How to Learn Birdsong

 

In the appreciation of birds I should sooner sacrifice eyesight than hearing.

This site now hosts several compilations of local bird sounds:

  1. Ten Backyard Birdsongs
  2. Ten Woodland Birdsongs
  3. Ten Backyard Calls
  4. Ten Woodland Calls
  5. Ten Fall Bird Sounds

You certainly could dive right into the recordings, but even with the bird list pared down to the essential species, you might still find it a little overwhelming and difficult. How do you remember each song and keep them straight in your memory? In this post, I’m going to give you the tips, techniques, and resources to make learning our local bird sounds as easy as possible.

First, let’s set the scene and establish some basics.

What is birdsong?  

Male birds, like this house finch, do most of the singing – Risa George

Birdsong is the music of the nesting season. Throughout the year, birds make sounds and vocalizations of various kinds: most of these are lumped together under the catch-all term of calls. Calls can have various functions – staying in touch, sounding the alarm, signalling aggression – but most are characterized by their brevity and relative simplicity. We humans describe songs as songs, however, because they often are songlike to our ears, with relatively more length, complexity, and musical quality.

How exactly does song relate to the nesting season? It is mostly male birds that sing, and they do so for a few reasons. The first and largest is to signal their health and fitness to potential mates. Singing takes energy and a more energetic performance directly shows health and vigor. Singing also takes time and makes one more obvious to predators: a bird that was barely getting by would keep a lower profile and focus on finding enough food for himself rather than spending precious hours of the day in song. A bird that sings must therefore be doing well, with a demonstrated lifestyle cushion above mere bachelor subsistence.

The second function of song is to signal health, fitness, and breeding readiness not just to females, but to rival males as well. Most songbirds maintain a territory during the nesting season, a defined area from which they aim to exclude other birds, especially males of their own species. This may include guarding some food sources, but the main goal is to guard the nest and female, with the clear evolutionary purpose of ensuring that those eggs she’s sitting on are his eggs. By singing, often near the boundaries of the territory, the male bird warns would-be interlopers that he is a strong and vigorous opponent who intends to defend the area. In many cases, this verbal and visual warning is enough to avoid the need for actual physical combat.

So we have a decent idea what the evolutionary functions of birdsong are. We can still congratulate ourselves that this functional process from the ruthless economy of nature takes a form so pleasant to our ears. In a sense, it’s ultimately not that surprising, since we’re all part of the same world, birds and humans evolving side by side across the ages. But when we are accustomed to living within our bounded human sphere, it is easy to forget this commonality. Easy to forget, but fortunately easy to remember, easy to step outside on a fine spring morning and be suddenly struck by our profound good luck to live in a world where some force has seen fit to

     … fling
Rainbows over the rain
And beauty above the moon, and secret rainbows
On the domes of deep sea-shells,
And make the necessary embrace of breeding
Beautiful also as fire,
Not even the weeds to multiply without blossom
Nor the birds without music.

– Robinson Jeffers, “The Excesses of God”

How do you learn it?

One handy side effect of the relative complexity of songs compared to calls is that it makes it easier for us auditorily imprecise humans to tell the different birds apart. Easier, but not necessarily automatic: most people aren’t naturally skilled or practiced at remembering abstract sounds. If you apply the right techniques, however, if you approach birdsong with the patterns of thinking that your brain is trained to use, you will meet with unexpected success and find new vistas of sound and awareness opening up before you with really a very modest effort.

The key to converting birdsong to a more amenable human learning process is to use words. (At least on the introductory level: the real bird nerds who need to distinguish very similar calls eventually dive into the fascinating world of sonograms.) Most of us humans do not naturally deal well with remembering abstract sounds. Or images really. One of the most common mistakes of beginning birdwatchers is to see a bird, then rush to flip through the book to look for a matching picture, then to be confused when confronted with a few similar-looking possibilities. The key is to note as many specific features as possible, in words: Black head, reddish sides, white belly. A black tail, but white outer tail feathers. And so on.

Have you ever made that mistake when trying to identify a new bird you’ve seen? Stop doing that. And don’t do it with songs, hearing a new sound and then trying to identify it based on a cloudy general impression or a single adjective of loose description. We need more precision.

