Wait is that your actual photo? I thought it was a stock shot. It is great. What settings and what camera did you shoot it with.
I've never set up a feeder but I have had red flowers in my deck boxes that draw them right in. They are fun to watch.
Was probably a suet sandwich feeder. The suet is placed between two pieces of bark wood. - Woodpeckers can reach between the boards to get the suet. Birds without long tongues can't reach it.By the way - went out to dinner at a new (to us) bar / restaurant and they had 10 - 20 hummingbird feeders and a couple of regular bird feeders (and one I don't know what it was supposed to feed, a woodpecker?, it looked like it was filled with wood).
Only saw a few hummingbirds but a bunch of more common birds were at the regular feeder.
