These guys don't pack heat... yet! They still handle things with beaks and body slams al la WWF. I tried equipping one with a pylon mounted 17 Remington Fireball; we still haven't found the bird. The bullet fell and the bird went backwards at 4000 fps; back to the drawing boards.
I love watching them do that. I still dont get why I only seem to have one or two hummers this year. I saw the male yesterday in the flower beds. He went to the feeder as well, but then was gone and not seen again. Odd.
To attract every bird in the area start with a 50/50(1:1) blend of sugar water. Once you get the birds, gradually reduce the concentration to ~3:1. Hummingbirds will go to the sweetest feeder. Your neighbors will use 4:1; I don't share my birds. Change you solution often and do not clean the feeder with dish detergent. Use a bleach solution and rinse it well.see attached<[link]>.

They are the real colors w/o iridescence from the flash. If I do use flash I use a diffusion cover with one or two tissues stuffed into it. The Canon 100 mm L is very nice, my old Nikon 105 sounds like a diesel starting up and scares the birds.
