How young com辦zrs (美洲獅) leam to hunt is one of the things cougar researchers like Mark Elbroch are working hard to figure out. “We know nothing about their secret lives' Elbroch says. He and his team track cougars deep in the Wyoming wilderness.
An adult called F51 was one of the cougars they kept (標(biāo)簽) on —they followed her using the satellite signal from her electronic collar. One fall when Elbroch discovered that F51 had given birth to four kittens — three females and a male —he put expandable tracking collars on them too,so he could follow them as they grew.
About one week after they were bom,their eyes opened. Their fur was thick enough to blanket them from the oncoming cold winter. Their brown and black spots could mix with the forest,helping to keep them safe from (食肉動(dòng)物) .
By the time they were five weeks old the four kittens were restless to leave their home. They'd still be nursed for another month,but they were ready to go out of their hideaway with their mother. They began to learn their way around Mom's territory(領(lǐng)地). As they grew older and stronger,they learned how to search for food by following their mother,watching her select an animal to approach,and observing how she caught the animal.
While they were only a few weeks old,Mom would tell her kittens to hide when she hunted. Sometimes she has to travel a couple of miles to find'meal. “The minute she makes the kill,she hides it and heads back for the kittens,and they follow her to the kill site,” Elbroch says.
But the kittens learned that sometimes meal plans change quickly. In February and March,wolves chased F51 and her kittens away from six different kills. During the cold winter,one kitten disappeared” probably a victim of wolves,and another didn,t survive the bitterly cold weather.
Luckily F51 was able to provide plenty of food for her two remaining kittens. She shares her territory with another female,and they are friendly with each other. F5Ts kittens have learned that cooperation is a choice. “We have seen females get together and share food”’Elbroch says. “F51 spent three or four months sharing almost every kill with an unrelated female and her kittens."
