The zebra finch genome was the second bird genome to be sequenced, in 2008, after that of the chicken. [32] The Australian zebra finch uses an acoustic signal to communicate to embryos. It gives an incubation call to its eggs when the weather is hot—above 26 °C (79 °F)—and when the end of their incubation period is near.
The Australian zebra finch is used worldwide in several research fields (e.g. neurobiology, physiology, behaviour, ecology and evolution) as individuals are easy to maintain and breed in captivity. [12] Zebra finches are more social than many migratory birds, generally traveling in small bands and sometimes gathering in larger groups. [13]
In 2001, Woolley began a second postdoctoral fellowship at the University of California, Berkeley, where she studied the way zebra finches were able to distinguish vocalizations of specific individuals and also differentiate vocalizations from other sounds. [9] She found that the finch's auditory neurons were better able to more accurately ...
A recent study has shown that a dopamine circuit in zebra finches may promote social learning of bird song from tutors. [115] Their data shows that certain brain areas in juvenile zebra finches are excited by the singing of conspecific (i.e. same-species) tutors and not by loudspeakers playing zebra finch song.
Zebra Finch (Taeniopygia guttata) at the Essehof Zoo in Germany. Only male zebra finches sing. [4] Each finch has an individual song. [4] Between the ages of 25 and 90 days old, young zebra finches learn to sing by copying the songs of adults, and sometimes by copying the songs of other juveniles.
Certain words in the English language represent animal sounds: the noises and vocalizations of particular animals, especially noises used by animals for communication. The words can be used as verbs or interjections in addition to nouns , and many of them are also specifically onomatopoeic .
In male zebra finches, neurons in Field L and CM do not exhibit a preference for different types of conspecific songs (in contrast to neurons in NCM, and those that participate in the AFP and SMP). Field L and CM neurons do not discriminate between the tutor song, the bird's own song, or individual conspecifics. [27]
The example STRF here is for an auditory neuron from the area CM (caudal medial) of a male zebra finch, when played conspecific birdsong. The colour of this plot shows the effect of sound on this neuron: this neuron tends to be excited by sound from about 2.5 kHz to 7 kHz heard by the animal 12 ms ago, but it is inhibited by sound in the same frequency range from about 18 ms ago.
