All birds stand out in one way or another. More often than not, their beaks manage to catch our attention.
You don’t have to an ornithologist or a bird-watcher to appreciate these beautiful creatures.
You may have noticed that different birds have different beaks. This is because they live in different regions and habitats.
They also have varied dietary needs, which is why birds that follow a similar diet tend to share a characteristic beak.
Beaks are essential to all birds and are telling of the kind of food they eat, their behavior, and their ability to adapt.
What Is a Beak?
Biology defines a beak as a kind of mouth where the jaw is encased in keratin, and contains no teeth.
Keratin is a kind of protein that is also found in human nails, hair, and skin.
Beaks bear a strong association with birds, but other animals such as turtles and squids also have them.
Types of Beaks of Birds
If you are under the assumption that different beaks serve different functions, you wouldn’t be wrong.
Before we learn about the kinds of beaks there are, we need to understand that beaks can be divided into two broad categories: generalist and specialist.
Birds with generalist beaks employ a variety of techniques to gather food. Their beaks are suited to eat different kinds of food.
Their beaks do not have a particular shape. They are not very long, nor are they too short, and they don’t have a special tip serving a special function.
These birds are also more resilient, seeing as they are able to eat anything. They adapt very well to the environment they’re in and make do with whatever food they can find.
Here are some examples of birds that have generalist beaks:
- House sparrow
- Common grackle
- American robin
- American crow
- Northern mockingbird
Specialist beaks, on the other hand, allow birds to perform a specific function.
This function might not just be limited to eating, and can also pertain to building nests and procreating.
Birds with specialist beaks have a very limited diet. Decades of evolution have granted them the beak and skills they need to catch prey.
As you might have guessed, birds with specialist beaks can be categorized according to what they eat.
Let’s now discuss the different birds and beaks within this category.
These are birds that feed on vertebrates. All birds of prey come under this category.
Their beaks are strong with a pronounced hook, and are fixed to the skull. When closed, the upper part of the beak covers the lower part.
The beaks are designed so that they are instrumental in ripping apart flesh. Falcons, vultures, and eagles all use their beaks in the same way.
These birds love fruit and also eat seeds. Their special beaks help them puncture fruit, open it, and access the pulp and/or seeds inside.
Frugivorous birds have curved beaks that are somewhat short. Their beaks feature a special tip that helps them extract the edible portion found in seeds.
As for the lower part of their beaks, it is sharp and flat. This is perfect for when they come across fruits that are harder and tougher.
Interestingly, out of all the birds, frugivorous birds are the only ones to be able to move the upper part of their beaks without using the lower part. This means they can use more pressure to split seeds or fruit.
Birds in this category include c, parrots, macaws, and cockatoos.
As you can probably guess, these birds feed on insects.
If a bird is hunting while flying, its beak is open to trap prey. Such birds have beaks that are flat, wide, and short.
This allows them a greater surface area to catch insects. Swallows, nighthawks, and swifts come under this category.
Insectivorous birds that prefer to hunt crawling insects and bugs on the ground have straight, short, thin beaks that are almost like tweezers.
They are able to pick out insects that are small and move quickly. Hoopoes, American robins, and woodpeckers come under this category.
Beaks for Drilling
Speaking of woodpeckers, their beaks are built to endure repetitive hammering.
If you’ve often wondered why woodpeckers don’t get headaches, it’s because their skulls are such that they protect the brain.
All that boring and drilling does not cause any concussions whatsoever.
The diet of granivorous birds consists of seeds.
Their beaks are interesting in that they have a conical form, and are short. This helps them break apart seeds no matter how tough or hard they are.
These birds dive into bodies of water to catch fish. Their beaks feature a curved tip, and are quite strong and large.
They are also lined with serrations, which helps keep their prey in their mouth.
Albatrosses and seagulls are both piscivorous birds.
Storks and spoonbills are examples of this kind of bird. Waterfowl generally have longer beaks with no particular shape.
Called spatulate beaks, they help wading birds pull out prey such as small animals and mollusks from marshes and ponds, while making sure the bird does not have to dive in.
Birds such as hummingbirds belong to this category. They feed on the nectar of flowers. Their long, thin beaks make for easy insertion.
Not all nectarivorous birds feed on the same flowers. Owing to this, their beaks have different shapes.
Talking about hummingbirds, for instance, some species feed on flowers that cannot be accessed by other fauna.
Other examples of nectarivorous birds include the buff-tailed coronet and red-throated sunbird.
Filter Feeding Birds
Known by their flat and wide beaks, these birds are adept at gathering food from riverbeds and ponds.
Flamingos, ducks, and swans are all great examples of filter-feeding birds.
They have nifty beaks in that they are designed to filter out water and hence separate the organisms that these birds ultimately eat.
Aside from the beaks discussed above, there are some that transcend these categories.
There are more than a few birds that have unique beaks made for ultra-specific functions.
New Zealand Plover
Did you know this is the only bird with the ability to shift its beak to either side?
It does so in order to catch flies.
This bird’s beak curves in an upward direction.
This allows it to trap prey that is small in size.
This fascinating bird is the only one with a beak where the lower part is actually longer than the upper part.
Given this design, black skimmers can catch fish while immersing their beak in water. Doing so helps them effectively fish out prey.
Curlews are an interesting sight. Their beaks are longer than their bodies!
You might think toucans’ beaks are just beautiful to look at, but you couldn’t be more wrong. Toucans have multifunctional beaks.
They use them to gather fruit and peel off its skin, no matter how thick.
They also use their beaks to intimidate predators, defend their territory, and attract partners for mating.
What’s truly amazing, however, is that their beaks play an integral role in controlling their body temperature.

Miscellaneous Fun Facts About Beaks
Haven’t had enough of beaks just yet?
Here are some more fun facts!
Beaks and Bills: What’s the Difference?
Both these terms are correct when referring to birds’ mouths.
That said, however, most people tend to use the word beak to describe sharper beaks that are more needle-like in appearance.
The word bill is reserved for beaks that are flat, soft, and somewhat rounded.
Do Beaks Function As a Nose?
There are numerous species of birds with nostrils on the beak.
In this case, because beaks are used for both eating and smelling, the term nose would be limiting and incorrect.
Do Other Animals Have Beaks?
Yes! Even though birds seem to enjoy an exclusive relationship with beaks, there are other animals that also have them.
They might look different from birds’ beaks, but turtles, platypus, octopi, and even proboscis insects have beaks.
