Attenborough covered same evolution for other type of hummers m.youtube.com/watch?v=yc8o...
Lesson learned…humans are having an impact on species. Sadly, it’s what we don’t see or is subtle that could have greater impacts. Pollinators are but one example, and there would be no hummingbird species without co-evolution with pollinators. Soil biota are another example we don think much about.
I have a feeder & it should be studied how they’ve adapted to communicate with humans. The hummingbirds in my neighborhood will fly up to my window & hover to tell me when I need to refill the feeder if I’m busy or happen to forget. They make their loud little squeaks when I refill it too, it’s cute
