The blink of a hummingbird's eye...

caught in a pair of images, capturing the moment when the nictitating membrane extends across the eye.

Black-chinned Hummingbird (Archilochus alexandri).

The opaque nictitating membrane extended across the eye, for about 1/60th of a second.

The first hummingbirds...

arrived yesterday and they’re already zooming the feeders. This one is taking a rest after doing the aerial sexy dance for a while, displaying for a female at one of the feeders.
