Get cozy for this week’s Ask Your Weird Animal Questions, because it’s all about nesting.
“In [Michigan] where I live we have the ruby-throated hummingbird. They use spider webs to make their nests. Does anyone know if they use the webs of specific spiders, or if the spiders travel with them to the nests?”—Ventura Calederon Parada, via a comment on “A Living Nest?”
Hummingbirds make these intricate nests with a base of thistle and dandelion, and then build the walls by lacing spiderweb with plant matter using a figure-eight motion.

“Although the reader’s idea is ingenious, it doesn’t really seem plausible,” James V. Remsen, Jr., curator of birds at Louisiana State University in Baton Rouge, said via email.
For one, it’s not known whether the birds prefer the webs of a specific type of spider.
What’s more, any spider that gets accidentally picked up by a hummingbird would likely end up being a meal, he said. In addition to feeding on nectar, “hummingbirds are voracious insectivores,” he said.
“Can you tell me why a wild rabbit would dig a hole about [half] as long as it is, store dead oleander leaves in it, and then cover it up completely? Even spreading the decorative rocks back where they were originally… Even though we knew right where it was done, we couldn’t see any trace of disturbance.”—Bernice Spurger, Quartzite, Arizona
This enterprising rabbit is likely a mother making a nest.
“Female rabbits often dig a small burrow and line it with leaves and twigs,” Anthony Knight, retired professor of clinical sciences at Colorado State University in Fort Collins, said via email. “I have observed this myself in the past, but not with oleander leaves.”
Pinau Merlin, an Arizona naturalist, lecturer, and author, said in an email, “Even when the babies are in the nest, the mother covers it over again so it is invisible to predators.” She returns twice a night to nurse her young, Merlin said.
“This may be a young, inexperienced rabbit if she is using oleander leaves,” Merlin said: Oleander is toxic if ingested. Knight added that oleander may have just been in abundance at the time that the rabbit in question made her nest.
“Never seen a crow [nest]. Do they fly [south] for the winter?”—Ninas Cherry, Illinois
According to the Cornell Lab of Ornithology, crows usually hide their nests “in a crotch near the trunk of a tree” or in the upper two-thirds of a tree. Anywhere from 6 to 19 inches (15 to 22 centimeters) in diameter, crow nests are made mostly of medium-size twigs and lined with pine needles, weeds, soft bark, or animal hair. They have a clutch of six to nine eggs. Some crow species migrate, while others stay put.
One last nest you have to see is this hornet’s nest that looks as though it’s grown out of a human face. The photo was posted on Reddit by Cliff Seeger, whose dad made the wooden face sculpture about ten years ago, the Huffington Post reported. It had been in an unopened shed for some time—long enough for the hornets to make an entire resort out of it.
Hornet’s nests, according to Michael F. Potter at the University of Kentucky, are usually attached to a tree, bush, or building; “resemble a large, inverted tear-drop-shaped ball”; and should be removed only by a pest-control professional.
