This is the third post demonstrating changes in the status and
distribution of birds in South-East Queensland over the 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).

Australian Brush-turkey |
Australian Brush-turkey. Described as “moderately common”
in 1979, it is regarded today as common, and locally very common. The
species has clearly benefited from the greening of Brisbane's outer
suburbs and other urban areas.
Red-backed Buttonquail. In 1979 it was recorded as “rare”,
known from agricultural crops in the Lockyer Valley and rank
vegetation near Gin Gin. It is today still regarded as scarce but has
been recorded regularly from mid-to-tall grassland, wallum heathland
and crops, especially sugarcane, in several areas including
Maryborough, the Sunshine Coast and Lake Samsonvale.
Lewin's Rail. In 1979 it was thought to be “rare”, with
specimens and sightings from a small number of sites. It is now known
to be uncommon generally and moderately common in some areas. It is
also known to frequent a much wider range of habitats than was
previously thought to be the case.
|
Spotless Crake |
Spotless Crake. Another species described in 1979 as
“rare”, it is today known to be moderately common in suitable
habitat and is the most numerous crake in the region. Like the
previous species, records have doubtlessly increased due to the
growing popularity of playback, but both can be quite vocal and it is
unlikely so many records were overlooked previously.
|
Black-tailed Native-hen |
Black-tailed Native-hen. Known in 1979 from a single
sighting, at Redcliffe in 1973. It has since been recorded in small
numbers on several occasions from around Brisbane, the Sunshine
Coast, and the Lockyer and Brisbane valleys.
|
Australian Bustard |
Australian Bustard. It was thought to be extinct in
South-East Queensland in 1979, though known historically from western
and northern parts of the region. It remains very rare but has been
recorded as a vagrant from a handful of sites including Monto,
Maryborough and the Gold Coast.
|
Sooty Oystercatcher |
Sooty Oystercatcher. Described as “rare” in 1979, it is
known now to be uncommon though widely distributed on coastal rocky
outcrops.
Banded Stilt. In 1979 the occurrence of this species in the
region was unconfirmed, with reported sightings “almost certainly”
immature Pied Stilts. There has since been a single confirmed record,
from Lake Clarendon.
|
Red-necked Avocet |
Red-necked Avocet. The species was thought to be “rare”
in 1979, known from a handful of sites. It was unknown at the time
from areas such as the Lockyer Valley and parts of Moreton Bay where
it is now known to be moderately common if irregular.
|
Asian Dowitcher |
Asian Dowitcher. In 1979 it was known from a single
sighting at Wynnum. It is now considered a rare summer visitor though
is recorded regularly from several sites.
|
Pectoral Sandpiper |
Pectoral Sandpiper. Like
the previous species it was considered a vagrant in 1979, known from
two records. It is similarly known now to be a rare summer visitor
though recorded regularly in suitable habitat.
|
Great Knot |
Red Knot & Great Knot. Red
Knot in 1979 was thought to be “moderately common to common”
while Great Knot was “generally uncommon, though locally common”.
The reverse could today be regarded as more accurate, with Great Knot
greatly outnumbering Red Knot. Furthermore, unlike the
Great Knot, the Red Knot is
more numerous in the region
as a transient migrant, with
relatively few spending the summer here.
|
Curlew Sandpiper |
Curlew Sandpiper. The
species was thought to be “very common” in 1979. It can best be
described as “moderately common” today with numbers declining
notably. This is one of many migratory shorebirds to suffer from the
destruction of feeding
habitat in east Asian flyways.
Ruff. Another “vagrant”
in 1979, it was known from a single sighting at Dyers Lagoon.
Although still fairly described as vagrant, there have since been a
number of sightings from the
region.
|
Pomarine Jaeger |
Pomarine Jaeger. This
bird was considered an “uncommon” summer
visitor in 1979 but we now know it be quite common in offshore
waters.
Long-tailed Jaeger.
Considered “rare” in 1979, with several autumn sightings from
North Stradbroke Island, it
is today seen uncommonly but regularly in offshore waters.
Pacific Gull. Records of
the species in 1979 were unconfirmed in the region but it
is now confirmed as a vagrant.
|
Sooty Tern |
Sooty Tern & Bridled Tern.
Sooty Tern in 1979 was known from about 30 beach derelicts but no
sightings, while Bridled Tern was considered “rare”, with a
very small number of
sightings off North Stradbroke Island. The
Sooty Tern is regularly seen
in offshore waters these days and while still uncommon, the
Bridled Tern is reported irregularly from inshore and offshore
waters.
White Tern. It was a “vagrant” in 1979, known from four
sightings. Many more sightings have since been recorded, though it still is
regarded as a rare visitor.
