Hummingbirds are known for their unique ability to hover in midair and their beautiful, iridescent plumage. These tiny birds are a delight to watch as they dart around flowers, drinking nectar. However, you may have noticed that hummingbirds also make chirping sounds, especially when they notice you nearby. So why do hummingbirds chirp at humans? There are a few key reasons.
Territorial Signals
One of the main reasons hummingbirds chirp is to communicate territory. Hummingbird species are highly territorial, especially when it comes to favorite feeding areas. The males in particular will defend flower patches, feeders, or other prime nectar sources from intruders. When a hummingbird sees a potential threat, like a human, near their territory, they may start calling out in warning. This abrupt, squeaky chirping lets intruders know that this spot is occupied. It’s a way for the little birds to signal “back off” from their prized food source or perch.
Mating Calls
In addition to marking territory, male hummingbirds will use chirping as a way to attract females during breeding season. The males perform elaborate courtship dances, flying in loops and dives while chirping repeatedly. This “song” is a key part of their mating ritual. The unique chirps allow the female hummingbirds to identify males of their own species. So that melodious chirping you hear near your feeder may well be a male hummingbird’s attempt to catch the interest of potential mates.
General Excitement
Hummingbirds also chirp when they are feeling particularly energetic or excited. The birds make a wide variety of sounds, and some of their chirping is simply an expression of liveliness. Just like songbirds singing happily at dawn, hummingbirds will vocalize exuberantly when visiting a favorable feeding ground. The ready availability of sugary nectar provides a burst of energy, which the birds channel into chirping. Their chirps and squeaks while feeding are a sign of pure delight.
Warning Signals
Hummingbirds may also vocalize to point out potential threats to other birds. Their chirping serves as an alarm call for danger. Research shows that broad-tailed hummingbirds use at least five distinct chirp sounds to convey different messages. One of these sounds is apparently a warning signal reserved for potential predators. When a broad-tailed hummingbird makes this particular noise, other birds in the area become watchful and cautious. The hummer is letting its compatriots know something risky is nearby, like a prowling cat.
Curiosity About Humans
Many experts believe that hummingbirds chirp at humans out of curiosity. Hummingbirds have excellent memories and will remember individual people who have fed them or posed no threat in the past. When you hear a hummingbird squeaking near you, it may simply be the bird’s way of checking you out. The hummingbird is likely confirming your identity and communicating that you are recognized. This helps explain why some hummingbirds will boldly chirp when humans approach, while others flee in fear. Those that stick around and chat are just being friendly with familiar caretakers.
Invitation to Provide Nectar
Along with curiosity, hummingbirds may chirp at humans in hopes of getting fed. The birds quickly learn to associate their human caretakers with food. A nice nectar blend provided in a feeder is much easier for hummingbirds than searching flower by flower for sustenance. Intelligent hummers realize that chirping at people captures their attention and may get rewarded with readily available nectar. The birds’ chirps essentially say “Hey, over here! Time to feed me!” Once the hummingbird has you trained to provide food whenever they call, they’ll continue this signaling behavior.
Responses to Other Sounds
Interestingly, hummingbirds appear capable of modifying their vocalizations in response to sounds in their environment. Researchers have found that the birds will change the frequency and pattern of their chirping based on background noise. This suggests that hummingbirds may chirp when humans talk or make noises as a way of replying. The hummers want to be heard, so they adjust their sounds to stand out against any din. The more noise you make, the more it seems to stimulate chirping from nearby hummingbirds.
Conclusion
In most cases, hummingbirds chirp and squeak at humans because they either want to communicate with us or simply see us as an interesting curiosity. Of course, interpreting the exact message behind a hummingbird’s chirping is impossible. But paying attention to the context can help provide clues to their motivation. With some species known to make distinct threat calls, territorial claims, mating songs, and feeding demands, the nuances of hummingbird vocalizations are intriguing. These delicate birds have a surprisingly complex language that we are only beginning to understand. So take the time to appreciate hummingbird chirps for the wonder of nature they represent. The birds are actively interacting with you in their own unique way!

Decoding the Different Types of Hummingbird Chirps
Hummingbirds produce an extensive range of chirps and squeaks to communicate different messages. Here are some of the most common chirp types and what they mean:
Short, repeated chirps
A brisk series of 10+ rapid chirps often signifies an alarm call or warning. The hummer is on high alert about a potential threat.
Single loud squeaks
One strong, abrupt chirp is typically territorial. The bird is claiming its feeding ground and challenging intruders.
Airy, twittering chirps
More melodic, complex vocalizations are used in courtship displays by amorous males.
Drawn-out squeaky chirps
Long, whiny chirps are begging calls from young birds asking their mothers for food.
Soft, variable chirps
These gentle chirps are a sign of curiosity or recognition between a hummingbird and human companion.
Staccato buzzing
Low, rhythmic buzzes indicate a competitive chase between males defending areas.
High-low-high chirps
This signature chirp functions as a feeding call, requesting nectar from caretakers.
Louder chirps at dawn/dusk
Hummers vocalize more before nesting down or waking up for the day.
What Do Hummingbird Chirps Sound Like?
Hummingbird vocalizations are as diverse as the birds themselves. Here are some ways to describe hummingbird chirp sounds:
- A short, high-pitched squeak, like a tiny hiccup
- Rapid beeping, similar to a smoke detector alarm
- Metallic clicks and buzzes
- Faint twittering
- A sharp “chip” tone
- Whiny peeps
- Staccato trills
- Frenzied, robotic chattering
- A quick squeal on one sustained note
- Soft or loud chirping
- An accelerated series of sweet peeps
Of course, the best way to distinguish the varied chirps of hummingbirds is to listen closely to these vocal acrobats in action!
Which Species Are the Most Vocal?
While all hummingbirds use chirping to some degree, a few species are known for being more vocal and melodic:
- Anna’s hummingbird
- Costa’s hummingbird
- Allen’s hummingbird
- Rufous hummingbird
- Broad-tailed hummingbird
- Calliope hummingbird
- Black-chinned hummingbird
Researchers have recorded the Anna’s hummingbird producing at least 13 distinct vocalizations. Male Anna’s put on impressive midair courtship displays accompanied by complex singing. Costa’s hummingbirds also vocalize extensively with sharp squeaks and whistles.
In general, hummingbird species found in western North America appear to be the most vocal and offer great opportunities to appreciate hummingbird chatter!
Interpreting Hummingbird Vocalizations
Hummingbirds don’t just randomly chirp for no reason. Their diverse squeaks, peeps, whistles, and buzzes all serve a specific purpose. Here are some tips for understanding what a hummingbird is communicating when it vocalizes:
- Note the context – is the bird defending a feeder, interacting with a mate, responding to a threat, etc?
- Identify unique chirp characteristics – rapid, musical, buzzing?
- Pay attention to changes – did the tempo or pitch shift?
- Observe body language – agitated movements, wing displays, flocking?
- Consider species tendencies – is the bird a known vocalist?
- Compare to past chirping encounters with the same bird.
- Look for any behaviors prompted by the chirping – leaving, approaching, fleeing.
While we can’t know exactly what a hummingbird is saying, familiarity with particular birds and practice identifying their various chirps helps reveal deeper meaning.
