I commented recently that during a recent birding trip of rainforest patches
in the Kin Kin area, north of the Sunshine Coast, surprisingly good numbers
of fairy gerygones were recorded, but no brown gerygones, which is the
predominant gerygone in southeast Queensland rainforests.
Yesterday, during a visit to the rainforest in Noosa National Park on the
Sunshine Coast, I again found good numbers of fairy gerygones, and no brown
gerygones. I checked my notes and this is the reversal of the situation
during visits to the park in the 1970s, when only brown gerygones were
recorded.
It seems this is another case of an essentially tropical species spreading
its range southward.
