Day 11, post-hatching, the largest of the hummers has opened its eyes, and its beak has turned black.  It did not exhibit a feeding response but also didn’t seem too concerned that I was taking photos.  The smaller sibling remained curled up but is breathing.  I’m hoping to see the color of its beak and whether or not its eye has opened.  Both babies peep.

Mom only buzzed by once to find out what was happening.  She now lets me observe her after dark, when she is sitting on the nest, but I don’t want to frighten her with a flash.

I read that hummingbirds use spider webs to hold their nests together and to anchor them to branches.  The fuzzy understructure of this nest looks suspiciously like the BFF’s golden fur.

By the way, the photo is slightly tilted, not the nest.
