When my parents were here I actually saw some hummingbirds out front. I decided to get a new hummingbird feeder. The old one is hard to clean and has gotten kind of gross. I got this one at Home Depot. It is glass and mostly metal (with some plastic.) The only reason I put in the red liquid is because it came free with the feeder. Normally I just dissolve sugar in water. The red dye might actually be bad for the birds and it isn't necessary to attract them. I have yet to see a hummingbird feeding from it, but I haven't really been watching.
