Why Do Birds Chirp At Night? 7 Reasons

The last thing anyone wants to hear when going to bed is chirping noises outside their window.

It’s a common behavior for most birds. They sometimes do this at night for territorial reasons. Other times they get simply confused. When they chirp at night, it’s because they have a specific purpose in mind. They use their sounds to call for other birds and animals. Most of the time, it’s because they want to satisfy their needs and desires.

However, there’s a lot more to it. It’s only logical for you to think that nocturnal birds would make up the majority of the sounds you hear at night. Not just nocturnal, but diurnal birds also tend to be vocal at late hours. Keep reading to find out more reasons and details behind this particular behavior.

7 Reasons Why Birds Chirp At Night

To learn why birds chirp at night, we must understand why they chirp in the first place. Just know that it isn’t because they’re feeling musical or in a good mood. It depends on a variety of reasons, but essentially, it narrows down to survival. Here are the many reasons why birds chirp at night!

Marking Territory

Birds can get very territorial after finding a suitable area. They won’t give up spots that are going to help them survive better.

Food, water, shelter, and nesting places all make up an ideal place for survival. Once they find a place that fits all the criteria, they will hang on to it for dear life.

They chirp loudly to mark their territory. This lets the surrounding birds know that someone else has claimed the territory. Sometimes they will even negotiate privacy boundaries through singing!

If some bird tries to invade territories that do not belong to them, you can expect to hear lots of noises as the alphas try to out muscle each other.

Light Pollution

Birds chirp in the middle of the night when they are simply confused. Thanks to the continuing growth of towns and cities, urban streetlights and light pollution are bound to harm their sleeping habits.

It messes with birds like American robins into thinking that it is dusk, while in reality, it’s just midnight. They are not intelligent enough to tell the difference between natural daylight and artificial light. As a result, they will be active and start singing instead of resting.

Attracting Mates

Most birds’ mating rituals include chirping and singing. During the springtime, they tend to be extra loud as it is the breeding season.

Male birds sing to attract females into mating with them. They are very vocal during the night as well. If you hear a lot of chirping in your area, chances are a couple of little birds are on their way!

Danger Calls

Birds react to danger in the same way that humans do. If they sense a threat, such as loud noises or the nest shaking, they will become alarmed and begin to sing.

As a result, if one starts chirping, others will join the cause, much like the dawn chorus. They also make loud noises whenever a predator attacks to signal the other nearby birds to steer clear. Surrounding members respond to the warning, causing a ripple effect of noise.

Contacting Flocks

Birds sing in unison when migrating in flocks. Flight calls are the term for these sounds. Most migrating birds travel at night because the moon and stars help with their navigation. So, you are most likely to hear these calls at night.

They also use chirps in their flying calls to communicate with one another. It’s a traveling strategy to keep any member of the flock from getting lost. When they are in a new place, it helps them gather all in one spot and stay secure.

Newborn Birds

Hatchlings and baby birds are helpless, defenseless creatures. Their parents must provide regular care for them. So, why do nestlings cry out loud at night?

Just like human infants, baby birds will also cry to let their parents know that they are hungry and need to be cared for. The begging of chicks in the nest is one of the most relentless noises you’ll hear from birds.

Parents spend the majority of their day outside the nest gathering food. Loud crying is the newborn birds’ way of calling their parents to return home with food. So, it’s only natural to hear persistent chirps in the middle of the night. The noises could mean that the nestlings are hungry, thirsty, excited, cold, scared, or sick.

Source Of Food

When food is available, birds become pretty thrilled and create lots of noises to express their happiness. If they find a new food source, its members usually announce it to the flock. When a few birds gather around a fresh food supply, they squawk and fight as they compete for shares.

In addition, male birds with food are more likely to be rowdy. This is regarded as an announcement that they can provide for the ladies. It’s also possible that their extra energy from the meal is causing them to sing.

Birds That Chirp At Night

As it turns out, there are a lot of birds that chirp at night. Take a look at some of the most common birds that chirp at night.

