While pretty to look at, the hummingbird feeder is not too functional - a reservoir you can’t see / see into, and only holds 8 ounces - which would feed 4 birds for a day.
And while I don’t have this one so I can’t speak with certainty - I’ve yet to see one with a design like this that didn’t dribble itself empty.
Buy it for looks, don’t buy it for feeding hummingbirds. The $7 plastic jobs from Wal*Mart will do a much better job of actual feeding.
