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 this list of birds by common name 11,278 extant and recently extinct (since 1500) bird species are recognised. [1] Species marked with a "†" are extinct. Contents
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.
A notable example in birds is the zebra finch. These birds have lateralised brain structures in the face of a common steroid signal, providing strong evidence for a non-hormonal primary sex mechanism regulating brain differentiation.
Finches are a form taxon composed of unrelated but similar-looking songbirds within the family Fringillidae of the superfamily Passeroidea. The family Fringillidae includes numerous birds not called "finches" in their common names, including the crossbills , siskins , and waxbills .
Gauthier and de Queiroz identified four different definitions for the same biological name "Aves", which is a problem. [12] The authors proposed to reserve the term Aves only for the crown group consisting of the last common ancestor of all living birds and all of its descendants, [12] which corresponds to meaning number 4 below. They assigned ...
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.
