at previous property, we had trees spaced nicely apart.
put in some eye-hooks, used 14 gauge bare copper wire, to suspend bird feeders 10-15 feet out from the tree trunks.
neat idea - but the squirrels would wire-walk the copper, then scoot down the hang wire, and feast . . .
I have a ‘cone’ arrangement on a ‘shepherd hook’ hanger that actually works quite well - except the ‘cone’ tends to slip down the hanger ‘vertical’ which allows them to ‘leapt’ past the cone baffle… need to devise a way to keep the cone baffle at its proper ‘height’ . . .
not a difficult thing, just need to ‘do it’
