If they encounter a perched owl, though, they’ll holler chick-a-dee ! with an increasing number of dees depending on the severity of the threat.īirds make contact calls to keep in touch with each other, often while they’re foraging for food. Chickadees, for instance, utter a high seet when they see an aerial predator. But if a raptor is perched, smaller species might try to project deeply and loudly to rally the troops and mob the intruder. This alerts nearby birds without revealing the caller’s location. If a raptor’s flying overhead, a songbird may make a short, quiet, high-pitched sound that won’t carry far. Some calls can even have multiple meanings.Īmazingly, birds can tailor their calls to respond to a wide range of threats. Common Ravens, for example, generate up to 33 different categories of sounds. Songs may be easier on the ears, but tuning in on calls will reveal a staggering amount of variety and complexity among birds. Listen to the standard chip note of the Yellow Warbler: It always sounds pretty much the same, but the songs of the males are endlessly unique. This is important because it leads to more individual variability in songs than in calls. But in many species, the young male must hear its species’ song at a certain age to learn it. Studies have shown that in most songbirds, the basic call notes are instinctive. The Henslow’s Sparrow, for instance, barely sings more than a syllable. Both sexes vocalize with calls, and they can be heard in all seasons.īut be aware that not all songs are so showy. Here’s the Song Sparrow’s chimp call for comparison. One classic example is the the melody of a Song Sparrow.Ĭalls, on the other hand, tend to be shorter and simpler-often just one syllable long. So how can you tell a song from a call? The difference isn’t always obvious, but songs are usually more complex and carry a clear pattern. Therefore, it’s the males that sing the most-usually during breeding season. Among the songbirds and various other groups of birds (such as cuckoos, owls, and nightjars), songs are used to defend territory and attract mates. Most birds have a wide repertoire of songs and call, but there’s an important distinction to be made between the two. Here’s a quick rundown of the kinds of sounds you might hear, and how they're often described by field guides and birders. Or you’ll learn to give a Killdeer some space because it’s “trilling” to protect its nest.

Honing your birding ear can also reveal hidden details in the field. For instance, you’ll know to look for raptors when you hear songbirds whistle in alarm. With a little practice, you can begin decoding all those songs and calls, which will in turn give you remarkable insights into the species around you. It's loud, it's raucous, and for the untrained ear, it's often incoherent. Spring’s here, and there’s a birdy party raging outdoors. To catch up, check out part 1, part 3, part 4, part 5, part 6, part 7, and part 8. In part 2, Bird and Moon creator Rosemary Mosco takes you through the various sounds you hear and what they mean to birds (and to birders).

Follow along with our birding-by-ear series to learn how to better ID birds through their vocalizations. The sheer volume of songs and calls can often feel overwhelming for birders, but these sounds offer both an opportunity and a challenge. Editor’s Note: There's a lot to look forward to in spring, including the welcomed hullabaloo of birdsong.
