Cor! Luv a duck – goose shocks Trust

Staff at Slimbridge Wildfowl and Wetlands Trust, in Gloucestershire, are stunned by the bizarre courtship between the bar-headed goose and the dainty mallard duck.

With breeding season getting into full swing the couple are raising eyebrows on a lake right next to the visitors centre.

Wardens say the goose "is doing everything in his power to woo her" and is fiercely chasing off other geese or ducks who come close.

There is even an "extremely unlikely" chance the pair will produce hybrid offspring.

Slimbridge Reserve warden, James Lees said: "I'm not sure whether he thinks he is a mallard or whether he thinks she is a bar-headed goose, but I guess they do say love is blind."
