Double-crested Cormorants live year-round along the Pacific Coast of North America from Northwestern Mexico all the way up to the Aleutian Islands of Alaska. They also live year-round in parts of Florida. This species winters in in the Southeastern United States and Northeastern Mexico. In spring, they move into the Northern United States and Southern Canada where they can be seen migrating in large flocks.

Diet and Foraging Habits

Double-crested Cormorants primarily eat fish which they catch by hunting them underwater. They will also eat other aquatic creature such as crustaceans and amphibians.

Where to Find This Bird

Double-crested Cormorants can be found in a variety of places with all of them usually being near bodies of water. Look for this species in trees lining lakes and ponds as well as in marshes. Often times, Double-crested Cormorants will congregate in large groups on islands or other places with adequate perches as they dry their wings and survey for prey.

Summary

Cormorants are unique, lanky birds that are a common sight near the water. Knowing the habits, range, and key identification features of each of these species can be incredibly useful in knowing what to look for in the field.

Brandt’s Cormorant

Brandt’s Cormorant
Identification

Adult Brandt’s Cormorants are a shiny black color with pinkish gray behind the gular. Their most notable feature is the bright blue gular pouch and blue eye that sets this species apart from other cormorant species. They also have “whiskers” on the face behind the gular as well.

Immature birds are brown with a lighter colored chin and look much drabber overall.

Range

Brandt’s Cormorants live along the Pacific Coast of the continental United States year round from Washington all the way to Mexico. During the winter they can be found more north and more south than other times of the year expanding into the shores of Alaska and Mexico.

Diet and Foraging Habits

Brandt’s Cormorants feed by diving into the water and catching fish. They are sight feeders and are adept at swimming both at the surface and deep in the water. Brandt’s Cormorants are known to eat an extremely wide variety of fish species and will forage in large groups of fish eating predators including other Brandt’s Cormorants, gulls, terns, and even sea lions.

Where to Find This Bird

Brandt’s Cormorants are almost exclusive to coastlines of the Pacific Ocean. They can be seen in large colonies and are even found on Cliffside’s high up above the water.

Identification

Neotropic Cormorants are small members of the cormorant family. Adult birds are a shiny black color with white feathers on their head, back, and wings. They have a white triangle on the base of the bill known as a gular. Neotropic Cormorants have yellowish orange on the base of the bill and a turquoise-colored eye. Juveniles are lighter in color overall, sporting brown coloration instead of black.

Range

Neotropic Cormorants live year-round in South America, Central America, much of Mexico, and the Gulf Coast of the United States. While much of the population is not migratory, some birds move north in spring and have a habit of turning up north of their normal range.

Diet and Foraging Habits

Neotropic Cormorants eat mostly fish, but will also consume insects, crustaceans, and amphibians. These birds are sight feeders and search for prey underwater where their streamlined bodies make them adept swimmers.

Where to Find This Bird

Neotropic Cormorants live in a wide variety of places including inland lakes, saltmarshes, and along ocean coastlines. They can often be seen perched in branches and other structures near water keeping watch for food.

Neotropic Cormorant vs. Double-crested Cormorant

Every spring, large flocks of dark-colored, long-necked birds make their way across North America: Double crested Cormorants. Due to their distinctive shape, these birds are easy to identify in the marshes and lakes that they inhabit. However, there is another cormorant species that occasionally makes its way north from central and south America that looks incredibly similar to its double-crested relative: The Neotropic Cormorant.

In most places in the United states, with the exception of some southern states, the Neotropic Cormorant is extremely uncommon. For that reason, it pays to know what to look for in order to find a rare species or simply to differentiate them from Double-crested Cormorants in states where the two species regularly overlap.

Size

The first thing to look at is the size and shape. Neotropic Cormorants are shorter and sleeker than Double-crested Cormorants with an average 61cm height, and a wingspan of 102 cm compared to the 70 to 90 cm height and 114 to 123 cm wingspan of the Double-crested Cormorant. In addition to the basic size difference, the Neotropic Cormorant’s tail will appear longer (compared to its body) than the Double-crested Cormorant’s tail. These characteristics are most noticeable in flight when directly compared to the other cormorant species but can also be seen when the birds are perched.

Size Comparison

Lore Color

Size can be difficult to determine without a direct comparison to other nearby birds. Fortunately, there are some other field marks that can be used to distinguish these two species. First, note the lores (just above the bill, going from the eye to the bill) on the Double-crested Cormorant. Both juveniles and adults display yellow to orange colored lores. In Neotropic Cormorant, the lores are significantly darker. When comparing these two next to each other, there is actually a significant difference.

Double-crested Cormorant
Note the bright orange lore, 90 degree angle of the gular, and the  lack of white around the gular on this Double-crested Cormorant

Gular

Another important area to note on these birds is the gular (which is essentially the upper throat). Both species have orange or yellowish gulars, but the shape is different depending on  the species. If you look carefully, you can see that the Neotropic Cormorant has a gular that angles toward the bill in an acute angle. The gular on the Double-crested Cormorant angles far less, and in many instances makes a 90 degree angle.

Another field mark birders regularly use to distinguish these species is the white triangular marking that lines the gular on the Neotropic cormorant. It’s very obvious in adults but less visible in juveniles.

Neotropic Cormorant
Note the dark lore, acute angle of the gular, and white triangle around the gular on this Neotropic Cormorant

Review

It can be really difficult to make a positive ID based on just one characteristic between these two species. For that reason, it’s best to look at all the field markings. As a whole, an adult Neotropic Cormorant will have a smaller, sleeker stature, a longer tail, dark lores, a gular that acutely angles in toward the bill, and a white triangular marking around the gular. An adult Double-crested Cormorant will be larger and blockier, have a shorter, stubbier tale, brightly colored lores, a gular that is less angled near the mouth, and no white triangle mark around the gular.

A Double-crested Cormorant can be identified by regarding these characteristics:

Larger size
Bulkier Appearance
Brightly colored lores
More obtuse angle where the gular meets the throat
Lack of white around the gular

A Neotropic Cormorant can be identified by the characteristics below

Smaller size
Sleeker appearance
Dark lores
Acute angle where the gular meets the throat
White triangle marking around the gular in adults

With these traits in mind, it becomes much easier to differentiate between these two species. We hope you found this post helpful. Be sure to like and subscribe for more ID tips, and leave a comment below if there are any specific species you would like to see an ID tips about.
