Sometimes in the shit-storm of bullshit that so overwhelms us, we just need to stop and look at the world. Given that it’s February and all the roses are imported from horror-stricken farms where the workers are brutalized and doused with toxic chemicals and then the roses themselves are stripped of their thorns — what the fuck is a rose without thorns? — it sure and hell is not a case of stopping to smell the roses. Come back in May and June for that, but remember that many varieties of even the live ones have be de-odored by their Dr. Frankensteins.
Instead, I offer you the speculum of an American Black Duck (Anas rubripes) beading a drop of water. And only a mere simulacrum of one, at that, an arraignment of digital data, a window of a window, but one that should still do something to set your hearts a-racing. How anyone could ever go back to the television again after seeing one of these with one’s own two eyeballs is beyond my understanding.

Feathers are colored in two ways or in a combination of these two ways: with pigments, or, as here, structurally. The duck’s speculum (the word means “window,” ladies) refracts the light striking it. The microscopic design of the feathers act as prism to broadcast what we read as iridescence. Structural color isn’t always iridescent, however: the blues, as in the Blue Jays, are structural not pigment.
And now consider what this must look like to another bird: birds can see ultra-violets that we can not because they have four cones to our three.
