How to Protect Corn from Birds (Different Options and Methods)

If you grow corns or you have a corn garden, then the knowledge of how to protect corn from birds can be super handy.

When you grow something, there is always a risk that you will face challenges and difficulties.

One of those challenges will usually come from animals that will eat the corn and cause significant damages to the corn field. 

Why Birds Are Eating My Corn?

Why Birds Are Eating My Corn

Summer is the peak time for sweet corn crop.

Isn’t it nice when you can enjoy tasty corn treats while enjoying the (nice) weather and also the view? Unfortunately, along with the peak season of the sweet corn, it also means peak time for the birds to have a feast on their own.

Everyone hates it when their hard work (putting the corn into a growing plant) is being messed by those pesky flying creatures. 

So, why would bird eat the corn?

Aside from knowing how to protect corn from birds, you should also learn about the nature of the birds.

You have to admit that everyone loves sweet corn, both humans and animals, and the birds are included.

The problem is: Birds would raid the crop, and they will likely outfast you.

Before you can harvest the corn, your garden may already be empty. 

But birds don’t only love those corn crops. They also like eating the corn sprouts or new planted seed, which will create more mess to your garden.

That’s why most corn farmers would protect their corn all through the growing season, to minimize the possibility of damage.

The biggest issues happening to the corn garden may come from blackbirds, crow, and jays, although it’s also possible that other birds may consume the corn. It’s safe to consider that most birds in general would be attracted to the corn. 

The Possible Bird Damage to the Corn

The Possible Bird Damage to the Corn

As it was mentioned before, crows, grackles, and blackbirds love consuming the ears, and it’s not far from the pollination time (early in the period of grain filling).

It seems that these birds develop a certain interest to the developing kernels, which are close to the roasting ear stage or commonly known as the milk stage.

Often times, these birds would come in big flocks. And when it happens, they can cause serious damage to the garden.

People say that these birds may target (and develop a certain preference) over a specific hybrid, but in most cases, these birds may not care at all when they are hungry and they (think that they) don’t have enough food.

Although the damage can be mostly obvious close to the wooded areas and along the edges of the field, it’s possible that the damage extends to the bigger area of the field. 

The reason why these birds focus only to one hybrid isn’t clear up until now, but it’s highly likely connected to the differences in kernel characteristics or kernel maturity.

Different hybrid will have different characteristics, so it’s most likely the reason. Silking date or kernel maturity would be the most important element that determines blackbird’s damage level to the corn garden.

The second important one would be the peak (population) level of rootworm beetles. 

When compared to other veggies, corn fields have the greatest and biggest damage. Not only birds’ feedings are related to the damage, but it’s also the bird droppings.

You see, birds can carry more than 60 diseases and they are transmittable.

When they invade and raid your garden, it’s possible that they may transmit those diseases to the garden.

In the end, the corn’s contamination can affect the farm’s yield and harvest quality quite significantly. 

Before you take the needed measurement, you need to make sure that your garden has been raided, and it has pests’ issues. Check for the symptoms.

The most obvious one is the damaged or missing kernels within the cobs.

Those damaged cobs would turn black or brown when molds start infecting the (damaged) tissue.

And how do you know that it is the bird, not the raccoon, for instance? Well, you can see the shredded leaves on the husk. It shows how the birds work to the kernels to eat them.

It would be too late if the worm is already inside the (protective) husk covering.

So, the way to prevent the worms from entering the husk’s tip is to wrap a rubber band on the ear’s tip.

You can also attach one clothespin to the tip AFTER you see the silk appearing.

If you can block their access from entering the tip, it will significantly reduce the level of damage.

Another alternative is to insert mineral oil to the (dried) corn silks. It will prevent the worms from being able to grip the plants.

Another way is to keep birds at bay. Again, the biggest threat and pest for the corn is birds.

One way on how to protect corn from birds is to use a bird screen or the netting. It is handy to cover the corn beds.

As it was mentioned before, you can your own project to protect the field from the birds’ attack.

Aside from installing automatic stuff or motion-activated fixtures, you can also use exploders to frighten off the birds.

Different Protection Methods and Alternatives

Different Protection Methods and Alternatives

Not many people know this, but there are different methods for addressing different development stages.

Due to these different stages, you need to pay detailed attention to each stage. 

Protect the New Plants

So, if you just start growing the corn, you need to know how to protect the seedlings.

And how to protect corn from birds in this stage? 

  • Make sure that you plant those seedlings deep into the ground. In this way, the birds won’t be able to reach those seedlings or hold on them. After all, birds aren’t raccoons, so they won’t be able to dig those seedlings. Do it one and a half inch (at least) to the soil so birds can get a hold of them. 
  • After you have planted the seedlings, cover them with bird netting. But you need to adjust it as your corn grows. You want to make sure that there isn’t enough room for the birds to get under the net. Be advised, though, that despite the beneficial outcome of the netting, it works super well for smaller corn garden. If you have bigger corn fields, installing the net can be extremely time and energy consuming. 

Here’s the thing you should do when you net the corn field.

Make sure that you measure the area (that you want to cover). Buy the size and proper weight for the netting. Use it to cover the covers.

Feel free to do it within a field level or individually.

You need to remember that netting doesn’t always secure the corn because it doesn’t keep things out.

Even if the birds can’t touch the corn, it doesn’t mean that they can’t damage (or even ruin) it. 

Protect the Grown Plants

One of the most common things about how to protect corn from birds is to perform regular checking.

You want to check whether your corn has produced ears. Cover these ears with the brown paper bags, but make sure that your corn has been pollinated before you cover those ears.

You can see the obvious sign: the corn silk (which is located on each ear’s top area) would turn into light brown. It’s the indication that the corn has been pollinated. It means that you can start covering them. When you combine this with netting, it’s even greater because it adds the extra protection layer. 

Another alternative to protect the crops is to use statues or scarecrows.

If you are going to use the scarecrows, use reflective foil pieces to cover your scarecrows. Choose the ones that can move, especially moving around quite often, so the birds won’t learn that those deterrents are fake.

Don’t underestimate those birds as they are pretty clever.

If they have observed the situation and they see that those scarecrows don’t move at all, they will ignore those scarecrows. 

If you have extra money to spend, consider using motion-activated lights or sprinklers to scare off the pesky birds. You can scare off the birds with the water without hurting them.

The automatic flashing lights (which are situated close to the crops) will deter the birds, making them scared.

This method to protect corns from birds can be effective, but if you have big corn field and you need more than one fixture, then you will have to spend a fortune. 

Final Conclusion

Dealing with birds isn’t easy, but it’s not impossible either.

As long as you know the proper ways on how to protect corn from birds, you should be able to tackle the issue quite effectively.
