Fun things to do and great places to discover nature.
The eastern red bat spends its summer days hanging by one foot from a tree limb, looking a lot like a dead leaf. At dusk, it flits off to hunt for flying insects. It has small eyes, but it relies on echolocation to “read” its environment. It emits high-frequency sounds that bounce off prey and back into its big ears. The echo pattern tells the bat what to attack and what to avoid.
How do beavers know when their dam has sprung a leak? Biologists believe it’s the sound of running water that sends the buck-toothed builders into a fix-it frenzy. To test this idea, researchers left a small speaker on top of a leak-free dam. All through the night, the speaker played the sound of gurgling water. When the researchers returned the next morning, they found that beavers had buried the speaker under a thick layer of sticks and mud.
The only completely red bird to visit Missouri, summer tanagers fly from South America to spend the breeding season in
North America. Summer tanagers mainly feed on bees and wasps, somehow without getting stung! What’s this male tanager
doing with a soft, squishy caterpillar in its beak? Most likely carrying it back to his nest of youngsters. It takes thousands of
caterpillars and other soft-bodied insects to raise a brood of baby tanagers.
