SIR - Regarding Peter Alcock's mind-bending thought on an ice-free drinking receptacle for birds, I have a more simple way Peter - a pond, a pump, a rockery and a three tier waterfall.

Because the pump is never switched off, our birds can drink and bathe 365 days of the year.

And with 30 nest boxes around the garden, their numbers are always plentiful whatever time of the year.

Even our nocturnal friends the badgers take advantage of the drinking facility.

You are most welcome to call on us at any time to see the set-up in operation, Peter.

JOHN EVANS, Kempsey, Worcester
