Do Ducks Eat Frogs? Yes, They Get Protein From Amphibians!

Ducks do eat frogs! Whether it’s frogs or tadpoles, ducks, especially the North American Mallards, hunt them with expertise. They attack frogs for having nutrients like protein, and they even balance the ponds or wetlands environment by consuming some of them.
It’s crystal clear that ecology has an interrelation between ducks and aquatic creatures like frogs. To find out how, please go a little further! You may also get some other necessary facts based on ducks eating frogs.

5 Reasons Why Ducks Eat Frogs

As birds of prey and omnivore birds, ducks will surely attack frogs. Particularly, we found some reasons behind ducks’ wildness on frogs.
- Due to ducks’ omnivore and opportunist activities, they hunt frogs and their babies, which we call tadpoles or toads.
- If the food supplies are not fulfilling for ducks, they eat frogs.
- Frogs have high protein, so ducks may consume them for the development of overall health.
- As expert natural foragers, ducks may forage, swim, or dive into the pond to look for frogs as their food source.
- Ducks are fast swallowers, so when confronting frogs, they will eat them. The video we’re sharing will clear the fact!

4 Popular Ducks Species That are Mostly Shown Eating Frogs
Almost all the ducks have wild nature, but some of them have excessive. And my intention is to introduce the most common duck species that eat frogs. Have a look at this!
1. American Mallard

Yes, mallards are wild ducks, so definitely they’ll prey on frogs. If you see what ducks eat in the wild, you may get a more clear view of ducks’ nature. They’re especially notable ducks as a frog hunter. Such waterfowls primarily forage on water surfaces such as wetlands, ponds, and lakes.
You may know during the nesting season, male and female mallards look for high proteins. So, they’ll eat frogs, toads, or tadpoles from the ponds or lakes. One more thing is mallards have a large appetite, and they’re exceptionally aggressive for food sources.
2. Carolina (Wood Ducks)
Yes, wood ducks usually hunt frogs. They’re considered cavity-nesting waterfowl found in wetlands or forested locations. Similar to other North American duck species, the wood duck is a predator of frogs.
3. Indian Runner
Indeed, Yes, Indian Runner, as a domestic duck, will kill frogs. Due to their foraging behavior, ducks will eat any small creature they find.
In general, runner ducks are kept to maintain agricultural and pest control tasks. But they can contribute to the pond’s environment as well. What you’ll have to do is let the duck spend some time on the pond.

4. Dark-Plumaged Muscovy
Indeed, muscovy ducks are no exception as frog eaters. Such fowls are considered domesticated Central And South American Ducks with omnivore nature. So, they’ll look for any food source, like insects, small fishes, and frogs as well.

What About Big Semi-Aquatic Frogs: Can Ducks Eat Bullfrogs?
Yes, ducks will attack such American bullfrogs as well. But the thing is, keep the baby duck away from them. Because the story may change, and you’ll discover bullfrogs are hungry for ducklings or even cats! How Brutal!
It is weird but true that such large amphibians can attack small creatures and even swallow them entirely. So, if it’s an adult fowl in the pond, bullfrogs are in trouble!
Baby Duck Near The Wetland: Can Ducklings Eat Frogs?
No, according to me, small ducklings shouldn’t try to eat frogs. They have sensitive small beaks, so if they attack frogs, they’ll surely encounter trouble while consuming.
But when it’s about tiny insects, crustaceans, or tadpoles, they’ll eat it comfortably. They won’t even avoid frogs as a polite baby duck. They’ll try to eat them too because of their nature!
So, if it’s your backyard duck, don’t let them go to hunt around water bodies until they become an adult. And if they confront the bullfrogs, be ready to see the reverse.
Do Ducks Eat Frogspawn?
No, usually, ducks avoid eating frogspawn, but they eat it when they miss catching frogs or tadpoles. Frogspawn is basically a gelatinous egg mass that is jelly-like things, which is not a necessary part of ducks’ diet.
What Are The Deep Relationship Between Ducks And Frogs?
Ducks and frogs usually coexist in the exact locations with similar ecosystems. Frogs are clearing insects, and ducks are doing the same job by eating frogs, so ecological interaction is there, and it’ll be clearer if you read the facts we are including.
Relationship | Description |
---|---|
Ducks as predator | Frogs are ducks’ protein source during nesting time. |
Ducks and frogs as competitors | In the same wetlands, ponds, or lakes, ducks and frogs compete for food sources. |
Monitors ecosystem | The amount of ducks and frogs in the wetland ensures the condition of the ecosystem. Whether ducks eat frogs or frogs eat insects ultimately keeps the ecosystem in control. |
Mutualism between ducks and frogs | Ducks assist frogs by stirring up the residues and letting them access food easily. |
Transmit Diseases | Ducks may transmit ranavirus to frogs or maybe the poisonous frogs make the duck sick. |
4 Advantages of Ducks Consume Frogs

