A FEW weeks ago there was an article in the Evening Press about the strange behaviour of birds after eating rowan berries (August 9).

I do not know if you have received an explanation.

The information I have is that rowan berries can be made into jelly and wine and contain vitamin C. So if the birds eat too many they have really had too much wine.
