Most people agree that honesty is a good thing. But does Mother Nature agree? Animals can’t talk, but can they lie in other ways? Can they lie with their bodies and behavior?
Animal experts may not call it lying, but they do agree that many animals, from birds to chimpanzees, behave dishonestly to fool other animals. Why? Dishonesty often helps them survive.
Many kinds of birds are very successful at fooling other animals. For example, a bird called the plover sometimes pretends to be hurt in order to protect its young. When a predator (猎食动物) gets close to its nest, the plover leads the predator away from the nest. How? It pretends to have a broken wing. The predator follows the “hurt” adult, leaving the baby birds safe in the nest.
Another kind of bird, the scrub jay, buries its food so it always has something to eat. Scrub jays are also thieves. They watch where others bury their food and steal it. But clever scrub jays seem to know when a thief is watching them. So they go back later, unbury the food, and bury it again somewhere else.
Birds called cuckoos have found a way to have babies without doing much work. How? They don’t make nests. Instead, they get into other birds’ nests secretly. Then they lay their eggs and fly away. When the baby birds come out, their adoptive parents feed them.
Chimpanzees, or chimps, can also be sneaky. After a fight, the losing chimp will give its hand to the other. When the winning chimp puts out its hand, too, the chimps are friendly again. But an animal expert once saw a losing chimp take the winner’s hand and start fighting again.
Chimps are sneaky in other ways, too. When chimps find food that they love, such as bananas, it is natural for them to cry out. Then other chimps come running. But some clever chimps learn to cry very softly when they find food. That way, other chimps don’t hear them, and they don’t need to share their food.
As children, many of us learn the saying "You can't fool Mother Nature." But maybe you can't trust her, either.

My wife Laura and I were on the beach, with three of our children, taking pictures of shore birds near our home in Alaska when we spotted a bear. The bear was thin and small, moving aimlessly.
Just a few minutes later, I heard my daughter shouting, “Dad! The bear is right behind us!” An aggressive bear will usually rush forward to frighten away its enemy but would suddenly stop at the last minute. This one was silent and its ears pinned back— the sign (迹象) of an animal that is going in for the kill. And it was a cold April day. The bear behaved abnormally, probably because of hunger.
I held my camera tripod (三脚架) in both hands to form a barrier as the bear rushed into me. Its huge head was level with my chest and shoulders, and the tripod stuck across its mouth. It bit down and I found myself supporting its weight. I knew I would not be able to hold it for long.
Even so, this was a fight I had to win: I was all that stood between the bear and my family, who would stand little chance of running faster than a brown bear.
The bear hit at the camera, cutting it off the tripod. I raised my left arm to protect my face; the beast held tightly on the tripod and pressed it into my side. My arm could not move, and I sensed that my bones were going to break.
Drawing back my free hand, I struck the bear as hard as I could for five to six times. The bear opened its mouth and I grasped its fur, trying to push it away. I was actually wrestling (扭打) with the bear at this point. Then, as suddenly as it had begun, the fight ended. The bear moved back toward the forest, before returning for another attack— the first time I felt panic.
Apparently satisfied that we caused no further threat, the bear moved off, destroying a fence as it went. My arm was injured, but the outcome for us could hardly have been better. I’m proud that my family remained clear-headed when panic could have led to a very different outcome.

Discover Nature Schools programs
Becoming Bears (Kindergarten-2 grade)
By becoming baby bears, children learn from their “parent” to survive the seasons. Kids will find safety in the spring and learn kinds of food bears eat during the summer, and then create a cave for winter hibernation(冬眠). After learning the skills needed to survive, students will go out of the cave as an independent black bear able to care for themselves. (1.5-2 hours)
Whose Clues? (3-5 grade)
Kids will discover how plants and animals use their special structures to survive. Through outdoor study of plants and animals, kids will recognize their special structures and learn how they enable species to eat, avoid their enemies and survive. Using what they have learned, kids will choose one species and tell how they survive in their living places. (3-4 hours)
Winged Wonders (3-5 grade)
Birds add color and sound to our world and play an important ecological (生态的) role. Students will learn the basics of birds, understand the role birds play in food chains and go bird watching using field guides and telescopes. Students will do hands-on activities. Students will use tools to build bird feeders, allowing them to attract birds at home.(3-4 hours)
Exploring Your Watershed (6-8 grade)
We all depend on clean water. Examining how our actions shape the waterways around us. Go on a hike to see first-hand some of the challenging water quality problems in a city. Students will test the water quality to determine the health of an ecosystem.
● Each program is taught for a class with at least 10 students.
