Nature sometimes seems cruel to us, but we have to accept that even jays need to be fed. We were out walking and we met an old lady who was watching some cats playing in a yard. She told us that one of them was a nice cat, but the other one was cruel, because it was chasing and killing birds and squirrels!
But I admit I get annoyed when the suet balls I have been offering the tits and sparrows are gobbled up in five minutes by the magpies. We finally found some perfect feeders which have room for 3-5 suet balls, they have an extra wide-meshed ball on the outside which allows the smaller birds, and the birds love them. The photo is not very good, it was taken from an upstairs window (as you can see, it's been snowing).
