From Howard Frost
My wife and I looked after two gulls with incurably broken wings for 16 years. We usually fed them relatively expensive cat food, but once I threw them a cheap brand.
The gulls dashed towards it, then stopped 2 metres away and went to the back of the garden. At the time we were puzzled, as they had not even tasted the food.
Thanks to Birkhead, I now realise they probably detected the awful odour, just as we did.
