How to Start Identifying Birds by Their Songs and Calls

Part one in our new series to help you build your birding skills鈥攁nd love of birds鈥攂y learning how to bird by ear.

Editor鈥檚 Note: There's a lot to look forward to in spring, including the welcomed hullabaloo of birdsong. The sheer volume of songs and calls to learn can often feel overwhelming for birders, but these sounds offer both an opportunity and a challenge. Follow along with our birding-by-ear series to learn how to use vocalizations to better ID birds. To catch up, check out part 2part 3part 4part 5part 6part 7, and part 8.  

First up, master birder and 探花精选 field editor Kenn Kaufman on why you should give birding by ear a chance, and what you need to get started. (Bonus: You're probably already doing it!)

Shakespeare was a Bard and a birder. Don鈥檛 believe me? Check out Romeo and Juliet. During a secret nighttime tryst, the star-crossed couple argues about a bird they鈥檙e hearing outside the window. Is it a nightingale or a skylark? The question is a matter of life or death: If it鈥檚 the lark singing, that means daybreak is coming, and Romeo must flee for his own safety.

Fortunately, nailing bird IDs doesn鈥檛 usually have such heavy consequences. But for birders, learning to recognize birds by their voices is tremendously valuable. People may speak of 鈥渂irding by ear鈥 as if it were different from normal birding, but it鈥檚 not; it鈥檚 something you鈥檙e already and always doing. In my case, whenever I鈥檓 outdoors or even close to a window, I never stop listening for birds. When my wife, Kimberly, and I got married, for example, I identified eight species by voice during the ceremony. She wasn鈥檛 mad鈥攕he heard and IDed the same birds.

Experts never stop birding by ear, and for good reason: Sound is very often the best way to detect a bird鈥檚 presence. Rails rattling in a marsh, a tanager whistling from the treetops, pipits calling in flight overhead, a Canyon Wren singing from a ravine wall鈥攖hese species can easily go unnoticed if you鈥檙e not listening. In dense surroundings like rainforests, sound becomes even more essential. 鈥淏irding in tropical forests by sight alone is like watching the news on television with the sound turned off鈥攜ou鈥檒l miss most of what鈥檚 going on,鈥 the late Ted Parker once said. (Parker was legendary for by voice.) The same can be said about dense, species-rich habitats here in the states, from wooded swamps to the sagebrush sea.

Plus, for species that are easy to spot but hard to tell apart, voice can be the best clue. Eastern and Western Meadowlarks, dowitchers in winter plumage, and several kinds of flycatchers all fall into this category. To work through these sticky IDs, birdwatchers need to double as bird listeners, too.

Birding by ear can seem daunting when you鈥檙e just getting started, though. A spring sunrise could serve up dozens of different species calling at once. Picking out a single voice from the chorus feels hard enough, but trying to name each singer is downright overwhelming. How will you ever learn them all?

The good news is that you don鈥檛 have to learn them all, especially not right at first. The benefits of birding by ear start to kick in as soon as you learn a handful of voices. Mastering the sounds of one or two species is the key to learning more; as you build up your mental library, you鈥檒l have more practice and more basis for comparisons.

As with other aspects of birding and bird ID, it鈥檚 good to build on what you know. Are there American Robins in your yard or local park? In addition to their rich, caroling song, robins have a surprising number of different calls. Spend some time with them and study their repertoire; the knowledge will be useful practically anywhere you go in North America. Plus, it鈥檚 a method you can repeat with other familiar species.

To speed up the learning process, don鈥檛 just listen passively: Focus and analyze what you鈥檙e hearing. Describe the sound to yourself, draw a diagram, or write it down. If it鈥檚 a complicated song, figure out how many notes it has. Do all the notes have the same tone and vibe? Does the tune rise or fall? Can you adapt the 鈥渟yllables鈥 into words and make a mnemonic? The Barred Owl, for instance, hoots , and the Common Yellowthroat sings . But you don鈥檛 have to just settle for published mnemonics; listen carefully and then invent your own. Little memory hooks like these will make birding easier the next time around. And as always, repetition helps.

Of course, the best place to learn bird voices is outdoors, with the subjects calling right in front of you. Many people find it more effective to listen and watch at the same time, as the visual of the bird reinforces the audio memory. But when you can鈥檛 be out birding, you can take advantage of superb recordings and study aids such as apps, websites, and CDs. 探花精选鈥檚 own online bird guide and free ID app both include hundreds of vocalizations. There are also good books to help you interpret what you鈥檙e hearing, including the new . You can pick a few species at a time鈥攕tarting with birds that are likely in your neighborhood鈥攁nd listen to them on repeat.

For most places in North America, spring and early summer are the peak seasons for birdsong. This is the perfect time to make a late New Year鈥檚 resolution: to improve your birding-by-ear skills. Remember, you don鈥檛 have to learn them all. Getting comfortable with a few species will make your birding more impressive and your forays in nature more exciting and enjoyable.
