Abstract
The zebra finch is widely distributed in Australia,
inhabiting the central arid regions as well as the
semiarid and coastal areas. This extensive distribution
suggests the possibility that 'physiological
races' exist, which use different kinds of
environmental information to control reproduction.
1 In the zebra finch of the arid regions
(Taeniopygia guttata castanotis), as in many other
species of these areas, breeding activity is not
photoperiodically induced, but follows the onset
of rainfall. 2 However, it is not clear whether the
critical environmental stimuli inducing the onset
of breeding are primarily the increased air humidity,
the greater availability of drinking water, or
the nutritionally important lush growth of vegetation
that follows the onset of rainfall. Endogenous
periodicity does not appear to be an important
determinant of the onset of breeding since
rainfall-dependent breeding activity in the arid
areas may occur at any time of the year. 3
