Cormorant population management on Leech Lake is often cited as a situation where control was necessary to improve the local walleye fishery in Minnesota.

Some walleye stocking was undertaken to address the walleye decline.
How many cormorants are there in Minnesota?
Distribution and abundance appeared similar in both survey periods. The cormorant population in Minnesota experienced a rapid growth phase between 1981 and 1997, with an average growth rate of 4.6 per year. During this time period, cormorants experienced rapid growth across much of the continent as populations recovered from DDT and benefited from legislation and protection. Though complete surveys were not conducted during this period, monitoring in Minnesota estimated 8,000 pairs at 25 sites in 1988, while in 1997, there were an estimated 12,000-14,000 pairs at 66 sites. Data obtained between 2004 and 2010 suggests the rapid growth phase has ended. The state’s population appears to be stable or slightly declining, but counts at some colonies have increased.

In flight, the cormorant can be identified at great distances by its behavior of alternately flapping and gliding while flying in v-shaped flocks. In contrast, ducks and geese have a steady wingbeat.

Often cormorants dry their feathers after swimming by holding their wings out creating a distinctive posture that generates interest and curiosity about this species.

Interesting Facts About The Cormorant
- With such a large variety of species, there are plenty of fun facts to go around about cormorants. Learn more about these birds, or some cool species, below. 1. Feathered and Flightless– For the most part, all species of cormorants are capable of flying through the air, save for one. The flightless cormorant is the largest species of cormorant living today. It is native to the Galapago…
Habitat of The Cormorant
- Cormorants are an aquatic species that is almost always associated with oceans, though they sometimes range into freshwater habitats. Rather than living out over the open sea, most species remain close to the coasts. However, some species are pelagic, which means they live over the open ocean. These birds prefer habitats with rocky cliffs and other suitable nesting habitat, but …
Distribution of The Cormorant
- Different cormorant species range across the globe, save for some Pacific Islands. Any coastal area, and some aquatic areas inland, likely houses a species of cormorant. Different species make their homes in different areas. Some species are more widespread, while others have very small ranges. There are species in North, Central, and South America, as well as Australia, New Zealan…
Diet of The Cormorant
- Generally speaking, cormorants are specialized fish-eaters. With that said, they will feed on other prey when given the opportunity, but fish make up the majority of their diet in most species. Other prey includes eels, snakes, frogs, crabs, shrimp, and more. Species that live in different areas live alongside different prey species, and thus can have drastically different diets from one another.
Cormorant and Human Interaction
- Human interaction varies greatly based upon the region and culture of the area. Surprisingly, some cultures historically used cormorants to capture fish. Though this is not common practice today, the fishermen and birds would work together to catch large fish. This cooperation occurred in Asia, Ancient Egypt, Peru, and India. Unfortunately, many species of cormorants are subject t…

- These birds are frequently sighted swimming along the surface of the water, and diving beneath the surface. While underwater, they will swim along with their webbed feet or wings, and search for prey. Alternately, humans also spot these birds resting on rocks, buoys, and other areas close to the water. While resting, they clean their feathers and stretch their wings out in the sun.
Reproduction of The Cormorant
- Exact reproductive times and strategies vary by species. All species gather in large colonies to lay their eggs and raise their chicks. For our purposes, we will use the great cormorant as an example. This species lays between three and five eggs, usually on a cliff or rocky island. The eggs incubate for approximately one month before they hatch. It takes approximately a month a…