Barred Owls

Whenever you hear a nocturnal bird, the first name that pops into your head is owls. During the breeding season, you may hear a pair of barred owls calling to one another as well as singing throughout the night. Owls do not chirp but emit a unique hooting sound instead.

American Robin

Though they are mainly active during the day, American robins have been the most affected by city life. Artificial lighting and light pollution can easily deceive the robin into thinking it is still daytime or dusk. This is the main reason they sing at night.


The most commonly heard birds during night hours are arguably mockingbirds. They’re especially spotted in urban areas.

Their calls are typically lengthy for chirps or a melody. It’s most likely a mockingbird if you have heard a non-stop stream of different bird calls late at night.

Eastern Whip-poor-will

Although you won’t be able to spot a whip poor hill as they are excellent at hiding themselves, you will be able to hear one at midnight.

They can sing for several minutes at a time late at night. Interestingly, their name comes from the sound of their chirping.

Black Rail

These birds are far more territorial than others. You will hear black rails chirping in the middle of the night with a ‘ki-krrrr’ sound.

The noise makes them sound aggressive, which serves as a territorial warning to nearby birds. Here is another related list of birds that commonly sing and chirp at night.

It’s always fun to learn something new about birds and their behaviors. Even though you can’t do much to stop them from chirping at night, you can at least observe their habits now. This could be warnings of danger, territorial disputes, calling for mates, or socializing with the flock. We have also looked at some of the most common night-noising birds.

So, the next time you listen to loud bird noises during bedtime, it should no longer be a mystery to you.



What Times Of The Day Are Birds Most Active?

The majority of the birds are active at dawn, predusk, and early morning. But it might vary from bird to bird.

To get the most out of your birding experience, you need more than just a set of binoculars and some spare time. You need to be aware of the perfect timings to step out as well. Most birds can be seen during the following hours:


Do not confuse dawn with transition times. Dawn usually starts 72 minutes before sunrise. If you want to hear the sound of the earth awakening, dawn is the best time. Because at this time, most birds sing in chorus.

In North America, the dawn chorus starts when Robin and Lark’s species start singing. And later on, Sparrows and Blackbirds join in. The low or dim light at dawn triggers them to sing harmoniously. Also, at such low lighting, they cannot go out to hunt so they tend to sing.

Spring dawn is the best time to experience the dawn chorus at its best. Because the temperate climate at that season gathers a variety of diurnal species to sing. So it is the best time for you to join their melodious concert free of cost unless you are birding at a bird park.



Predusk is that short moment just before dusk. It is not the darkest phase of twilight. And generally, predusk starts 30 minutes before the sunset. To diurnal birds, this is the best time for murmuration and avian foraging. So at predusk, you can see a flock of birds, especially the long-billed American Woodcock.

If you are lucky enough, you will get to see some nocturnal species flying at predusk. Basically, they are the predators the diurnal species try to be safe from by forming murmuration. It forms when hundreds to thousands of starlings swirl across the sky. You can go near cliffs, woodlands, or reed beds to enjoy an aerial dance in the beautiful shape-shifting clouds.

At predusk, most birds fly around in search of roosting sites where they can nestle together for warmth. Such a flock of birds can attract predators like Falcons. But it is not easy to attack or single out one bird from a whirling group. So during the murmuration, the starlings swoop, twist, and turn to keep the predators from attacking.

The diurnal species tend to spend the maximum hours of the night without eating. Given the fact that they need to devour as much food as possible before returning to their roosting places, they go foraging or in search of food at predusk. Sometimes they forage at this time to store food for the growing hatchlings.

Transition Times

At transition times the day starts changing into the night and the night into the day. Simply put, this is the time during the sunset or sunrise. It lasts for a few minutes. Diurnal birds tend to stay active at this time mostly for singing in chorus and migration.

The singing at sunset or sunrise is subtler compared to the dawn chorus. The House Sparrows, Robin, and Willow Warbler start a subtle chorus.  So if you are up for a subtle chorus coupled with Wood Pigeons crooning, birding during this time is a good choice.

