I have so many hummingbirds in my yard and they LOVE this feeder. The little perch provided with it is great! My hummingbirds sit on it and take a break from fluttering! They all flock to this feeder. The picture shows red liquid, but there is no need to use anything but sugar water. I have never added anything to make my nectar red and the birds have no problem finding it.  The size is great, I have to refill it much less than the other feeders it replaced! Highly recommended!!
