Recently sparrows returns to my garden. So I invested in new bird feeders for the front and back, and Chris gave me some special bird seed. The sparrows came back - but then Mr or Mrs Squirrel spotted the chance for some free food. Not only did he (she) take the seed, but he (she) knocked the feeder off the bird table and very nearly smashed it - twice. I have foiled him (her) now - but wiring the feeder onto the table so that he (she) will not be able to take it down. That will teach him (her)!
Watch this space! The sparrows have not returned - yet . . .
