Do Geese Eat Algae? (What you Need To Know)

Geese will generally eat whatever they can find in the pond and swamps they live in. So, they will certainly eat algae that are floating on the surface.

However, it’s important for their health not to eat too much of it, this is because yes, they have decent nutritional values but, they enhance their health issues by worsening their digestion system.

Where Can Geese Find Algae?

Geese can find algae in several different places. One of the most common areas is a lake or pond. Geese love to hang out around these bodies of water especially in the summer months, and they are often found swimming around in them. This provides them with a great opportunity to pick up algae since it grows in abundance on the surface of the water, making it easy for them to access and eat.

Some types of algae grow very close to land, which allows geese to go out just feet from their pond and eat some while they are defecating. They also flock out onto grassy areas where there is plenty of grassy tall plants that have growing algae on their roots at times.

However, even though a goose usually has access to an easy food supply such as an algae patch growing out of water or on land near water, not all types have a high protein content so they prefer other types once they have had enough of this type. Birds are also known to eat other things such as rodents, frogs and insects as well, which can also provide them with some nutrients that help give them energy. Algae is not typically the only thing they eat but it will provide some extra nutrition that gives them strength and sustains them when there isn’t much else available nearby that is suitable for their tastes.

Are Algae Safe For Geese?

In some cases, algae is not safe for geese, especially if it has turned a different color than the typical greenish tint that it usually has. For example, if there is too much bacteria in the algae then it may not be safe to eat because of the potential for sickness and even death. However, this is not always true since there are some types of algae that are able to withstand more bacteria than others and can be beneficial to eat as well as safer since they will have a better nutritional value.

The only way to know if you have an algae patch brimming with nutrients or if you need to keep your distance from it is by first knowing the harmful things that can be in an area of water or land where there might be an overabundance of algae. It is important for you to learn about these dangers beforehand so that you can determine whether or not this food source is suitable for your geese.

Besides being able to tell if the algae has been contaminated by bacteria, you can also tell by the texture and coloring of the algae itself. If it looks slimy and white in color, you should never feed this to your geese. Instead, opt for green, brown or red algae.

When preventing your geese from consuming contaminated algae, there are some things that you can do in order to keep down the possibility of sickness or death. First and foremost, keep their water clean at all times. This way, your geese will have a fresh water source available whenever they need it.

What Do Geese Eat In A Pond?

There are three more things that your geese can eat in a pond, as well as some additional things that are less desirable.

Herbs and Veggies For Geese: Certain foods actually make great additions to the pond ecosystem. One of the best for your geese is what’s known as pondweeds. These plants can grow in any type of water environment, including ponds, ponds with fish and even fresh or salt water marshes. When they first start growing in a pond, they’ll be green and soft. Over time though, they will become thick and covered with orange or red blooms.

The best part about these plants is that they’re so incredibly nutritious because of all the tiny seeds that have been stored on its surface over time. The seeds themselves are packed with a high concentration of protein, calcium, vitamins and other nutrients that make them a useful addition to what your geese will eat for food in a pond

Are Geese God For My Pond?

Having a flock of geese around is great for your pond in a lot of ways, whether you have an ornamental duck pond or a fishing pond. Not only do they help to keep it clean, but they also fertilize the water with their droppings (a.k.a., goose poop). In other words, they make your fish happy!

However…there are also some problems that may come up as well; most goslings when left unsupervised can end up ruining the ecosystem in your pond.

So it’s important to keep an eye on them and prevent them from doing too much damage.

The following is a quick overview of some of the pros and cons associated with having geese in a body of water:


• They eat up algae, keeping the water clean for fish and other animals.

• They also help to fertilize the water for plants or vegetation that grow in the pond bottom or along the shoreline, adding oxygen to the water (especially important if you have fish).

• Goslings can become pets or cheap lawn mowers if you don’t mind their noise.


• Geese are big birds with large appetites so they tend to make quite a mess when they’re eating! Their food plus their waste can end up polluting your pond in several ways, including causing algae blooms and excessive growth of weeds and aquatic plants. This usually happens when there is not much plant life around that is being eaten by herbivores (i.e., fish). Also, if left unsupervised, they may even start digging at the bottom of your pond creating mud pits all over it!

• The geese themselves can be territorial (especially during mating season) so if you don’t want any trouble, it’s best to keep only two pairs per acre of land – more than this will just cause trouble in dividing their territories.
