dear gardening fanatic - your pictures are excellent, thank you. Is the green tubing made of plasti or metal If plastic, the squirrels will have bitten through it in the first couple of days, and will have lifted the roof before I get the back door closed, I have to wire everything on to the feeders. I don't object to many birds, but magpies and pigeons I'm afraid are off my radar altogether, the damage they do is quite extraordinary. I do have different types of feeders around, it is just this one with the fat balls (which aren't balls at all, but narrow tubes as I set the mixture in small plastic drinks bottles - that size just fits the peanut feeder) has become impossible, being completely cleared byt he squirrels and magpies in about 10 minutes - and I cannot keep that rate of feeding up with the best will in the world - and as far as squirrels and pigeons are concerned, let alone magpies, I don't have the best will in the world. I know these caged feeders are sold everywhere, so they must be used, just not by my birds. They are using all the others that the magpies and pigeons cannot perch on - yet. The squirrel gets on there and just sucks the seed down like a small vaccuum cleaner - you can literally see it falling down the tube, at a kilo at a time, that is beyond me too - hence I want the small birds to use the caged feeder - maybe when they get hungry enough in poorer weather they might.
