Why Do Love Birds Fight Each Other? (Answered! + FAQs)

Love birds can be really loving but they can be really aggressive to the point of attacking each other!

As I was really curious as to why they do this, I did my own online research and came up with a definitive answer!

Here’s what I found:

Love birds attack each other because they get quite territorial and agitated when they are in the same cage for too long. In many cases, lovebirds of the same gender mistaken to be a bonded pair get territorial and attack each other. Attacks are most common among female lovebirds and Peach-faced Lovebirds.

Love birds actually attack each other due to multiple reasons. If you read on in this article, I will cover more details on the reasons and more answers to FAQs that you may need to be answered. Let’s go!

Why Do Love Birds Attack Each Other? (Full Answer)

Chances are, if you’re reading this, then you’re probably really out of your wits because your lovebirds seem to be fighting non-stop. No worries, I’ll be helping you understand this behavior!

Here are 3 reasons why love birds attack each other:

1) Love Birds Are Very Territorial

Firstly, you need to understand that lovebirds are extremely territorial birds. In fact, all birds are extremely territorial where they defend their spaces in the wild.

Despite being tame for many years by humans, lovebirds still retain their territorial instincts, just like dogs that bark when neighbors walk past!

Here’s how bad it can get:

Birds in the wild typically will defend their territorial spaces using the birdsongs and sounds that they make. These warn other potential rivals to keep away from their spaces and their mates.

In the same way, your lovebirds may still maintain this behavior especially when they see another lovebird of the same gender.

Oh, chances are, your bird are likely to be throwing things around when they are feeling very territorial. I wrote an article on that behavior here. Do check it out as I go deep into the details behind it!

2) Your Paired Lovebirds Are Both Female

Okay, here’s the crucial part that many lovebird owners miss out on: Lovebirds are often mistaken between their genders because they look so similar!

Many pet shops just assume that a pair of birds are male and female without confirming it with their DNA.

Get this: A DNA test, known as an Avian DNA Sexing Test, is the only way you can tell a lovebird’s gender with high certainty. Guessing only leaves room for error!

Why is this so important? This is because lovebirds of the same gender are more territorial and will attack each other with more ferocity, and sometimes to the point of death.

This is particularly seen between two female lovebirds that have been mistaken for a male-female bonded pair for the longest time, only for their owners to find out they aren’t when they fight to the death when they hit sexual maturity.

This is known as being sexually monomorphic, this means male and female birds look the same!

And it’s also really easy to get your love birds/other pet birds tested for their sex these days. In fact, you can actually order an Avian DNA Sexing kit right from Amazon!

I really recommend that you get your bird’s DNA tested, either through this kit or other means!

In other cases, even when the lovebirds you have are DNA-confirmed to be a male-female bonded pair, they may still fight occasionally. This can purely be due to birds being highly territorial creatures, even within their own pair.

Think of it as some ‘space’ needed between partners in a relationship or marriage. Birds also need some ‘space’. Another possible reason is that when lovebirds successfully mate, they may be sensitive and become protective of their chicks.

Okay, other than early prevention, how can you stop the fighting between birds?

A simple and effective strategy that many bird owners from forums agree on would be this: Set up two separate cages to house each of the lovebirds in a pair but place them next to each other.

This allows them to communicate with each other, without any physical contact. This can prevent scratching, biting, and other aggressive behavior, allowing them some ‘space to breathe’ from each other.

3) Your Love Birds’ Nesting Behavior Is Stimulated By The Environment And Routines

Earlier I mentioned that love birds were very territorial. That’s actually because it’s a natural instinct to begin nesting behavior and protect their nest.

A bird’s environment can really affect how cranky birds can get. Let me give you an example. When given toys, paper, or even cardboard boxes to shred, love birds can get very consumed by their nesting instincts.

This is because paper shredding is associated with birds looking for items to use for their nest, a type of nesting behavior. This results in them being in a more feisty mood/temper that makes them more likely to bite other birds in their area or even humans.

Check out another article I wrote here about whether birds eat paper:

A love bird’s routines also plays a great part in its propensity to bite or fight.

Keeping a proper routine in feeding, playing, or uncaging your lovebirds is very important! Being late or missing a timing can cause birds to act up, as they may feel stressed by circumstances they cannot change.

How Do I Know If My Lovebirds Are Fighting?

Lovebirds often fight by biting, nipping, and pecking at each other’s feet and beaks. Lovebirds usually fight when they are arguing over food, territory, or simply if they are aggressive to another bird of the same gender. Female lovebirds are more likely to fight with other female lovebirds than male lovebirds.

However, if lovebirds are gently approaching each other and rubbing their faces against each other, then they are not fighting.

Lovebirds also tend to do gentle nips with each other to show their affection. Knowing how to tell these apart takes practice!

Here’s a video example of lovebirds fighting:
