communities and a number may live together in a 

 hollow tree. However, each pair usually stores up 

 their own winter supply of food which is concealed in 

 another tree from the one in which the nest is placed. 

 There are usually from three to seven young. 



The flying sq^uirrel is a nocturnal animal and it 

 possesses large glowing eyes. It is omnivorous and eats 

 nuts, insects and birds' eggs. There is also some evi- 

 dence to indicate that it will, occasionally, eat young 

 birds. The animal is easily tamed and makes an excel- 

 lent pet, but it avoids bright light, and will crawl 

 under one's coat or into his pocket to avoid it. A full 

 grown animal may attain a length of 10 or 12 inches. 

 The males and females are alike and there is little 

 seasonal variation. 



Beaver 



Castor canadensis 



The beaver is one of the rarest and most interest- 

 ing of our native mammals. Its spectacular habits 

 reveal some remarkable adaptations. It is a swimmer, 

 woodsman and engineer. 



The hind feet are webbed for swimming and the 

 long, broad, flattened tail is used as a rudder. The 

 great incisors, characteristic of the rodents, serve ad- 

 mirably in felling trees, and the endurable homes and 

 dams show a practical knowledge of construction on 

 the part of the animal. 



The beaver is entirely herbivorous and feeds on 

 the bark of many trees. It is especially fond of the bark 

 and twigs of the yellow birch, quaking aspen, poplar 

 and willow. Selecting trees of these species which grow 

 close to the water, the beaver gnaws around the trunk
