Happy New Year! Indeed, the hummingbirds’ prismy feather features are amazing. You inspired me to look up this feature and I found this great quote:

“In many species, the coloring does not come from pigmentation in the feather structure, but instead from prism-like cells within the top layers of the feathers. When light hits these cells, it is split into wavelengths that reflect to the observer in varying degrees of intensity. The Hummingbird feather structure acts as a diffraction grating. The result is that, merely by shifting position, a muted-looking bird will suddenly become fiery red or vivid green.

However, not all hummingbird colors are due to the prism feather structure. The rusty browns of Allen’s and Rufous Hummingbirds come from pigmentation. Iridescent hummingbird colors actually result from a combination of refraction and pigmentation, since the diffraction structures themselves are made of melanin, a pigment.”

Thank you, Mimi!

Reading “Where the Crawdad Sings” and learned fun fact that hummingbird breast feathers have microscopic kaleidoscopes creating wonderful shimmering effects. Best wishes, Mimi

Many times I’ve seen crows perch together on the tallest building around before swooping to their destination. They are pretty great to hear out of nowhere.

It’s impossible to know for sure but I agree with you that Juno seems like a young adult.

Thank you so much for your kind words, Jeanne!

I do see crows flying and calling out, but no dynamic flights w/ one dive bombing as your first picture shows…
that’s something…I would have thought it was a hawk.
How old do you guesstimate Juno to be at present?
In his pictures , to me , not a hawker, he appears as if an early adult?
Hope your Holidays continue to be good to you , Roger_Paw…you have created such a wonderful place to come to at days end to see the lively adventures of our dear, precious hawks…Thank you.
