Nice shot, except that I wish you had cropped it tighter, to see the bird better.
FYI........ You really shouldn't use the red stuff to feed them. Mix it at home, with a 4 to 1 mix (4 parts water, and 1 part table sugar). Heat the water, add sugar and stir (dissolves easier and better in hot water). Let it cool, and serve. They love it! Do an online search for hummingbirds and read up on them. The red stuff can be harmful to them. Here's a site to get started with: World of Hummingbirds .com
Did you know it's a federal offense to possess a hummingbird feather, and especially the bird? It's because they are a migratory bird.
It is cropped about as close as the image will hold up, it was shot from about 50 yards away with a 70-300mm@300mm f/5.6. Not my bird feeder, my neighbors.
