Birds form part of vertebrates in the animal kingdom and have numerous species already discovered and there are probably way more that are still not in our knowledge. They play a vital role in the ecosystem’s food chain and food web and help to keep everything balanced in mother nature’s great backyard.
But in the grand scheme of things… Are birds consumers, producers, or decomposers?
A majority of bird species in existence today are mostly consumers. They cannot produce their own food using the sun. Some birds are scavengers and are good at ‘cleaning up’ but they cannot be considered decomposers either as they do not break things down at a molecular level.
Another intriguing thing is that birds can further be classified as either primary, secondary, or tertiary consumers depending on what (or who) they usually eat to survive.
How true is all this? Well, there is only one way to find out…

Birds As Consumers
1. Is A Bird A Primary Consumer?
That depends on which bird you are talking about here…
The thing is, birds too have a wide range of diets that their different species follow to get and sustain their energy requirements. They also have all the different kinds of consumers under their ranks and this helps form part of the greater, complex food web.
All in all, a major factor that helps us when trying to determine whether a bird is a primary, secondary, or tertiary consumer is its size.
Most of the time, the bigger the bird is, the greater the chances of it being a secondary consumer. On the other end, the smaller a bird is, then the bigger the chance that it’s a primary consumer.
Primary consumers’ main diet majorly consists:
- Some types of grass
That said, small bird types such as sparrows, cardinals, and larks are better classified as primary consumers. This is because their main diet involves feeding on seeds alone.
Other examples of birds that are primary consumers include:
Except for hummingbirds from the list above, the rest of the birds have short and hard beaks that are pointed in most cases. This evolutionary adaptation allows them to pick seeds and grains with amazing precision.
To add to that…
Parrots, toucans, and parakeets are born with exceptionally strong and curved beaks that allow them to break nuts and climb trees with ease.
The hummingbird, on the other hand, has a long, slender beak. The beak is an adaptation that allows them to reach the deeper parts of a flower so that they can suck nectar.
2. Is A Bird A Secondary Consumer?
There are a lot of birds that are categorized as secondary consumers in the present food chain and most of them are either carnivores or omnivores.
To clarify how this works…
Carnivorous birds are those that cannot directly feed on producers such as plants due to the nature of their digestive systems. And because of this, they mainly depend on meat from primary consumers to get their fill of energy.
Their prey is small animals most of the time and they could range from rodents, fish, worms, insects, snakes, and even other birds…!
Also, because of their unique diet, their bodies are almost always large and are well-adapted to hunting and devouring their prey.
For example, a majority of carnivorous birds have sharp claws (e.g., the talons of an eagle) that help them catch and place a firm grip on their prey. You will also notice that they have sharp, hooked beaks that allow them to rip and tear through flesh easily when they are feeding.
Some of the most commonly known carnivorous birds include:
On the other hand, we have omnivorous birds that are also classified as secondary consumers.
These types of birds usually rely on both plants and animals to sustain their energy requirements in the food chain. They will freely eat seeds, fruits, and nectar at one moment and then switch their palate to insects, worms, and fish spontaneously!
Which birds do you think form part of the omnivorous class?
A few great examples include:
- Ruby-throated hummingbirds
3. Is A Bird A Tertiary Consumer?
Tertiary consumers, as you know, are animals that feed on secondary consumers in a food chain. They are also popularly known as apex predators in other terms.
Now, tertiary consumers rarely have predators preying on them since they sit at the top of the chain. However, they still turn into a food source for scavengers when they die.
Some good examples of tertiary consumer birds include:
- Secretary birds
And as much as they eat probably anything that’s below them, they depend on the survival of both primary and secondary for their kind to exist.
Are Birds Producers?
Birds are not classified as producers in the trophic sense. This is because they depend on other organisms for food and energy.
Producers are organisms that can make food on their own and utilize it to sustain their lives. They mostly do this through the help of the sun and other natural resources.
A dominant example of these is the plants. They use photosynthesis to manufacture food in their leaves and other parts that will later sustain their general growth.
But, for birds to survive, they need to feed on the seeds, fruits, and leaves made by these plants.
Are Birds Decomposers?
Birds are not decomposers, but there are a few that can be labeled as scavengers. Scavenger birds normally feed off carrion and the remains of other dead animals.
A good example of scavenging birds includes the vulture and the crow.
Decomposers are microorganisms that break down the bodies of dead animals or plants in the ecosystem. Many organisms that fall under this group in the food chain are mainly bacteria and fungus.
They break down all dead organic matter on the earth at the molecular level – releasing essential nutrients and minerals back into the soil. These minerals and nutrients are then used up by producers (plants) to make their own food.
The plants are then eaten by primary consumers, which are eaten by secondary consumers, then tertiary, scavengers… and the cycle continues.
Frequently Asked Questions
Is a bird a consumer or predator?
A bird can be either a primary, secondary, or tertiary consumer depending on where they sit on the food chain.
Primary consumer birds like hummingbirds will only eat from plants to attain their energy requirements. Others like hawks, seagulls, and even penguins strongly rely on feeding off primary consumers to survive.
At the top of the chain are predatory birds like eagles which can devour virtually almost anything that’s below them in the food chain. These include fish, other birds, rodents, and small mammals.
Are birds carnivores?
Several birds can be openly classified as carnivores.
These include birds such as hawks, eagles, vultures, and falcons. Their bodies have adapted to eating only flesh from either primary or secondary consumers for their survival.
And as such, you will find that they have evolved physical features like sharp claws, great vision, and hooked teeth to help them in their trade.
What is a consumer animal?
A consumer animal is that which depends on eating either producers or other smaller consumers to sustain their lives.
There are 3 types of consumers in the ecosystem namely the primary, secondary, and tertiary consumers. Primary consumers feed directly on producers while secondary consumers feed on the primary consumers to survive. Great examples of primary and secondary consumers are hummingbirds and raptors respectively.
At the top are tertiary consumers which can feed on both the primary and secondary consumers. A good example is an eagle, owls, and petrels.
