Nine transects in south-east Queensland were censused eight times over two years to determine
relative abundance of bird species and their distribution between roadside softwood scrub remnants
and eucalypt associations. Eighty-eight species were observed; 80 in the softwood scrub and 56 in
the eucalypt associations, with 48 common to both habitats. On average, 50 individual birds (42 ha-1)
were observed in each census of the softwood scrub remnants and 21 (18 ha-1) in the eucalypt
associations.
Silvereye, Double-barred Finch, Superb Fairy-wren, Willie Wagtail and Lewin's Honeyeater were
the most frequently observed species in the softwood scrub, with Double-barred Finch (mean of 8.9
individuals per census), Zebra Finch (6.5), Silvereye (5.2), Superb Fairy-wren (3.4) and Lewin's Honeyeater
(1.6) most abundant. In the eucalypt associations, Noisy Miner, Black-faced Cuckoo-shrike, Grey
Butcherbird, Rufous Whistler and Lewin's Honeyeater were most frequently observed, with Noisy
Miner (7.4), Scaly-breasted Lorikeet (1.5), Grey Butcherbird (1.0), Pale-headed Rosella (0.8) and
Rufous Whistler (0.6) most abundant.
