It is fascinatng that males and females in some species of birds share the responsibility of raising the young, but not hummingbirds. They seem more terratorial than most other birds. The expandable nests are cool!

I have learned so much! The explanation of their iridescence - melanosome of different thickness within barbules was astounding. The fact that their tongues wrap around their brains and how they get the nectar inside their tongues was new to me. I hope the course will explain how they feed during migration, and what do they feed their chicks - nectar or insects or both? Great course!
