Some birds will respond to a shared song type with a song-type match (i.e. with the same song type). [24] This may be an aggressive signal; however, results are mixed. [23] Birds may also interact using repertoire-matches, wherein a bird responds with a song type that is in its rival's repertoire but is not the song that it is currently singing ...
Birds regulate the airflow through the syrinx with muscles—M. syringealis dorsalis and M. tracheobronchialis dorsalis—that control the medial and lateral labia in the syrinx, whose action may close off airflow. [2] Song may, hence, be produced unilaterally through one side of the syrinx when the labia are closed in the opposite side.
HVC is located in the caudal nidopallium.It projects to the song motor pathway via the robust nucleus of the arcopallium (RA) and to the Anterior Forebrain Pathway via the basal ganglia nucleus Area X. [1] It receives recurrent motor activity through the thalamic nucleus Uvaformis (Uva) and input from the auditory system through projections from the caudalateral mesopallium (CMM) and through ...
Amphibian vocalization; Bird vocalization, bird calls and bird songs; Dolphin vocalizations; Female copulatory vocalizations, produced by females while mating; Voice (phonetics), the vibration of the vocal cords that accompanies some speech sounds Consonant voicing and devoicing, the addition or removal of this vibration from consonant sounds
The syrinx (from the Greek word "σύριγξ" for pan pipes) is the vocal organ of birds. Located at the base of a bird's trachea , it produces sounds without the vocal folds of mammals. [ 1 ] The sound is produced by vibrations of some or all of the membrana tympaniformis (the walls of the syrinx) and the pessulus , caused by air flowing ...
The Secret Language of Birds is the third studio album by Jethro Tull frontman Ian Anderson, released in 2000. [1] It is named after the dawn chorus , the natural sound of birds heard at dawn, most noticeably in the spring.
The common nighthawk or bullbat (Chordeiles minor) is a medium-sized [3] [4] crepuscular or nocturnal bird [3] [5] of the Americas within the nightjar (Caprimulgidae) family, whose presence and identity are best revealed by its vocalization. Typically dark [3] (gray, black and brown), [5] displaying cryptic colouration and intricate patterns ...
[2] [3] Body mass ranges from 11.9 to 53 g (0.42 to 1.87 oz). [4] The average of all races is 32 g (1.1 oz) but the widespread nominate subspecies (M. m. melodia) weighs only about 22 g (0.78 oz) on average. The maximum lifespan in the wild is 11.3 years. [5] The eggs of the song sparrow are brown with greenish-white spots.
