Hummingbirds are small birds that belong to the Trochilidae family and are native only to the Americas. They are known for their ability to hover in mid-air. Different cultures have different myths about humming birds. It is said that they bring joy and happiness to the person who encounters them.
Were you wearing red? Maybe perfume? Bright colors? My friend has a tree where they like to hang out and they all fight over the feeder.. It's sooooo funny to watch them divebomb each other- like little dogfighters airplanes. They are VERY territorial! For whatever reason they come to you- enjoy them- they're cool!
I read that hummingbirds are very territorial and aggressive, so it may be it was just inspecting you and telling you to "look out!" you're in his territory.
Could be a number of things. If its a more domesticated hummingbird (comes around often for nectar and other foods) it could have realized you are the source and was waiting for nourishment, if it was territorial, it could have been a warning. It could also have been out of plain curiosity, as many animals will stop to stare at things a small while if they do not understand it
We notice that the humming birds hover in front of us when the feeder is empty. Either when we are sitting on the deck or they just come to the window or patio door. It's like they are begging for more sugar water.
It means a hummingbird got close to you, that's it, that's all, nothing more to say!
