# Songs & Calls

Part of the Bird Study Merit Badge Digital Resource Guide: [Introduction & Overview](https://merit-badge.university/merit-badges/bird-study/guide/index.md)

*7. Bird Songs & Calls*

> **7.** Explain the function of a bird's song. Be able to identify five of the 20 species in your field notebook by song or call alone. Explain the difference between songs and calls. For each of these five species, enter a description of the song or call, and note the behavior of the bird making the sound. Note why you think the bird was making the call or song that you heard.

Birding by ear is one of the most powerful skills you can develop. On a typical morning walk through a forest, you might see a handful of birds — but you can hear dozens. Learning to identify birds by their sounds will dramatically increase the number of species you can detect, and it will deepen your understanding of bird behavior.

## Songs vs. Calls — What Is the Difference?

This is a key distinction for your counselor conversation:

### Songs

**Songs** are typically long, complex, and musical. They are produced almost exclusively by **male** songbirds (with some exceptions), primarily during the **breeding season**. Songs serve two main functions:

1. **Attracting a mate** — A male's song advertises his fitness and territory to females.
2. **Defending territory** — A song warns other males: "This area is taken. Stay away."

Songs are usually learned — young birds hear their father's song and practice it until they get it right. Some species, like the Northern Mockingbird, learn and reproduce the songs of many other species.

### Calls

**Calls** are short, simple sounds made by both males and females throughout the year. They serve practical, immediate purposes:

- **Alarm calls** — Warning of a predator ("Hawk! Get down!")
- **Contact calls** — Staying in touch with the flock ("I am here, where are you?")
- **Begging calls** — Nestlings begging parents for food
- **Flight calls** — Coordinating group movement during migration or flock flight

| Feature | Song | Call |
|---|---|---|
| Length | Long, complex | Short, simple |
| Who sings | Mostly males | Both males and females |
| When | Mainly breeding season | Year-round |
| Purpose | Attract mate, defend territory | Alarm, contact, begging |
| Learned? | Usually learned from parents | Mostly innate (born knowing it) |

> The Brown Thrasher holds the record for the largest song repertoire of any North American bird — over 1,100 different song types. Each phrase is typically sung twice before moving on to the next, creating an endlessly varied performance.

## Why Do Birds Sing?

The function of bird song comes down to survival and reproduction:

**Territory defense** — A singing bird is announcing ownership of a patch of habitat that contains food, shelter, and nesting sites. Studies have shown that when a territorial male is removed, neighboring males quickly expand into his area — but when a speaker playing his song is placed in the territory, the neighbors stay away. The song alone is enough to defend the territory.

**Mate attraction** — Females often choose mates based on the quality and complexity of their songs. A male with a bigger song repertoire may signal better genes, better health, or more experience — all desirable traits in a partner.

**Species recognition** — Each species has a unique song pattern. This helps birds find mates of their own species, even in habitats shared with many other species.

## Learning to Identify Birds by Sound

For this requirement, you need to identify **five** of the 20 species in your field notebook by song or call alone. Here is how to build that skill:

### Start with Common, Distinctive Songs

Some birds have songs that are easy to remember because they sound like English phrases. These **mnemonics** (memory aids) have been used by birders for generations:

| Bird | Mnemonic | Sound Description |
|---|---|---|
| Barred Owl | "Who cooks for you? Who cooks for you-all?" | Deep, hooting rhythm |
| White-throated Sparrow | "Oh sweet Canada, Canada, Canada" | Clear, whistled notes |
| Carolina Wren | "Teakettle, teakettle, teakettle" | Loud, rolling phrase |
| American Robin | "Cheerily, cheer up, cheer up, cheerily" | Rich, caroling melody |
| Black-capped Chickadee | "Chick-a-dee-dee-dee" (call) | Buzzy, staccato notes |

### Use Technology

- **Merlin Bird ID** (free app) — Has a "Sound ID" feature that listens through your phone's microphone and identifies birds singing in real time. Use it to confirm what you hear.
- **Cornell Lab's Macaulay Library** — The world's largest archive of bird sounds. You can listen to recordings of any North American species online.
- **eBird** — Species pages include sound recordings alongside photos and range maps.

> **Tip**
>
> Practice in short sessions. Listen to a bird's song three or four times on a recording, then go outside and try to find that bird by ear. Connecting the recorded sound to a real bird in the field makes it stick in your memory far better than listening at your computer alone.

## Recording Your Five Species

For each of the five species you identify by sound, your field notebook entry should include:

1. **A description of the song or call** — Use words like buzzy, whistled, trilled, warbled, harsh, musical, ascending, descending. Try to capture the rhythm and pattern.
2. **The behavior of the bird** — What was the bird doing while singing? Perched on a high branch? Hidden in a thicket? Flying overhead?
3. **Why you think it was making that sound** — Was it defending territory (singing from an exposed perch)? Alarming about a predator (short, rapid call notes)? Calling to a mate or flock?

> **Be Prepared! Describing Songs in Writing**
>
> Writing down what a bird sounds like is tricky. Here are some useful descriptive words:
>
> - **Pitch:** high, low, rising, falling, steady
> - **Tone:** clear, buzzy, raspy, nasal, musical, harsh, mellow
> - **Pattern:** repeated phrases, alternating notes, trill (rapid series), warble (complex and varied)
> - **Rhythm:** fast, slow, accelerating, decelerating, evenly spaced
> - **Volume:** loud, soft, carrying (heard from far away)
>
> Example: "The Carolina Wren's song is a loud, clear, rapidly repeated phrase of three syllables — 'teakettle teakettle teakettle.' The bird was perched on a low branch at the edge of a thicket, singing persistently. I believe it was defending its territory because it sang from the same spot for several minutes and chased another wren that approached."
