Hummingbird's Nest

I found this the other day--I think the babies were out of it before the wind knocked it down--I hope so. Click on the picture to see this up close--there's lichen, white fluff from what?, little feathers, bits of eucalyptus bark, and other very small things. The nest is very soft and I imagine the eggs were tucked in under the edges?

Ernst Haeckel, born in 1834, a German biologist, naturalist, philosopher, physician, professor and artist, created these beautiful illustrations in his book, Artforms of Nature (1904)
With all those titles, he should have drawn out a page full of hats--all kinds of hats!
