Waking up to the dawn chorus of birds – one of the natural world’s greatest symphonies – is a joy like no other. It is not surprising that bird-watching has become an increasingly popular hobby.
A simple way to start bird-watching is to buy a feeder, a pair of binoculars and a field guide, and begin watching birds from your window.
However, one of the most rewarding ways to identify birds is to listen to them and learn to recognize their songs.
As an ornithologist and educator, I often introduce students to the intricacies of bird songs, and I have developed some tricks that can make birding by ear less daunting.
Learning to listen
Learning bird songs is the difference between “hearing” and “listening.”
Listening requires full attention and limiting distractions. It means using your ears to pick up different patterns in the sounds that birds make. Every person has the capacity to listen and learn patterns in sound.
If I were to sing “da-da-da-DUM” most people would immediately recognize it as Beethoven’s Symphony No. 5. Alternatively, if I were to play the first few notes or beats of your favorite song, I’m certain you would know what it was and who sang it.
The ability to recognize bird songs uses the same part of the brain you use to recognize songs on the radio – the supratemporal, or auditory, cortex, an area just above the ears where your brain processes language and sound.
When you’re birding by ear, you use the same skills as when you’re recognizing music; listening to sounds, patterns, changes in pitch, in tone and in volume, but in nature rather than in music.
You can do this.
To begin learning to recognize bird songs, select two to three common bird songs that you hear frequently around your neighborhood.
Sometimes there are mnemonics that you can use to help remember the songs. For instance, the tufted titmouse says “peter, peter, peter” over and over. Sometimes it sings it fast, sometimes slow, but always “peter, peter, peter.” Whereas the Carolina wren says, “tea kettle, tea kettle, tea kettle”.
Songbirds aren’t the only birds with helpful mnemonics. Next time you hear a hooting sound, if it sounds like “who cooks for you, who cooks for you all,” that’s a barred owl.
Why and how songbirds sing
Watching the actual bird sing its song is one of the best ways to learn the bird and song together. Find a tufted titmouse and watch it sing “peter, peter, peter,” and you will remember it forever.
Try going out into the woods with your binoculars and following unfamiliar sounds.
Many species make unique sounds as they sing, chirp, hoot, screech or whistle. They vocalize like this for a variety of reasons – to attract a mate, defend a territory, alert other birds to threats, or to locate other individuals to form flocks or groups.
Songbirds, such as the tufted titmouse and northern cardinal, are the group that ornithologists associate most with complex songs. They tend to have multiple notes and patterns that change in pitch and speed, rather than simple one-note or two-note calls.
These birds have a unique voice box called the syrinx, which translates to “double flute” in Greek and allows them to create two sounds at once.
Birds learn their songs in multiple ways.
Songbirds are born with an innate “template,” which tells them the basics for the song to sing. But they also learn from listening to adults. Studies have found regional dialects of birds’ songs and evidence that some birds learn songs from their parents while still in the shell. Sometimes they learn songs from neighbors, who usually end up becoming competitors for territory.
Human activities can affect birdsong
Human behaviors can also affect how birds sing.
Studies have found that, in some instances, background noise can weaken territorial responses in males. And light pollution in suburban areas can prolong singing by up to an hour.
In 1962, scientist and conservationist Rachel Carson wrote the book “Silent Spring” after noticing how quiet the spring had become when the bird migration would normally be underway. The pesticide DDT had weakened egg shells, triggering a sharp decline in many bird populations. Many scholars and historians identify this book as leading to the creation of the U.S. Environmental Protection Agency under President Richard M. Nixon in 1970.
Getting started birding by ear
As you start learning bird songs, technology can come in handy. There are now dedicated apps, such as Cornell University’s Merlin, that can help you recognize bird songs as you are listening to them.
However, human abilities still outperform this technology, so use apps as a learning tool, not a crutch.
As humans, we have long depended on our ability to communicate with each other. I think we relate to birds because they are such vocal creatures too.
Learning their songs is a lifelong endeavor. Once you start tuning into the natural world, you’ll realize that there is something new waiting to be discovered.
