Barbara found this Ruby-throated hummingbird nest on the ground in the Azalea Collection

Hummingbird nests are cool. they're woven of fine plant fibers, sometimes with moss, lined with spider webs and plant down (Joan found Sycamore "lint"), and the outside is covered with lichens.

I remember trying unsuccessfully, many years ago, to photograph a nest that I canoed up to on the C and O Canal. The nest was about the level of my head and the sitting hummer didn't spook at my aqueous approach, but I was unable to hold the canoe steady and take the picture. Very frustrating.
