Hummingbirds are some of the most beloved and fascinating creatures in the animal kingdom. Their tiny size, vibrant colors, and remarkable ability to hover and fly backwards make them a source of wonder and interest for many people.
But beyond their beauty, hummingbirds also have a unique behavior that has been studied by scientists for years: they can be surprisingly territorial.
Why are hummingbirds territorial?
Hummingbirds will defend their territories for a number of reasons.
Breeding
Territorial behavior is most often seen during the breeding season, when males will aggressively chase away any intruders that enter their territory. The size of a hummingbird’s territory can vary greatly depending on the species and the availability of food sources. They must protect it to ensure the successful breeding and raising of the young.
Predation
Hummingbirds will often fiercely defend their nests from predators and other birds that may try to steal eggs or young.
Competing for nectar sources
Hummingbirds are fiercely competitive when it comes to nectar sources. Male hummingbirds will frequently stake out a patch of blooms and defend it with great vigor, as flowers only last for a limited time.
Flowers produce nectar, which is rich in sugar, to attract these creatures. In turn, the birds and insects pick up pollen from one flower and carry it to another, helping the plant to reproduce. So, a territorial hummingbird is beneficial for both the bird and the flowers; the birds get a reliable source of food, while the flowers get pollinated.
In addition, not only do they provide pollination services, but they also help spread genetic diversity among plants by carrying pollen from one flower to another. This helps ensure that plants can continue to thrive in their environment over time.

How do they show territoriality?
Hummingbirds use a variety of methods to defend their territory.
- performing aerial displays, such as dive-bombing or chasing away intruders
- making loud vocalizations
- aggressive postures to ward off competitors
- spreading its wings to appear larger and more intimidating
- fighting with one another over resources by using their bills to peck
Dealing with aggressive hummingbirds
In some cases, hummingbirds have been known to attack humans who get too close. Fortunately, there are several ways to stop aggressive hummingbirds.
Providing multiple feeders in different locations so that individual birds have their own space. This will help reduce competition between the birds and make it easier for them to find food without having to fight with one another.
Additionally, providing plenty of natural nectar sources, such as flowers or shrubs, can help reduce competition as well.
Finally, using feeders with perches can help keep the birds away from each other since they won’t be able to hover around the same area while feeding.
By following these tips, you and your family should be able to enjoy watching these feathered friends without worrying about aggression or territorial disputes.
Final Thoughts
Understanding territorial behavior can help us better appreciate and protect these amazing creatures. If any bird acts aggressively towards you, the rule is simple. Just move away. All birds will act to protect their young, and hummingbirds, despite their tiny size, are no exception. Batting away an angry hummingbird is likely to just hurt it. Leaving it alone is always the best idea.

FAQ
Increasing the availability of food is the best way to stop competition between hummingbirds. Rather than having 1-2 feeders, try having at least 6.
Very. Hummingbirds have proportionately large brains, and they use them to memorize the important features of their territory.
Yes, small raptors like kestrels and kites will take hummingbirds, if they can catch them.
It takes a lot of energy to keep those wings beating so fast. Hummingbirds need to eat every 15 minutes so if you see them flying around, the chances are they are looking for food.
