Hummingbirds are fascinating creatures to watch due to their size and speed. They flap their wings at an incredible rate of around 50-80 times per second, earning them their name. However, one behavior that is commonly seen among hummingbirds is their tendency to chase each other. But why do they do this? Let’s find out.

What causes hummingbirds to chase each other?

Hummingbirds have a variety of reasons why they chase each other. One of the most common reasons is for mating purposes. Male hummingbirds are very territorial, especially during breeding season, and they often chase other males away from their designated territory. This behavior is intended to scare off any potential rivals who may threaten their chances of breeding.

However, not all chases are for mating purposes. Sometimes, they chase each other to establish dominance. According to scientist and hummingbird expert Gregor Yanega, “Hummingbirds chase each other around to sort out who dominates control of key food resources, such as feeders of nectar-bearing flowers. The winner gets the prize, while the loser has to settle for the scraps.”

Another reason for hummingbirds chasing each other is due to their aggressive nature. Hummingbirds are highly aggressive birds and they defend their feeding areas vigorously. According to the Cornell Lab of Ornithology, “Male hummingbirds often claim the best feeding territories and will vigorously defend them, sometimes chasing a competitor long distances before returning to their perch. Sometimes, the pursuit is over in seconds; other chases can last for minutes.”

Is it a territorial thing?

Yes, hummingbirds chasing each other is often a territorial thing. Male hummingbirds are known to be highly territorial, especially during breeding season. They defend their territory from other males to ensure that they have access to all the resources they need. This includes food, nesting sites, and potential mates.

According to research published in the journal Behavioral Ecology, “Male rufous hummingbirds regularly occupy territories during the breeding season, where they defend resources essential for successful reproduction, such as nesting and feeding sites, and appropriate mates. Males that fail to defend territories risk reduced reproductive success.”

Do only male hummingbirds chase each other?

No, both male and female hummingbirds are known to chase each other. However, the reasons for chasing may differ between sexes. Male hummingbirds often chase each other to establish dominance and to protect their territories, while females may chase males away from their nesting sites or food resources.

According to the Cornell Lab of Ornithology, “Females may also be aggressive around nesting sites, possibly to protect their young or prevent another female from taking over her nest. Female hummingbirds are known to defend feeding territories and may aggressively attack intruders, including other females.”

Overall, the behavior of hummingbirds chasing each other is complex and multifaceted. While much of the chasing behavior centers around territoriality and mating, there may be other reasons for chasing as well.
