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]
The main focus of Zann's ornithological research was the zebra finch. [2] This work was synthesised in the 1996 book Zebra Finch: A Synthesis of Field and Laboratory Studies, which has been described as his magnum opus. [2] Zann was also known for his studies on the island biogeography of the volcanic island of Krakatau, Indonesia.

The true finches are small to medium-sized passerine birds in the family Fringillidae. Finches generally have stout conical bills adapted for eating seeds and nuts and often have colourful plumage. They occupy a great range of habitats where they are usually resident and do not migrate. They have a worldwide native distribution except for ...
Inbreeding causes early death (inbreeding depression) in the zebra finch Taeniopygia guttata. [259] Embryo survival (that is, hatching success of fertile eggs) was significantly lower for sib-sib mating pairs than for unrelated pairs. [260]
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.
