Birds Similar To Cormorants – 5 Birds That Look Like Cormorants

In the vast world of aquatic avians, cormorants stand out with their distinctive silhouettes and impressive diving abilities. But they’re not alone in their prowess. Several other bird families have evolved similar traits, creating a group of birds similar to cormorants that can leave even experienced birdwatchers scratching their heads. This fascinating phenomenon of convergent evolution has resulted in a variety of species that, at first glance, might be mistaken for cormorants. Let’s plunge into the world of these aquatic look-alikes and uncover the subtle differences that set them apart from their cormorant cousins.

Understanding Cormorants: The Benchmark for Comparison

Before we dive into the world of birds similar to cormorants, it’s essential to understand what makes cormorants unique. Cormorants are large, fish-eating birds known for their:

• Dark, often iridescent plumage
• Long necks and hooked bills
• Webbed feet for efficient swimming
• Ability to dive deep and swim underwater for extended periods

These characteristics have evolved to make cormorants excellent fishers, perfectly adapted to their aquatic lifestyle. We’ll see how nature has crafted other species with comparable features, resulting in birds that bear a striking resemblance to cormorants despite being from different families.

The Magnificent Five: Cormorant Cousins and Copycats

1. Anhinga: The Snake Bird

Among the birds similar to cormorants, the Anhinga, also known as the snakebird or darter, is perhaps the closest look-alike. These fascinating birds belong to the family Anhingidae and are often found in the same habitats as cormorants.

Key features of the Anhinga that make it one of the birds similar to cormorants:

• Long, snake-like necks that seem to disappear underwater
• Sharply pointed bills to impale fish
• Dark plumage that can appear similar to cormorants when wet

Unlike cormorants, Anhingas have a unique way of drying their wings. They’ll often be seen perched with wings spread wide, creating an unmistakable silhouette against the sky. This behavior is due to their lack of oils in their feathers, which allows them to swim lower in the water but requires them to dry off more frequently.

“The Anhinga moves through the water like a living spear, silent and deadly.” – John James Audubon

Interesting fact: Anhingas can regulate their buoyancy by adjusting the amount of air in their respiratory system, allowing them to sink or float as needed. This adaptation is shared by other birds similar to cormorants, showcasing how different species have evolved similar traits to thrive in aquatic environments.

2. Booby Birds: Divers with a Difference

Boobies, despite their comical name, are impressive large fish-eating birds that share many characteristics with cormorants. They’re part of the Sulidae family, which includes gannets, and are another excellent example of birds similar to cormorants.

Notable booby species:

1. Blue-footed Booby
2. Red-footed Booby
3. Masked Booby

While boobies share the cormorant’s love for fish and are often considered birds similar to cormorants, they have some distinct differences:

Feature	Boobies	Cormorants
Feet	Brightly colored	Usually black
Bill	Conical, serrated edges	Hooked at tip
Diving style	Plunge from heights	Surface dive
Wing shape	Longer, more pointed	Shorter, rounded

Boobies are known for their spectacular plunge-diving, dropping from heights of up to 100 feet to catch fish. Their adaptations for this hunting style include:

• Air sacs under the skin to cushion the impact
• Nostrils that close underwater
• Eyes positioned to provide binocular vision when diving

These adaptations showcase how birds similar to cormorants have evolved unique features to exploit similar food sources in different ways.

3. Grebes: The Freshwater Phantom

Grebes are another group of birds that might be mistaken for cormorants, especially at a distance. These freshwater divers have some fascinating adaptations that set them apart from other birds similar to cormorants.

Grebe characteristics that make them birds similar to cormorants:

• Sleek, streamlined bodies for efficient swimming
• Ability to dive and swim underwater for long periods
• Dark plumage that can appear similar to cormorants in certain light

However, grebes have several unique features that distinguish them from cormorants and other birds similar to cormorants:

• Lobed feet instead of fully webbed feet
• Small heads and thin necks
• Ability to sink slowly into the water, almost like a submarine

Waterproof plumage is crucial for both grebes and cormorants, but grebes take it a step further. They actually eat their own feathers, which line their stomachs and help protect against sharp fish bones! This unique adaptation is not seen in cormorants or other birds similar to cormorants.

Case study: The Western Grebe’s “rushing” display Western Grebes perform an incredible courtship display where they literally run across the water’s surface side by side. This “rushing” can cover distances of up to 20 meters, showcasing the power in their lobed feet. This spectacular behavior sets them apart from cormorants and other birds similar to cormorants, highlighting the diversity within this group of aquatic birds.

4. Loons: The Northern Divers

When considering cormorant vs loon identification, it’s important to note that loons are primarily found in the northern hemisphere and have some distinct features that make them birds similar to cormorants while maintaining their unique identity.

Loon highlights that make them birds similar to cormorants:

• Excellent diving and swimming abilities
• Fish-based diet
• Dark plumage (in breeding season)

However, loons have several characteristics that set them apart from cormorants and other birds similar to cormorants:

• Heavier build than cormorants
• Dagger-like bills perfect for catching fish prey
• Haunting, yodel-like calls that are iconic to northern lakes

Loons are incredibly efficient swimmers, capable of staying underwater for several minutes while pursuing fish. Their legs are set far back on their bodies, making them excellent divers but awkward on land. This extreme adaptation for aquatic life is even more pronounced in loons than in cormorants and other birds similar to cormorants.

Bold fact: A Common Loon can dive to depths of up to 200 feet, showcasing their incredible diving abilities that rival even those of cormorants!

5. Finfoots: The Elusive River Dwellers

Perhaps the least known of our birds similar to cormorants, finfoot species are rare and elusive birds found in tropical water ecosystems. These birds are so rarely seen that they’re often considered a prized sighting for any birdwatcher.

Finfoot features that make them birds similar to cormorants:

• Aquatic lifestyle
• Ability to swim with only their heads above water
• Fish-based diet

However, finfoots have several unique characteristics that distinguish them from cormorants and other birds similar to cormorants:

• Lobed toes (similar to grebes)
• Long tails used as rudders
• Preference for slow-moving rivers and swamps over open water

There are only three species of finfoot in the world, making them a truly unique group among. Their rarity and elusiveness add an element of mystery to these fascinating birds.

Shags vs. Cormorants: Siblings or Distant Cousins?

The term “shag” often causes confusion among birdwatchers exploring birds similar to cormorants. Are shags just another name for cormorants, or are they distinct? This question highlights the complexity within the group.

Truth is, shags and cormorants are closely related, both belonging to the family Phalacrocoracidae. They’re so similar that they’re often considered birds similar to cormorants even though they are, in fact, types of cormorants themselves. The main differences are:

1. Size: Shags tend to be slightly smaller
2. Crest: Many shag species have a distinctive crest on their heads
3. Habitat: Shags are more strictly marine than some cormorant species

It’s worth noting that in some parts of the world, the terms are used interchangeably, adding to the confusion when discussing birds similar to cormorants. This complexity within the cormorant family itself demonstrates how challenging it can be to distinguish between these aquatic birds.

Convergent Evolution: Nature’s Copy-Paste Function

They’re a result of convergent evolution, where unrelated species develop similar traits due to similar environmental pressures. This fascinating process explains why birds from different families can look so alike at first glance, creating the group we refer to as birds similar to cormorants.

Examples of shared adaptations among them :

• Waterproof feathers for efficient swimming
• Long, slim bills for catching fish
• Powerful legs and feet for underwater propulsion
