This is supported by the observation that the nest does not shield the chicks or eggs from rain, and rainfall can sometimes result in clutches being abandoned. Furthermore, it is supported by Immelmann's finding that zebra finches left Wyndham after the first heavy rains in November 1959, but returned to breed in April.
