The Dawn Chorus: Why Do Birds Sing in the Morning?
What Is the Dawn Chorus?
The dawn chorus is a natural event that happens every morning while most of us are still asleep. It’s an orchestra of birdsong; nature’s get-ready-for-the-day-ahead cacophony of sound.
Apart from a few nocturnal species, birds stay quiet and sleep through the night. As dawn breaks, before the first rays of sunlight pierce the darkness, a solitary bird will begin to sing. In the following few minutes, a couple more join in. Gradually, hundreds more join the chorus, and the result is magical. By the time the sun has fully risen above the horizon, the show is over. If you want to experience this event for yourself, be prepared to wake up very early. A complete dawn chorus rarely lasts longer than 30 minutes.
It’s too soon in the day for most humans to be out and about, so there’s very little traffic noise. The birdsong is clear and easy to hear. It’s a good time to learn to distinguish between the calling notes of different species.

Prepare to Listen to the Dawn Orchestra
- For the dawn chorus, your ears are your primary tool.
- Check what time sunrise is expected and plan your outing in advance.
- Plan to start listening to the chorus at least one hour before sunrise.
- Wrap up warm as night temperatures are usually colder than daytime.
- Take a torchlight so that you don’t trip over tree-roots on the way to your observation point.
- Once in position, stay still and keep quiet.
- Listen, don’t talk or whisper.

How Do You Know Which Bird Is Singing?
If you’re a novice birder, don’t get too worried at this stage about which bird sings what. Being able to recognize individual birdsongs comes with experience. If you want to understand different species, you’ll need to show patience and learn to actively observe.
Ideally, go out with an experienced birder to hear your first dawn chorus. If that’s not possible, before your trip into your backyard or further afield, take a look at a few books and videos about birds local to your area.
The videos below show some of the common species found in backyards in North America and the UK. I also recommend you download a to refer to when you’re out and about. But most of all, enjoy being outdoors and watching the sun rise as hundreds of birds sing their hearts out. bird song app

Why Is There a Dawn Chorus?
There are many theories about why the dawn chorus occurs. Here are the three most common ones.
Birds are territorial, and they protect their domain by calling out to their neighbors. By singing loudly they warn others that they are dominant, and have first choice in the food sources in this location. Prime real estate for our feathered friends means a ready supply of food, water, and nesting locations. This means they defend a territory that supports insects, seeds or small invertebrates, depending on their menu of choice.
Birdsong is an indicator of the health and age of a bird. A female wants to select the best genes for her offspring, so choosing a mate on the basis of the fluency and musicality of their song is a good policy.
Quietest Time of Day
On a purely practical level, dawn is the quietest time of day. The birds are awake, but it’s too early to start hunting for food as light levels are still low. The best time to make any announcements is when your audience can hear you, and has not yet left for work; hence dawn is a good time to pick.
International Dawn Chorus Day
The first Sunday in May each year has been designated International Dawn Chorus Day. The last one was on Sunday 3rd May 2020, and the next one will be on Sunday 2nd May 2021.
It’s “a celebration of nature's symphony. All across the world people rise early to revel in the sweet sound of birdsong, from rattling wrens in Rotherham to crooning cowbirds in the Caribbean.” Wildlifetrusts.org
The date has been chosen because there are still enough birds singing to make it worth your while to get up early to hear them, and the nights are not quite so cold as they were earlier in the year. Many wildlife groups organize events on or around that Sunday each year. It’s a nice way to learn about nature and meet like-minded people. Check out the websites below a few weeks before the date to find out what’s planned in your area.
Why Do Birds Stop Singing?
The wake-up chorus lasts for about half an hour each day. The best time to hear it is in the spring. In the summer, there is a noticeable reduction in all birdsong activity, and this applies to the dawn chorus too. Some people worry that something has happened to the birds, but this is a normal change in behavior.
Does the Season Affect the Amount of Birdsong?
The peak breeding season is over by the end of May in the Northern hemisphere, and so the birds have less need to defend territory or show off to potential mates. Natural behavior patterns synchronize with seasonal weather to maximize food availability and ensure species survival.
When Does the Dawn Chorus Start and Stop?
The timing of first-light or break-of-dawn depends on the season and your location. Birds are more vocal during the mating season, so whichever months are Springtime for you are the best ones to listen out for the dawn chorus.
