I live in Phoenix where it's so hot in the summer (110 to 115) and my plastic feeder cracked after three years. So I bought a new one yesterday that's clear glass. And the hummers are not coming back.
My plastic one was red. I don't use food coloring, just natural sugar water I make. The new one has a red base for sitting on and sipping nectar.
Any suggestions? Should I paint the feeder red with glass paint to bring my little friends back?
