What sound does a butterfly make? With it’s delicate wings, not a whole lot–until you get millions of them together in one place. Most monarchs migrate to Mexico for the winter. There, they huddle in trees at night and flit
Slingshot spider
You thought cheetahs were fast? Meet the slingshot spider. This resident of the Peruvian rainforest nabs a meal in its web like most spiders. But instead of waiting for the food to come to it, this spider takes its web
Ninja kangaroo rats!
Nature is awesome, and so are the scientists who study it. Researchers studying rattlesnakes and kangaroo rats (common predator and prey) needed to be able to see what happened during those lightning-quick interactions. To do so, they used high-speed video,
I have a book in the Scholastic Book Fair!

Alison’s Adventures: Close encounters of the reptilian kind
I had a close encounter with (captive) wildlife not long ago, when my family visited the Wild Discovery Room at the Crane Festival in Kearney, NE. There were all kinds of great critters there, including eight or nine raptors (owls,
Drones to the rescue
Researchers in Switzerland have created a “smart” drone (unmanned aircraft) that can follow a forest trail–all by itself. The drones use a camera to “see” what lies ahead. The scientists used a deep neural network to program the flying bot.
Scientists discover deep-water octopod
Given how much of the world people have explored, you would think that scientists had discovered all the species out there. But new discoveries continue to happen. Take this “remarkable little octopod” discovered at 5,000 feet below sea level —
Death Valley in full bloom
Death Valley is one of the hottest places on the planet, and most of the time, it’s sandy and barren. But when rain falls, all that changes. Seeds that lay hidden in the soil (sometimes for years) burst open and
