Hi Nic, yes that is a feeder I made some years ago with plant pot saucers. Has a threaded bar so I can lower the roof to deter cats. I have wooden box feeders as well. But in the winter I can use that feeder for blackbird food.
Plastic is getting brittle now, so during hibernation I will make another one. Will be good for several years. I reckon that one is 5 years plus old.
