Beaver's lodge and dam
◐ About Beavers ◑
Body- parts(신체구조)
The beaver is a large, web-footed, semi-aquatic rodent with brown fur and a wide, flat, dark tail.
The tail acts as a rudder while swimming,
as a prop for standing upright,
as a lever when dragging tree logs,
and as a noise maker for producing a warning signal when it is slapped on the water.

수영하는 동안, 곧게 서있는 동안, 통나무를 끌 때, 적이 나타났다는 경고음을 낼 때도 사용하기도 합니다.
The fingers have long claws, and the legs have webbed feet and claws.
-->손과 발에는 날카로운 발톱이 달렸으며, 발가락은 물갈퀴가 있습니다.
The beaver has a large, wide, head. It has sharp, renewable, self-sharpening, enameled teeth that can cut through wood and fell a tree. -->머리는 크고, 날카롭고 큰 이는 나무를 갉아 넘어 뜨릴때 사용하고 다시 자란답니다.
The adult beaver weighs about 20 kg (44 pounds), but can be as large as 35 kg (77 pounds). It is about 30 cm (12 in) tall, and its tail is about 25 cm (about 10 in) long. The beaver is the largest rodent in North America. Its life span in the wild is about 20 years.

HABITAT(서식지)
<--A4크기로 출력하여 사용하세요.
Beavers live in North America, Europe, and northern
Asia, and are famous for their building skills.
Beavers live by rivers, streams, ponds, and lakes.
They are one of the few animals that alter their environment in a large-scale way in order to provide themselves living space and protection.
-->비버는 스스로를 보호하고 삶의 공간마련을 위해 그들의 환경을 개조하여 살아간다고 합니다.
Beavers build dams that change the course of streams and create ponds.
They build dams and lodges using sticks, bark (from deciduous trees), mud, and logs (that they fell themselves).
The presence of pointed tree stumps is a good indication that there are beavers living nearby.
-->나무그루터기의 존재는 비버들이 근처에 살고 있다는 좋은 표시이지요.
To create a habitat, beavers build a dam in a stream, flooding an area of the woods and creating a pond in which the beaver can build a lodge.
-->서식지를 만들기 위해, 비버는 숲의 범람지역의 강줄기에 댐을 만들고 호수에 굴을 짓습니다.
This beaver lodge or den is located away from shore and has an underwater entrance.
-->비버의 굴은 강변에서 떨어져 있고 입구도 물 아랫쪽에 있습니다.
This makes it difficult for most predators to enter the lodge.
-->포식자들이 굴 입구로 들어오기 어렵게 만들지요.
In winter, the water around the lodge usually freezes, protecting the beaver almost completely.
-->겨울에 보통 lodge주변의 물이 얼면 비버들은 완벽하게 보호 받게 되는 것이지요.
Each beaver pond is inhabited by one beaver family: two adults and usually 2-4 kits (very young beavers) .
-->각 비버연못에는 한 가족씩 서식한답니다. 어른 둘에 아주 어린 새끼2~4마리정도.
When the food supply around the beaver's home is exhausted, they move to another site and start again.
--> 집 주변의 먹이가 고갈되면 다른 장소로 옮겨 간 답니다.
REPRODUCTION (번식)
Beaver mating occurs in January or February.
The kits are born in early spring, from April through June.
When young beavers reach their second summer, they take on adult duties, building and maintaining the lodge and the dams.
They reach adulthood during their second winter and move away to find a mate and build a lodge of their own.
FOOD(비버가 먹는 음식들)
The beaver eats aquatic plants(수중식물) (including pond weeds, water-lilies, and cattails)
and the cambium(형성층,식물 줄기나 뿌리에 있는 조직) (the soft tissue in which new wood and bark grow) of hardwood trees, including birch(박달나무), aspen(미루나무), willow, cottonwood, and alder.

PREDATORS(비버를 포식하는 동물들)
Some of the animals that prey upon beavers include foxes, coyotes, wolves, lynx, otters, weasels, hawks, eagles and owls.

Rodents are relatively small, prolific mammals.
All rodents have a pair of front teeth that continue to grow throughout their lives; they must gnaw on food (or other objects) to grind these teeth down.
Most rodents are herbivores (plant-eaters). Some rodents, like the house mouse, are omnivores (eating plants and animals). A few rodents, like the Australian water rat, are carnivores (meat-eaters)
