Possible?

I googled some stuff about hummingbird and sunbird. It seems hummingbird doesn't exist in Singapore but in western countries. The thing is I still think it is a hummingbird because it is hovering over the wind chimes hanging like a curtain from the ceiling and able to stay like that for quite some times. It was then zig zagging here and there at a very fast speed. Their flaps are fast and furious. Sunbird has to perch while feeding. The most mesmerizing thing is to see it hovering. It stayed in that position which furiously flapping it's wing that it looks like it was very very fast that it looked very still. Can somebody prove me right? well, I don't care. It must be a hummingbird. I have never seen a sunbird though. What I found online is that it has a curved beak and it couldn't hover and feed like hummingbird.