Transition times radiate celestial cues that help the migrating birds to establish their migratory direction. Also, the pattern of sunbeams at this hour is a good cue to identify the direction or roosting site.

Throughout the October days, you can notice these active migratory visitors, specifically Warblers or Blackcaps. You can watch them from open ground, cliffs, or rooftops. But if the weather is stormy, they might not stay active or migrate at these times.


Early Morning

A lot of birds seem to have taken the saying “early birds get the worms” too seriously. So they come out of their roosts early in the morning. They tend to forage more at this time compared to the predusk. Because at this hour, the ectotherm bugs are easy to find.

Have a look at your grassy or dessert-like yards. That is where the early birds come mostly to look for food. The more a yard looks like a natural habitat, the more species will be active there. If a yard or garden has a seed tray, it will attract more birds.

The ground-feeding birds like Sparrows or Quail use their feet to scratch seeds or other food from the ground. But the Warblers and Chickadees species fly from branch to branch or leaf to leaf throughout the morning to pick up food.


Mid Afternoon 

The time between 2 to 4 is mid-afternoons and most birds like to sunbathe at these hours. Especially the Blue Jays, Doves, and Pigeons. They can sunbathe on the rooftop, ground, or on a tree branch where mid-afternoon sun rays can reach without any obstruction.

At this time, you can notice most birds are engaged in different movements as if a good yoga session is going on. Some of them are facing their backs towards the sun to soak up some warm sunray. Whilst the others spread their tail and stretch wings on the ground.

Birds drink water throughout the day. But during the scorching heat, they are more active near the water sources. If you are in a temperate region, you might observe some Hummingbirds or Sunbirds drinking nectar in the mid-afternoon.

Why Do Birds Stay Active At Specific Daytimes?

It seems that birds do not prefer to be couch potatoes. So they smartly plan and execute different activities at different times of the day.

They maintain specific times because it gives them few advantages. Below are the reasons why birds stay active on specific daytimes.

Courting And Marking Territory 

Birds are most active at dawn chorus because it gives them the ideal environment for courting or attracting other potential mates. And it also gives them the advantage to send clear signals to defend their territory.

At dawn, the air currents are less active and the traffic or insect buzzes are less prominent. So this ambient helps their chorus to reach far away. And the chorus attracts other mates or advertises their strong presence in that territory.

Predators Are Away

During the early morning, predusk, and transition times the raptors or predators do not stay active. It gives most diurnal species the advantage to go foraging without any potential threat.

Even domestic or wild cats, snakes, or animals try to attack diurnal small birds.




4. Are birds that chirp at night disrupting their sleep schedule?

Not necessarily. Many birds that sing at night are naturally nocturnal, so this is part of their normal routine. It’s like their version of a late-night talk show.

5. Can city lights affect bird chirping at night?

Indeed, artificial lights can confuse birds into thinking it’s daytime, leading to more nocturnal chirping. If birds start singing in the middle of the night, it might be because they’ve mistaken streetlights for the morning sun. Talk about a case of mistaken identity!

6. Is it normal for birds to chirp all night?

While it’s normal for some species, it’s not for others. If a usually diurnal bird (active during the day) starts chirping all night, it could be due to disturbance or confusion caused by artificial light, or they might just have a lot on their mind.

7. Can I do anything to stop birds from chirping at night?

While it might seem annoying, especially when you’re trying to sleep, it’s important to remember that birds sing for survival. You can try using earplugs or a white noise machine to drown out the noise. Or you could try learning their song and consider it a free nightly concert!

8. Is a bird chirping at night a bad omen?

No, birds chirping at night is not a bad omen. It might feel eerie because it’s less common, but there’s nothing to worry about. It’s just nature’s way of keeping things interesting!

9. Do birds chirp more at a certain time of year?

Yes, birds tend to chirp more during the breeding season. So if it’s spring and there’s a lot of chirping at night, it might be birdie date night.
