Beaks and bills are interchangeable terms. Both describe the same mouth part of the birds. However, there is a slight difference in usage of beaks and bills. The difference is in their structure. Beaks are the hard mouth part of birds. Whereas, bills refer to the soft mouth part that is mainly used for feeding purposes. Both beaks and bills are important for the birds. It is helpful for them in performing various daily activities.
In this article I will tell you:
- Difference between bill and beak,
- Structural variation between beak and bill,

Let’s start without wasting time!
Beak vs Bill
The beak and bill are the important body parts of birds that play a significant role in communication, feeding, molting defense etc. These two terms have the same structure, but it varies in usage by the different birds. As a bird owner, here I will tell you the main difference between a beak and a bill.
- Beak refers to the birds of prey that include parrots, eagles and other birds to enable them to hunt and manipulate objects.
- Bill refers to the soft, specialized, broad mouth part that is common in aquatic animals like pelicans, and ducks.
Beak
A beak consists of a pointed, hard structure on the front of the face of the bird. Mostly, it is sharp and curved. It performs multiple purposes that include hunting, cracking seeds, defense, catching prey, preening etc.
Beak’s Characteristics
Some characteristics of the beaks are as follows:
- Hard and Pointed: Beaks are mostly sharp, curved and rigid.
- Curved Tip: Most birds have curved beaks. Mainly eagles and parrots have curved beaks that help them in tearing and gripping food.
- Functional for Feeding and Hunting: Birds having beaks are predators. These birds are parrots, owls, falcons, parrots, eagles etc.
- Beak Usage: Parrots use their beaks to open the hard shells of nuts. Eagles have hooked beaks that help them in holding prey.
Bill
Bill is a soft, more specialized, flexible and broader mouth part of some birds. It is designed to do various activities like catching insects, holding food, filtering water etc. These birds are mostly found in sea waters.
Bill’s Characteristics
Some characteristics of bills are given below:
- Soft and Flattened: Bills have soft, flexible and broader shapes.
- Sensitive to Touch: Bills contain nerves that enable them to feel what is happening in their surroundings.
- Adapted for Specialized Feeding: Birds having bills rely on food items like fish, algae, insects etc for their survival.
- Examples of Bill Usage: Ducks use their bills to swift through mud and water for food. Pelicans have a large soft bill that helps them to scoop fishes from the aquatic source.
Structural Variations Between Beaks and Bills
Beaks and bills of birds are made up of keratin, which is a protein from which human nails are made. Keratin exhibits distinction in the structure of birds’ mouth parts due to which their function also varies. This table shows the difference between beak and bill.
| Feature | Beak | Bill |
| Texture | Hard | Soft |
| Shape | Sharp, curved and pointed | Broad, flexible and flattened |
| Usage | Cracking, hunting, defense, preening, communication etc | Scooping species from water |
| Examples | Owls, hawks, falcon, osprey, parrots etc. | Swans, geese, ducks, pelicans etc |
Functions of Beak
- Hunting and Defense: Hawks have sharp and pointed beaks that help them in killing or holding their prey.
- Manipulating Objects: Birds like parrots use sharp beaks to grip, hold, climb and break hard shells.
- Preening Feathers: Beaks are hard enough to play their role as a tool in helping birds during preening.
- Courtship Displays: Birds use their beaks for interaction in courtship rituals.
Functions of Bill
- Filtering Food: Most aquatic animals have bills that help them filter and catch food from the water.
- Scooping Prey: Pelicans use their hollow and large bills to scoop fish.
- Nesting Material Collection: Swans have soft bills that help them gather nesting material.
- Communication and Display: Bills are more brightly colored as compared to beaks. So, the birds having bills can attract their mates more.
Names of Birds Having Beaks
Names of birds having beaks are mentioned below:
Parrots
Parrots have sharp, pointed, curved and strong beaks that help them in hunting, cracking nuts, preening etc. While climbing, parrots also take help from their beaks.
Hawks and Eagles
Fox and eagles have hooked and pointed beaks that help them in tearing their prey.
Woodpeckers
Woodpeckers have strong and sharp beaks that help them to drill into the bark of trees in search of food inside them.
Names of Birds Heaving Bills
Here, I will tell you the names of birds having bills.
Ducks and Geese
Ducks and geese have broad and soft bills that allow them to carry food from water, mud etc.
Pelicans
It is wrong to say they have the largest beak. They have the largest bill that helps them to hold and carry fish.
Hummingbirds
Hummingbirds have cylindrical-shaped long bills. It helps them to reach the nectar deep in flowers.
Evolutionary Adaptations
Beaks and bills are designed to fulfill the specific needs of the birds, according to their environment. The size, shape, texture and color of the beak and bill is according to the surroundings of the birds.
- Birds in Forests: Birds living in forests have sharp and pointed beaks adapted to drill trees, crack nuts etc.
- Waterfowl: Swans, ducks geese etc have soft bills for catching food from the water.
- Raptors: Owls, hawks, eagles etc have sharp beaks adapted to catch prey.

Frequently Asked Questions – (FAQs)
Why Do Few Birds Need to Have Sharp Beaks As Compared to Having Broad Bills?
Due to evolutionary adaptations, it is important for birds to have sharp beaks as compared to having a soft bills. Their evolutionary adaptation is based on their environmental requirements. Predators require sharp beaks to easily hunt.
Can Any Damage Effects Beak or Bill Growth?
Yes, any damage can affect the growth of the beak and bill in birds. As, they are made up of keratin that helps them in the growth of the mouth part throughout their life. If severe damage occurs, then it will affect the growth and disturb the bird’s ability to eat.
Conclusion
Beaks and bills are interchangeable terms with different textures, functions formation and usage. Beaks are harder, sharper and pointed than bills that are used to scoop and crack food items. Bills are more suitable for drinking water. Understanding the difference between beaks and bills help the owner to know about the behavior and characteristics of the bird.
