I’ve been watching hummingbirds at our feeder, and took a moment to read up on them a bit more. Hummingbirds.net has a lot of interesting information, including about their impossible migrations. (These migrations are proved by the Internet and reported by people like you and me.)
But what really amused me was this straightforward and presumably accurate description of their nests:
The walnut-sized nest, built by the female, is constructed on a foundation of bud scales attached to a tree limb with spider silk; lichens camouflage the outside, and the inside is lined with dandelion, cattail, or thistle down.
Undoubtedly tended by singing dragonflies that feed on unicorn tears.
