They don’t all sing like Beyoncé or Ella Fitzgerald.Ĭommon Ravens, for example, are actually big, fat songbirds. These birds belt out many of the world’s most impressive songs.īut not all songbirds sing so nicely. Suffice it to say there are many bird families that belong to the oscine passerine group. These are the wrens, thrushes, finches, starlings, warblers, larks, chickadees… and there’s no way I’m going to list them all here. So, in the evolutionary sense, this is a wildly successful group. Oscine comes from the Latin word oscen, which translated one way means, “bird which gives omens by its cry.”īesides being great at giving omens, the oscine passerines have some of the world’s most amazing vocal abilities.Ībout half of the planet’s bird species, about 5,000 of them, are songbirds. This is a subset of the order passeriformes-otherwise known as the perching birds. In ornithology, songbird is the common word we use for members of a particular evolutionary lineage known as the oscine passerines. Isn’t any bird that sings a song bird? Well, in the poetic sense, yes. What exactly is a “songbird?” I used that word above, and it’s a common one that we all know. The bird is only about 12 inches (31 centimeters) long, but it’s trachea is 30 inches (75 centimeters) long. This member of the Bird of Paradise family has a super long trachea, which is coiled up like a garden hose just under the skin of its chest. The shape and size of a bird’s bill also can change the sound, as can the way a bird moves its bill while it sings.Īs for the trachea, some types of birds-including swans and cranes-have long ones that increase the resonance of their voices.įor example, the Trumpet Manucode from the island of New Guinea. This is kind of like being able to sing a two-part harmony of “Bohemian Rhapsody” with yourself.Īs a bird’s voice moves from the syrinx and out into the world for all to hear, it can be modified by things like the length and diameter of the trachea. These birds can control the two sides of their syrinx independently. Of these, the syrinx of songbirds is arguably the most sophisticated.Īnother key difference between the voices of birds and mammals like us is that many birds can produce two independent vocal sounds simultaneously with their syrinx. There are a few distinct, anatomical forms of the syrinx, found in different bird groups. Muscles in the syrinx contract and relax to manipulate the sound-the bird’s voice-to change its pitch and amplitude. Thin membranes in the syrinx vibrate as exhaled air rushes past them. This is where the airway, the single tube of the trachea, forks into two tubes, called bronchi, which connect to the lungs. Instead, they have an anatomical structure unique to birds called a syrinx.Ĭompared to the human larynx, the syrinx of a bird is located further down in the respiratory pathway, closer to the lungs. They have a larynx, but it doesn’t serve that function. But there are a couple big differences.įor starters, birds don’t make sound with their larynx. What comes out is the melodious noise of the human voice.īird voices are produced in a similar way. Further modifications of the sound result from movements of the tongue and lips. Pitch and volume are changed by movements of muscles around the larynx. Air pushed out from the lungs vibrates the vocal cords in the larynx, and this makes a sound. Humans make sound waves with the larynx, our so-called voice box. In this article, we’re going to focus just on the vocal sounds of birds and leave those other sounds for another time. This low-frequency sound travels easily through dense forest vegetation.Īnd you’re probably familiar with the actual drumming sounds made by woodpeckers. For example, the Common Snipe makes a winnowing sound with its tail feathers as it makes an aerial display dive.Ī male Ruffed Grouse beats its wings rapidly to make a low-frequency, drum-like sound while perched on his favorite log in the forest. Some species make sounds with their feathers. Humans, too, are a noisy bunch, so it’s not surprising that we’re interested in these creatures that also use sound extensively.īirds make sound in a variety of ways, not just with their voices. We’re delighted and fascinated by the voices of birds. Besides having feathers and the ability to fly, singing is one thing that really stands out about birds. Compared to most mammals and other animals that we encounter daily, birds make a lot of racket. If we slow down occasionally and use our ears to survey which birds are singing nearby, we can often be surprised by the diversity of species and of bird sounds that are all around us.īirds are noisy. Even when we can’t see them, we can usually hear them. Birds are never very far from us, no matter where we are on Earth.
