Canada geese migrate through Illinois every spring and fall. In the southern swamp there is plenty of food.
The river otter has a streamlined body and webbed feet, it is an excellent swimmer, and is well adapted for life in the water. It is in the weasel family. River otters feed on fish, muskrats, birds, turtles, frogs, freshwater mussels, and aquatic insects. They give birth to as many as six young in February or March.
The river otter once lived throughout Illinois, but fur trapping and habitat loss almost eliminated it by the mid 1800s. Otters have been reintroduced to Illinois and are increasing in numbers.
