Here, in today's NY Times, is an interesting comparison between hummingbirds and bees. However, it does not mention aggression between the 2 species (with bees usually winning), or the fact that bees make holes in flowers which prevent hummers from feeding (see https://www.ucdavis.edu/news/hummingbirds-avoid-nectar-robbed-flowers/).

All the flowers at the sanctuary are long gone, and I'll soon be reporting "Calypso", from our winter location in the Bahamas. It will be good to see hummers again - and this view!
