Bird Song vs Call, and Why the Difference Matters

What is the difference between a bird song and a call, and what are alarm calls? Learn how to tell them apart and why it makes birds easier to identify.

When people start learning birds by ear, they often lump every sound together as "birdsong." But birds make several different kinds of sounds, for different reasons, at different times of year. Knowing which kind you are hearing is one of the quickest ways to narrow down who is making it.

This post covers the three main categories beginners run into: songs, calls, and alarm calls. It also touches on a few sounds birds make without using their voice at all.

What is a bird song?

A song is usually the longer, more elaborate, more patterned sound a bird makes. It is what most people picture when they think of birds singing.

In many North American songbirds, songs have a few things in common:

They are mostly about territory and mates. Songs help a bird claim an area and attract or keep a partner.
They are seasonal. Song is usually strongest in spring and early summer, during the breeding season. Many birds sing much less, or not at all, in late summer, fall, and winter.
They are often sung by males. In many North American species, males do most of the singing. But not always. Female Northern Cardinals, for example, sing too, and in some species both partners sing.
They are often learned. Songbirds generally learn their songs by listening to adults when they are young. That is one reason songs can vary from place to place, a bit like regional accents.

Songs are often heard most in the early morning, though many birds sing at other times of day as well.

What is a bird call?

A call is usually short and simple. A single chip, tseet, tut, or caw is typically a call.

Calls tend to differ from songs in a few ways:

They are used year-round. You can hear calls in every season, which matters a lot in fall and winter, when there is little song.
Both sexes use them. Calls are not usually limited to males or to the breeding season.
They have many everyday jobs. Birds use calls to keep in touch with a mate or flock, to signal that they are about to fly, to beg for food as youngsters, and to communicate during migration.

Many birds have several different calls. The American Robin, for example, has a rich caroling song in spring, but also gives short tut or pup calls, and other calls, throughout the year.

The line between songs and calls is not always sharp. Some birds have sounds that do not fit neatly into either box, and you may see field guides describe the same sound differently. That is fine. The categories are a tool, not a strict rule.

What is an alarm call?

An alarm call is a kind of call given when a bird senses danger, such as a hawk, a cat, a snake, or a person getting too close.

Alarm calls often sound sharp, harsh, urgent, or insistent. Many birds have more than one kind:

Mobbing or scolding calls. These are often harsh, repeated, and loud. They are used when a predator is perched or on the ground, and they can draw other birds in to harass it. The scolding chick-a-dee-dee-dee of a Black-capped Chickadee is a familiar example, and other small birds often respond to it.
High, thin warning notes. Many small birds give a very high, thin seet when a hawk flies overhead. These calls are often hard to locate, which may help the caller avoid drawing attention to itself.

For birders, alarm calls are worth noticing even when you cannot identify every voice. A sudden burst of scolding from several species often means an owl, hawk, or cat is nearby.

Sounds that are not songs or calls

Some birds make distinctive sounds without using their voice:

Woodpecker drumming. Woodpeckers drum rapidly on wood, metal, or other surfaces to communicate, much as other birds use song.
Wing sounds. The Mourning Dove's wings often make a whistling sound when it takes off.
Display sounds. The Wilson's Snipe makes an eerie, pulsing "winnowing" sound during display flights, produced by air rushing over its outer tail feathers.

These are worth learning too, but it helps to know they are a different kind of sound so you do not go looking for them among song recordings.

Why the distinction helps identification

Sorting a sound into song, call, or alarm before trying to name the bird has a few practical benefits.

It narrows the possibilities

If you hear a short chip in winter, you can rule out comparing it to song recordings. If you hear a long, varied song in May, you can focus on birds that sing at that time of year. Each decision cuts down the list.

It matches the season

Because song is concentrated in the breeding season, what you hear changes through the year. In spring, the air is full of songs. In fall and winter, most of what you hear is calls. Many beginners learn a few songs in spring, then feel lost in October. Knowing that you need to learn calls too makes that less of a surprise.

It helps you use recordings well

Most recording archives label sounds by type. If you know you are listening to a call, you can go straight to the call recordings instead of scrolling through songs.

It tells you what is happening

A bird singing from a high perch is usually advertising its territory. A bird giving a harsh, repeated call is often upset about something. Paying attention to the type of sound gives you a little window into what the bird is doing, which makes listening more interesting and the sound easier to remember.

A simple habit to build

Next time you hear a bird, before you try to name it, ask yourself one question: song, call, or alarm?

Long and patterned? Probably a song.
Short and simple? Probably a call.
Harsh, urgent, or repeated with other birds joining in? Possibly an alarm.

You will not always be sure, and that is normal. The habit of asking is what matters. Over time it becomes automatic, and it makes every other identification step easier.

Where BirdBrain can help

The free Bird sound basics course includes a short lesson called "Song, call, or alarm?" that covers this distinction with examples. It takes no signup. If you want to hear songs and calls for specific birds, each page in the free bird sounds library includes recordings and notes on what to listen for.