Now you know ducks get frogs as their food source. But how do frogs or other stages of frogs contribute to the duck’s health and environment? We found some notable things for you!
1. Frogs As a Food Source
Ducks consume frogs and other small creatures when looking for food sources. Where frogs have high protein and other nutrients to offer.
2. Control Pest
In nature or the agricultural field, frogs benefit ducks by consuming pests.
3. Health Benefits
Ducks love to get frogs as their food. If you consider health benefits, you’ll find:
- Frog contains fat, an advantage that keeps the duck’s body warm during winter.
- For having iron in frogs, blood regulates ideally and helps prevent anemia in ducks.
- And we already said protein is there to help the waterfowl for breeding.
4. Well-Balanced Environment
The high population of ducks may cause a rise in nutrient levels, resulting in eutrophication and algae blooms. Ducks, as predators, contribute to the wetland or aquatic ecosystem by consuming frogs. It helps other species in water.
3 Potential Risks When Ducks Eat Frogs
Some possible issues may be encountered along with environmental and health benefits for ducks. Therefore, keep some things in mind!
1. Frogs Toxicity
You may not know about the batrachotoxin in frogs like poison dart frogs. If duck predator hunts them, the toxin attacks the nervous system and cause difficulties for your domesticated ducks. Even wild ones should not eat frogs. The problems might be as follows:
- Muscle contractions
- Salivation
- Convulsions
- Death.
2. Transmit Disease
Some frog species carry parasites that transmit to ducks while they consume. For example, frogs may contain Salmonella bacteria, which is hazardous for ducks. So, it’s a matter of concern when ducks swallow frogs or bufo.
3. Frogs’ Poisonous Fluid Is Risky
Frogs like bullfrogs are pretty dangerous. Also, some species get frightened, or they secrete a poisonous fluid for defense. If they use it, ducks become in danger!
FAQs
We added a Q&A section with some common questions that users may ask. We hope it brings some facts that may come to your mind!
Q. Will Ducks Eat Frogs And Toads Too?
Yes, ducks are opportunist eaters, so not only frogs but ducks also eat tadpoles and toads.
Q. What Duck Species Don’t Eat Frog?
Duck’s dietary preferences may vary, but almost all the species eat frogs. But ducks who love to remain herbivorous or are vegetarian possibly won’t eat frogs.
Q. Can Ducks Eat Large Frogs?
Yes, ducks will attack giant frogs, but usually, they target small creatures.
Wrapping Up
In short, ducks will have no problems consuming frogs in general. Particularly, the Mallard, wood, runner, or even muscovy ducks have the habit of hunting small creatures like frogs. But take the ducks away from bullfrogs!
Other than that, it’s crystal-cleared that ducks contribute to the wetland’s ecological system by eating the amphibians. But here is a slight concern about the toxicity in frogs. Who cares! Even if you stop, they won’t cooperate; rather, swallow frogs as fast as they can!
