Double-crested cormorants
are usually found in flocks, and are one of only two species that prefer fresh
water. In the mid-twentieth century, populations were seriously reduced due to
DDT use, but have begun to bounce back.
Cormorants feed principally
on slow moving or schooling species of fish. Their increase in population has
made them a major predator in the northern areas causing a reduction of young
fish in the smaller lakes.
Can be found on rock
islands and gather in colonies. It is common to see them with their wings
spread out to let the sun dry their un-oiled wings
