Table 1.
Waterhole locations and sampling frequencies.
Fig 1.
Frequency of age and sex classes and head colour morphs in Gouldian finches descending first to the ground.
(A) Observed values (black) are plotted beside the expected value (grey) for each class for black-headed (BH) males and females, red-headed (RH) males and females and uniform juveniles; (B) observed and expected frequencies for adults and juveniles only (pooled across sexes and head colour morphs).
Fig 2.
Frequencies of sex classes landing first on the ground early and late in the season.
Observed (black) and expected (grey) frequencies of males and females being first on the ground early (A) and late (B) in the season.
Fig 3.
Frequency of first species on ground at waterholes.
(A) Frequencies for Gouldian finches, Long-tailed finches and ‘other’ species (see text) descending first to the ground tested against an equal expectation of 1/3 for each group (black line); (B) Observed (black) and expected (grey) frequencies of Gouldian finches following another Gouldian finch, a Long-tailed finch or an ‘other’ species to the ground.
