red squirrel or Eurasian red squirrel

Description:

The red squirrel has a typical head-and-body length of 19 to 23 cm (7.5 to 9 in), a tail length of 15 to 20 cm (5.9 to 7.9 in) and a mass of 250 to 340 g (8.8 to 12 oz). It is not sexually dimorphic, as males and females are the same size. The red squirrel is somewhat smaller than the eastern grey squirrel which has a head-and-body length of 25 to 30 cm (9.5 to 12 in) and weighs between 400 and 800 g (14 oz to 1.8 lb). It is thought that the long tail helps the squirrel to balance and steer when jumping from tree to tree and running along branches and may keep the animal warm during sleep

Habitat:

The red squirrel or Eurasian red squirrel (Sciurus vulgaris) is a species of tree squirrel in the genus Sciurus common throughout Eurasia. The red squirrel is an arboreal, omnivorous rodent. --In Great Britain and Ireland, numbers have decreased drastically in recent years, in part because of the introduction of the eastern grey squirrel (Sciurus carolinensis) from North America

Notes:

i heard something, while taking shots from a mushroom. 3-4 meter further was this little guy, jumping over the ground. While i was standing up to sneak on him, he noticed me and was jumping on a tree (in no time). there he observed me, and climbed only further, when i was moving. He also theaten me, (picture 3 - better to see in the link from wikipedia, direct the first picture on the right- that's the pose) he lifted/raised his bushy tail and began to drum/punch on the bark of the tree. it was defense/intimidation behavior
