Hummingbird Feeder Leaks-3

While some leakage is to be expected from any Hummingbird feeder, excessive leakage is indicative of a poorly constructed nectar feeder and should be avoided.

If your hummingbird feeder is leaking, the problem may lie with a newly purchased defective feeder; in this case, you should switch it out immediately. If the feeder has recently started leaking, it may be because you haven’t been maintaining it. The feeder must be kept full without causing a vacuum to form inside of it.

Operating a hummingbird feeder can be aggravating due to the persistent attempts of the produced sugary-water to seep out.

Since attempting (and failing) to repair the leak on your own would practically nullify your product warranty, you shouldn’t have to put up with that from the start and should instead immediately request a replacement or refund from the seller.

However, if you’ve had your hummingbird feeder up and running for a while and it only just starts leaking, it may be your fault.

When sugary water damages the internal joints of a hummingbird feeder, the resulting leak is not immediately noticeable.

When hummingbirds sip the nectar, it is normal for some of it to drip out of the feeding apertures. This is not a defect.

A glass hummingbird feeder is more likely to leak than one made entirely of plastic, in my experience, because the steel components that are so commonly used in its construction do not form a very airtight seal with the glass.

However, the suction created within a plastic hummingbird feeder might be compromised over time.

Another potential problem is if you keep moving the feeder around while it’s full of honey; if pests like squirrels are responsible for knocking it over, the nectar could spill.

Keep the feeder as steady as you can, and fill the nectar dish to within an inch of the top in the interim; the problem may be due to a malfunction that cannot be fixed without purchasing a new feeder.

It’s possible for even the best hummingbird feeders to leak, however a disc-shaped feeder, as opposed to an inverted feeder, may be less prone to dripping or leaking due to the ideal placement of the lid.

Cause of faulty feeder only

If this is the first time you’ve used your hummingbird feeder, I can tell you with absolute certainty that the reason it’s leaking is because it’s broken.

Failure to properly store liquids, such as the sugar water used to feed hummingbirds in their own nectar feeder, is a common problem with bird feeders in general, but is especially widespread with these types of feeders.

How can you avoid this error that I’ve noticed? Let me simply state that the fact that something is broken doesn’t mean it can’t be mended. A manufacturing issue may have its roots in an initial flaw.

Even well-known companies like Perky-Pet have been known to occasionally sell defective hummingbird feeders that leak.

The body or sections where hummers sip nectar may have a kink in construction, and this is true of both plastic and glass hummingbird feeders.

If your hummingbird feeder leaks the first time you use it, it’s typically because of a lip or bump caused by shipment or damage that went missed at the point of purchase.

Lack of maintenance

Hummingbird Feeder Leaks-2

What you may not know about hummingbird feeders is that this type of feeder is a plain water, no-maintenance hummingbird feeder, but that it must be cleaned of any sugar residue or debris that has accumulated inside it.

Hummingbirds, as well as other birds and vermin like squirrels, will frequently assault a nectar-filled feeder, bringing with them both sugar and dirt.

Over time, as the sugar accumulates, the feeder’s sugar will grind down the joints where the pieces clip or screw together. As a result, what was once an airtight seal that kept liquids where they belong is now dripping or leaking.

A little leakage isn’t a big deal right now, but it could be an indication of a feeder problem that will get worse with time.

If your hummingbird feeder is leaking, removing it and giving it a thorough cleaning is the first step you should take toward restoring it. This will allow you to remove any sugar or debris that may have accumulated in the feeder’s internal or external assembly joints.

Hummingbird feeders should be checked and cleaned at least twice a week to avoid leaks.

Not performing routine maintenance on your hummingbird feeder could be the root cause of its persistent leaking.

Feeder not kept full

If you didn’t previously know, the suction that keeps nectar in a hummingbird feeder from spilling can be broken if the feeder isn’t kept full with nectar, either before use or when it’s being used.

Hummingbird feeders use a vacuum, which is created by placing the nectar bottle in a larger container with a lid that seals off the air. Once air is let in, the vacuum can no longer prevent the nectar from leaking out.

It is also possible to overfill a hummingbird feeder, which will result in a poor vacuum seal.

A hummingbird feeder with a broken seal shouldn’t leak, so the problem must be with the feeder itself.

If your hummingbird feeder’s manual doesn’t specify otherwise, fill it to within an inch or so of the top.

A hummingbird feeder’s seal may be compromised if the nectar reservoir slowly empties over the course of many days. There is little that can be done at this time save from providing more frequent nectar refills.

Unstable hummingbird feeder

To keep nectar from spilling out of the feeding ports of an upside-down bottle hummingbird feeder, a vacuum must be created.

Don’t touch the hummingbird feeder till it’s time to refill it, but do your best to keep it full at all times.

Hummingbird feeders can be placed anywhere in the yard, but they should not be unhinged during use. Doing so could cause the suction to be disrupted and drive away the birds you’re trying to attract.

A hummingbird feeder’s vacuum seal is crucial because nectar might easily leak out of the sipping holes if the feeder is knocked over.

Leaking hummingbird feeders can also be caused by the wind, which causes the feeder to shake and swing.

To prevent the feeder from toppling over in high winds, it is recommended to secure it to a nearby branch or bracket using rope or wire.

In my opinion, the disc-shaped feeders are the most leak-proof option for hummingbird lovers, but it’s important to note that even the best feeders may eventually develop a small leak or drip here and there.

No stopping leaks or drips

Hummingbird Feeder Leaks

The heavy use at the feeding ports by hummingbirds could be the cause of the leaking, rather than a problem with your hummingbird feeder.

Because of the potential interest from other bird species, the sugary water could end up being more of a nuisance to other species than the hummers it was meant to attract.

You’ll likely notice some dripping right away, which is to be expected given that the feeder will inevitably leak a little nectar onto the outside even after regular use.

The hummingbird feeder may be of poor quality and leak because of this.

While attracting beautiful hummingbirds, hummingbird feeders may sometimes make a sticky mess on the outside and the ground below. Some people might not even notice it, but if water leaks or simply drips into the ground just below the feeder, it could attract ants.

If the sweat nectar may remains accessible on the exterior of the feeder due to leaks or drips, then bees will continue to congregate around the feeder.


If your hummingbird feeder seems to be leaking, it may be due to a defect in the feeder itself; in this case, the only cure is to purchase a new one.

Problems with feeders typically arise because of lax production standards, which leaves consumers with malfunctioning feeders. Don’t waste time trying to make it work if you intend to return it to the seller and get a refund or replacement.

If you’ve had your hummingbird feeder for a while with no leaking difficulties up until now, it’s possible that you’re to blame for the leak.

The reason for this is that if you don’t regularly clean and maintain your feeder, sugar and dirt residue will accumulate and find their way into the feeder through any available cracks or openings.

Leaks can occur if air is allowed into a feeder that is supposed to provide a vacuum. When a crack is created by dirt or sugar, nectar can be seen trickling through it.

While it’s unlikely that your Oriole or Hummingbird feeder will spring any large leaks, the vacuum seal will break if you accidentally poke a hole in it.

The stability of the hummingbird feeder is paramount when it is in use; if necessary, use rope or wire to keep it from swaying or rocking in the wind.
