Reasons Birds Chase Each Other
1. Protecting Territory or Nest
One of the reasons for birds chasing each other has to do with protecting their area.
Some birds will live in flocks and can set up in a part of the setting that is conducive for growth. This can include being close to specific food sources or making sure they are not in range when it comes to potential predators.
While all of this is true, it is still possible for other birds to come into the territory. This is when a bird will perk up and become aggressive.
Birds will not like the idea of having another bird come into their region to use the same resources. This leaves less for them and that is the last thing they are going to want outdoors.
In fact, this behavior can also occur with pet birds.
Pet birds will become weary of another bird and might get nippy with them. This can lead to chasing the other bird around.
When it comes to introducing a new bird, it is best to do it slowly.
The older bird needs to know their resources will not get split in half. This is when the aggression starts to come out and the older bird begins to take out their frustration on the newer one.
This can include chasing the other bird around.

2. Protecting Food Source
Protecting the food source is always going to be important for birds.
This is their lifeline and it is something they will protect at all costs. A lot of birds will have specific stashes of food that are placed in their territory. This can even include natural resources (i.e. berries, seeds) that are available close to where they sleep.
If those resources are raided by another bird, it is possible for a chase to begin.
Birds don’t want other birds eating their food.
It is something they will become aggressive about and it can lead to all sorts of issues including fighting.
Birds don’t want a situation where others become aware of where the food is. This can lead to their death through starvation if they are not careful.

3. General Aggression
It is common to look for reasons when it comes to birds chasing each other around.
In some cases, the reason is nothing more than being frustrated with the other bird’s presence. After all, each bird has a personality of its own and this can lead to natural bursts of aggression even within a flock.
As soon as this happens, the general aggression takes hold and it leads to fighting. This can include long periods of chasing each other around.
With pet birds, it’s best to separate the two when this happens instead of letting it spiral out of control.
