    Bird Vocalizations. Birds and mammals have very different vocalization organs. Mammals like us have a larynx (voice box) which is located at the top of the trachea and which manipulates pitch and volume. It houses the vocal folds (also called vocal folds), which are . Vocalization, any sound produced through the action of an animal’s respiratory system and used in communication. Vocal sound, which is virtually limited to frogs, crocodilians and geckos, birds, and mammals, is sometimes the dominant form of communication. In many birds and nonhuman primates the.

Black-Capped Chickadee Chick-a-dee: a variable vocalization with multiple functions, including predator mobbing (in this case, the more dees at the end, the more threatening the predator); as an “all clear” call after the predator has left; or as a food source is located.

The sheer volume of songs and calls to learn can often feel overwhelming for birders, but these sounds offer both an opportunity and a challenge.

Studies of learning mechanisms critically depend on the ability to accurately assess learning outcomes. This assessment can be impeded by the often complex, multidimensional nature of behavior.

We present a novel, automated approach to evaluating imitative learning that is founded in information theory. Conceptually, our approach estimates the amount of information present in a Cited by: 2.

By understanding and recognizing bird sounds rather than relying on visual identification only, you can have a much richer and more enjoyable birding experience, and will be able to identify birds when you can't always see them well.

Proportion of ultrasonic vocalizations emitted by pairs involving a Shank2 +/+ with a C57BL/6N mouse (n = 16, A) and pairs involving a Shank2-/-with a C57BL/6N mouse (n = 13, B) during the following types of behavioral events (red: occupant, green: new-comer): social contacts, oro-oral contact, ano-genital sniffing from the occupant mouse, ano Cited by: Bird vocalizations are produced under various noise conditions.

It could therefore benefit birds to alter the amplitude of their signals as noise conditions change. We tested this by recording male and female zebra finches,Taeniopygia guttata, as they were subjected to various levels of white noise. Both sexes increased amplitude levels of Cited by:
