We had a clear plastic 2-foot tall tubular bird feeder hanging in our yard for a couple of years, until a squirrel decided he liked the clear plastic better than the food.
I have built a similar hanging feeder from a section of 2" PVC pipe. The b ottom is capped, the top is a threaded fitting to be opened to put in the b irdseed. I drilled holes in the sides and mounted the plastic opening inse rts from the old feeder into the new feeder.
One bird has figured out that the new feeder is ok. but most of the birds s eem to be staying away. The PVC pipe is the usual off-white color. I am w ondering if there is a better color to paint the tubing that would be more attractive to the bird population. Suggestions --------