USE WORDS

In the case of sounds, we have three different ways of converting songs into material our language-trained brains can handle and remember. These three tools are mnemonics, transliteration, and description. Let me give you an example of each with an easy and distinctive song, that of the golden-crowned sparrow. This is a very common winter bird here, which arrives in late September or early October and sings this song when most of our residents have grown quiet.

(To replay the main song at the beginning, click the stop button, then the play button)

Mnemonics: These memory devices work by combining an appropriate meaning from human language with a general imitation of the sound in question. The golden-crown song has three syllables and sound rather tired and wistful, so one common mnemonic is “I’m so tired.” Other options include “Oh dear me” and “no gold here” (the last popular with despondent Yukon gold miners).

Transliteration: Unlike mnemonics, transliterations don’t attempt use actual English words. Instead they use our alphabet to imitate the sounds as closely as possible. For the gold-crown, you might get something like “seeea seeeew soooo.” Here, the three words capture the three notes of the song, the “s”s capture the slurred and whistled quality, the repeated vowels imitated the long and drawn-out notes, and the switch from “e” sounds to the final “oo” sound mirrors the drop in pitch.

Description: This classically musical song might be described as “three clear, long, high whistles, slurring together and descending in pitch.” Some songs can be easily described like this in their tempo (fast or slow), pitch (high, low, descending, ascending), tone (whistled, buzzy, raspy, muffled), and other musical qualities, while others might be best described by everyday adjectives or analogy (the California towhee call sounds to some like a “low battery alert on a smoke detector).

Listen to that golden-crowned sparrow song a few times, thinking of whichever one of those wordification techniques feels most natural to you. Take this approach with any birdsong you want to remember: read mnemonics, transliterations, or descriptions on websites or in field guides and think of them while listening to the sound. Find something that works in your mind, that feels both accurately and precisely descriptive of that particular sound to your ears.

The Morse Code Technique

When dealing with long and complex songs, I have one other technique that often seems to help beginners. I call it the “Morse code” technique, inspired by a related anecdote in Donald Kroodsma’s book The Singing Life of Birds. Apparently, when radio operators are learning Morse code, they are encouraged not to attempt to slow down communications and pick out every single letter, but instead to listen to recordings at full speed and focus on picking out just a few letters. You can apply this to complex bird songs by focusing on a specific and distinctive element within the song, such as the staccato ending notes at the end of the Bewick’s Wren song or the “po-ta-to-chip” calls that American goldfinches are always making.

For example, listen first to this simple Bewick’s wren song and then a more complex version. You might be confused by the extra material in the second song, but listen for that distinctive tag of repeated, staccato notes at the end: if you recognize that bit, you will know who is singing.

Tools for Practice

So, I recommend a basic practice routine of 1) listening to songs, while 2) thinking of words. Where do you get the songs and the words?

One-Stop Shop for the Essential Birds: If you don’t know where to start and you live here in the San Francisco Bay Area or Northern California, I would look at our two beginner collections of the Top 10 Backyard Birdsongs and the Top 10 Woodland Birdsongs, including both recordings representative of the sounds the local birds make and my descriptions.

Merlin Bird ID is the best free app, with sounds and sonograms, although inexplicably no verbal song descriptions.

Song Recordings: As you move beyond the basics, it has fortunately never been easier to find high quality recordings. A good first stop is usually the Cornell Lab of Ornithology’s All About Birds website, which has a curated selection of recordings with good descriptions and even sonograms (if you click the link to the Macauley Library source file). Any bird identification app for smartphone or tablet will also include recordings: try out Cornell’s free Merlin app, iBird, or the app version of your favorite field guide (Sibley, National Geographic, Peterson, etc.)

Descriptions: All About Birds and many of the apps also include some form of description along with the recordings: read them carefully and think about them seriously – they are as important as the sounds. If you don’t like their descriptions, pull out your normal printed field guide and see what that author has to say. And if you want to become a real expert, you can graduate to the more systematic transliterations and sonograms featured in the Peterson Field Guide to Bird Sounds, a magisterial book with companion website. And you can always make up your own!
