Beavers (Castor canadensis) are the engineers of
the Elkhorn Creek Valley. Their dams hold back water that keeps the
soil moist, and allows many varieties of plants to grow. Silted in
beaver ponds eventually become meadows that eventually support tree
growth. Their backed-up ponds usually make excellent fishing holes
for Brown Trout.
||The Mountain Bluebird (Sialia currucoides) is very common along
roadways through meadows. Numerous boxes have been erected to
support these cavity nesters. Arriving as early as late February
or early March, Mountain Bluebirds sometimes produce as many as three
families a season.
|The Yellow-bellied Sapsucker (Sphyrapicus varius) leaves lines
of small holes in the trunks of Aspen trees in its search for
insects. The sap leaking form the holes catches insects that make
a tasty meal.
