier food-pass. High over the reedbed, two dots soar in the April sunshine. They circle each other, then suddenly the upper bird, a male, drops his prey.

The food is ‘fielded’ deftly by the female below him, who performs a mid-air roll to seize it in her talons. This display is accompanied by sky-dancing – dramatic twisting plunges and slow-motion flapping.
