Hummingbirds appear to have eyelids. Why wouldn't they have eyelids, you ask. It's noticing them that's hard.

Anna's Hummingbird

Thinner and more transparent than the fleshier upper and lower eyelids we’re all familiar with, the nictitating membrane allows some degree of visibility while simultaneously protecting the eye. The bills (and therefore the heads) of birds are vulnerable during foraging, flight, excavating, and diving, while feeding young, and gathering material for nests, etc., so extra eye protection is quite valuable.

The nictitating membrane is widespread in nearly all the vertebrates, including fish, amphibians, reptiles (which include birds), and mammals. In humans and other primates, they exist only as a vestigial structure.

I didn’t know until a couple of years ago that hummingbirds eat insects. I saw a video of one flying and catching an insect.

7. Having a composting area with fruit peelings in the gardens helps provide them with lots of gnats :)

We really only get them in fall and spring during their migration. We always put up our feeder and enjoy them .
