SvenskaThe animals of Lake Sidsjön
Six animals live around the lake. Here you can find out how big they are, what they eat, the tracks they leave and how they sound — written so children can read it themselves.
Red squirrel
Sciurus vulgaris
A squirrel can jump six metres from tree to tree.
Red fox
Vulpes vulpes
A fox can hear a vole digging under the snow.
Buff-tailed bumblebee
Bombus terrestris
A bumblebee can shiver herself warm enough to fly in the cold.
Common frog
Rana temporaria
A frog can jump twenty times its own length.
Mallard
Anas platyrhynchos
A mallard's feet cannot freeze — the blood warms itself on the way back.
Perch
Perca fluviatilis
The perch has spines on its back fin — that is why few animals eat it.
