A clear demonstration of the value of a long memory.
Your post caused me to look at the 1st Atlas of Australian Birds (1977 to
1981) which clearly shows the much wider distribution of the species than is
shown in Birdata or the 2nd Atlas. Presumably this distribution is the
result of the '76-77 and 80-81 irruptions?
Can it also be inferred that there has not been a major irruption since 1981
(ie about 29 years ago)?
