This is something I have never heard of or seen before. This woman lives in a Hummingbird fly zone. As they migrated, about 20 of them showed up in her yard. She took a little piece of reddish, filled it with sugar water and lo: This is the result.
The lady mentioned here is Abagail Alfano of Pine, Louisiana. She had been studying them daily and one morning put the cup from the feeder (with water in it) into her hand. Since then they had got used to her standing by the feeder and without fear, they would fly over to feed directly from her hand.
Many thanks to Ron Lim for sharing.
