REINDEER
 
Rengifer tarandus
 





DISTRIBUTION AND HABITAT
The Reindeer is a widespread and numerous species in Eurasia, North America, the arctic islands of Scandinavia, Finland, the western region of Russia and in West Siberia.
 
DESCRIPTION
Females weigh vary in the range of 79 and 116 kg, and the males (“bulls”) are tipically larger,  weigh between 92 and 210 kg. Both sexes grow antlers.  The knees of many species of reindeer are adapted to produce a clicking sound as they walk, helping the herd to stay together in their nocturnal migrations.


 
REPRODUCTION
Mating occurs from late September to early November. A male will stop eating during this time and lose much of its body reserves. Calves may be born the following May or June.



DIET

They eat lichens, especially reindeer moss, leaves of willows and birches, as well as sedges and grasses.
 


SOCIAL BEHAVIOR
During the migration herds will group together up to 100,000 animals.
 


LONGEVITY
Reindeers can live up to 12-15 years.
