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]
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.
In the 1980s her research program expanded to include research in both Japanese quail and zebra finches. In the socially-monogamous zebra finches, she performed a series of parallel experiments demonstrating the effects of steroid hormones on the development sexually differentiated behaviors in these songbirds.

Female birds are able to produce more of a certain gender of birds that are more likely to survive under extreme conditions. In birds, the females' egg determines the gender of the offspring, not the male's sperm. In zebra finches, a study showed the effect of food on gender ratio production. For females, egg production is a metabolically ...
[2] [22] When male and female European starlings are trained to recognize conspecific song, there is an associated change in the response of CMM neurons, [28] and female zebra finches experience a reduced ability to discriminate between conspecific and heterospecific song following lesions to the region. [29]
Hattiesburg Zoo on Sunday welcomed a new member to its family with the birth of a female zebra. The female foal was born to 3-year-old Samira and 7-year old Bakari. It was Samira's first foal, zoo ...
Alternatively, the distribution of male and female tissue can be more haphazard. Bilateral gynandromorphy arises very early in development, typically when the organism has between 8 and 64 cells. [25] Later stages produce a more random pattern. [citation needed] A notable example in birds is the zebra finch.
Sporophila is a genus of Neotropical birds in the tanager family Thraupidae. The genus now includes the six seed finches that were previously placed in the genus Oryzoborus. They are relatively small with stubby, conical bills adapted for feeding on seeds and alike.
