Sounds like you've got a great setup there :) My parents have a lot of feeders and I love to just watch them do there thing when I visit. I can stand a couple of feet from the hummingbird feeder and they'll swoop on in and feed, I just have to remain still and they don't seem to mind :)

Chickadees are quite the friendly birds! Just holding my hand up to block the sun and they'll land and look for some food :) The red-winged black birds do the same! They're spoilt here in Stanley Park :)
