This is the fourth post demonstrating changes in the status and distribution of birds in South-East Queensland over 40 years between 1979 - when my booklet The Birds of South-East Queensland was published – and 2019. The list covers only those species where a significant change has been noted over the intervening period. Some changes are doubtlessly influenced by an increased number of observers and technological advances (especially with playback) but many can not be explained by these factors. See here for Part 1 (emu to storm-petrels) and here for Part 2 (boobies to hawks); Part 3 (brush-turkey to terns) is here.
|Red-tailed Black Cockatoo|
Double-eyed (Coxen's) Fig-Parrot. In 1979 it was described as “possibly extinct” with recent reports unconfirmed. That could be downgraded to “probably extinct” today with recent records still unconfirmed. Many reports of sightings are accepted as valid by Queensland Government authorities that should know better. As I have reported elsewhere, not a single one of these records has been corroborated by follow-up sightings, a photograph, specimen or sound-recording. It is remotely possible (but unlikely in my view) that it survives in very small numbers.
|Eastern Ground Parrot|
Paradise Parrot. Described as “possibly extinct” in 1979, it can safely and regrettably today be deemed extinct. I reported back then that the last published observation was in 1927 in the upper Burnett. I've since reported that the last authentic sighting was in fact by Eric Zillmann in 1938 in the Gin Gin area of the Burnett Valley.
Marbled Frogmouth. In 1979 it was thought to be “rare” in the rainforests of the Conondale Range. This was relatively not long after I rediscovered the plumiferus race of the species in the Conondale Range in 1976. It can best be described as uncommon today though moderately common in suitable habitat. It is known also from various sites extending from the McPherson Range in the south to Cooloola in the north.
Large-tailed Nightjar. It was also considered “rare” in 1979 and confined to northern areas – Gin Gin, Bundaberg and “probably” Fraser Island. It continues to be regarded as scarce but is known to occur further south to Rainbow Beach, Cooloola and more recently, the Sunshine Coast.
