Why do birds have voices? The melodious call of many birds comes from a mysterious organ buried deep within their chests: a one-of-a-kind voice box called a syrinx. Folds of tissue there—the vocal cords—can also vibrate to enable humans to talk, pigs to grunt, and lions to roar.
Why do birds sing?
Bird song is an integral part of bird courtship and is a pre-zygotic isolation mechanism involved in the process of speciation. Many allopatric sub-species show differences in calls. These differences are sometimes minute, often detectable only in the sonograms.
How does a bird make sound?
The syrinx and sometimes a surrounding air sac resonate to sound waves that are made by membranes past which the bird forces air. The bird controls the pitch by changing the tension on the membranes and controls both pitch and volume by changing the force of exhalation.
How do birds communicate in flight?
All birds have a separate type of communication for "songs" vs. communicating danger and other information. Konrad Lorenz demonstrated that Jackdaws have "names" identifying each individual in the flock and when beginning flight preparations each of them say one other bird's name creating a "chain".
Why do I hear bird calls all year?
You can hear these calls at any time of year because birds have to keep track of each other in all seasons. Sometimes these sounds are referred to as feeding calls or contact calls on bird vocalization CDs.
Why are birds so vocal?
Birds use songs for a variety of purposes, depending on the season and each individual bird's needs. The most common reasons for birds to sing include: Claiming and defending territory: A loud, complex song advertises to nearby birds that the territory is already inhabited by a healthy, active male.
Why do birds make that noise?
Birds make contact calls to keep in touch with each other, often while they're foraging for food. These sounds are usually short, quick, and quiet, though if birds get separated, they may make louder, more urgent “separation calls.”
Do birds have voices?
Unlike humans, birds produce vocal sounds using a syrinxSEE-rinksthe bird voice box, located at the branch point between the trachea and bronchi and containing vibrating tissues called labia, in songbirds capable of making two sounds at once via independent muscle control, an organ located where the trachea splits into ...
Why do birds sing when they hear music?
He said he was aware of a good study from 2012 that suggested that bird brains respond to song in the same areas that human brains do. “As a shorthand way of thinking, if a bird song sounds musical to human ears, odds are that similar human music will sound songlike to the bird,” Dr. DeVoogd said.
What do birds talk about?
Birds communicate with vocal sounds like songs, companion calls & alarm calls as well as with visual cues like body language & behavior. These messages are used by birds to find mates, keep track of friends & family, to locate food, stay safe from predators, and defend territories from rival birds.

Why do birds sing answer?
While birds might be happy, they sing in order to communicate. One reason they sing is to stake a claim on territory. Birds sing to warn other birds to stay off their property. For example, a robin might stake a claim on a piece of land which measures about 200 feet wide by 200 feet long.
How do birds learn to sing?
Birds learn to sing in much the same way humans learn to talk: by listening to, and then imitating, the vocal sounds of their elders. Of course, those sounds rarely come out right the first time, but a fledgling's sense of hearing can tell her just how off the mark she is.
Do birds enjoy human music?
Birds whistle and "sing" as a form of communication. Why do they sing along to music? It's hard to say for sure, but many experts suggest that birds are highly social creatures who enjoy music similarly to people and are moved to dance and "sing along" the same way we are.
Do birds sleep?
Unless they are in a state of torpor, birds tend to sleep in small snatches until startled awake either by a predatory threat, neighbor, or cold conditions. Some can even sleep with one eye open, as half of their brain is alert while the other is asleep.
Do birds pee?
The answer lies in the fact that birds, unlike mammals, don't produce urine. Instead they excrete nitrogenous wastes in the form of uric acid, which emerges as a white paste.

How do songbirds learn?
Songbirds listen, learn, and practice a lot like we do. As nestlings they tune in to neighborhood songs by listening closely and committing them to memory. It is only later, after they’ve fledged, that young birds begin to practice. The early practice songs are messy and unstructured, a lot like the babbling#N#in humans, to practice talking by stringing together sounds, as babies do before they can produce clear words or sentences, analogous to plastic song in songbirds#N#of a young child. After many months of practice, songbirds refine their songs and settle on a repertoire, which often stays fixed for the rest of their lives.

Overview
Function
One of the two main functions of bird song is mate attraction. Scientists hypothesize that bird song evolved through sexual selection, and experiments suggest that the quality of bird song may be a good indicator of fitness. Experiments also suggest that parasites and diseases may directly affect song characteristics such as song rate, which thereby act as reliable indicators of h…
Definition
The distinction between songs and calls is based upon complexity, length, and context. Songs are longer and more complex and are associated with territory and courtship and mating, while calls tend to serve such functions as alarms or keeping members of a flock in contact. Other authorities such as Howell and Webb (1995) make the distinction based on function, so that short vocalizatio…
Anatomy and physiology
The avian vocal organ is called the syrinx; it is a bony structure at the bottom of the trachea (unlike the larynx at the top of the mammalian trachea). The syrinx and sometimes a surrounding air sac resonate to sound waves that are made by membranes past which the bird forces air. The bird controls the pitch by changing the tension on the membranes and controls both pitch and volume by changing the force of exhalation. It can control the two sides of the trachea independently, w…
Neuroanatomy
The acquisition and learning of bird song involves a group of distinct brain areas that are aligned in two connecting pathways:
• Anterior forebrain pathway (vocal learning): composed of Area X, which is a homologue to mammalian basal ganglia; the lateral part of the magnocellular nucleus of anterior nidopallium (LMAN), also considered a part of the avian ba…
Learning
The songs of different species of birds vary and are generally typical of the species. Species vary greatly in the complexity of their songs and in the number of distinct kinds of song they sing (up to 3000 in the brown thrasher); individuals within some species vary in the same way. In a few species, such as lyrebirds and mockingbirds, songs imbed arbitrary elements learned in the individual's lif…
Identification and systematics
The specificity of bird calls has been used extensively for species identification. The calls of birds have been described using words or nonsense syllables or line diagrams. Common terms in English include words such as quack, chirp and chirrup. These are subject to imagination and vary greatly; a well-known example is the white-throated sparrow's song, given in Canada as O sweet Cana…
Bird language
The language of the birds has long been a topic for anecdote and speculation. That calls have meanings that are interpreted by their listeners has been well demonstrated. Domestic chickens have distinctive alarm calls for aerial and ground predators, and they respond to these alarm calls appropriately.
However, a language has, in addition to words, grammar (that is, structures and rules). Studies to …
