Interesting facts

It's a quirk of language.
  
In English many animal groups are named based on some virtue or vice or other idea associated with the animal.  
1)Lions were traditionally seen as regal and elevated so their group is called a pride.  
2)Owls are associated with wisdom so a group of owls is called a parliament. 
3) Monkeys form troops, many animal groups are called herds, birds that don't have a specific name for their groupings form flocks,   
3)The proper name for a group of crows is "murder".
