Rowley, I. & D.A. Saunders.  1980.  Rigid wing-tags for Cockatoos.  Corella 4: 1-7.

Between 1970 and 1975, 1 128 Galahs and 685 White-tailed Black-Cockatoos were marked with wing-tags so that the birds could be individually identified without resorting to re-trapping.  Tags have been worn by some cockatoos for eight years and do not appear to have interfered with their behaviour or reproductive success.  Similar wing-tags have been used on Long-billed Corellas, Little Corellas, Red-tailed Black-Cockatoos and Pink Cockatoos.

Bell, H.L.  1980.  The effects of a power-line clearing on birds of Dry Sclerophyll forest at Black Mountain Reserve, Australian Capital Territory.  Corella 4: 8-19.

Census counts were made in dry sclerophyll forest. and a clearing along a power-line, at Black Mountain Reserve, A.C.T., on 156 days between March 1974 and April 1975.  There were seasonal changes in both species and numbers in each site.  There were more species and individual birds in the clearing than in the forest.  Most of the forest birds used the clearing and five additional species colonised it.  Colonists were mainly small passerines inhabiting dense undergrowth.  Some species found in the clearing would not have been recorded if there had not been adjacent forest.  The enrichment would almost certainly not apply to large tracts of cleared dry sclerophyll forest, nor wouhd it have occurred in this case but for the management policies of the Reserve authorities.

Potential uses of captive raptors for research are discussed.  A selection of papers on incubation, clutch size, fertility, photoperiod, eggshell thinning and DDT, taxonomy, general biology, development of young, visual acuity, veterinary aspects, plumage changes and metabolism is reviewed.

Marchant, S.  1980.  Incubation and nestling periods of some Australian Birds.  Corella 4: 30-32.

Incubation and nestling periods of Australian birds, particularly small passerines, seem not to have been much studied and in general are not known accurately.  Details of incubation and nestling periods, collected for 25 species at Moruya, New South Wales, are presented.

Observations on Eurasian Coots Fulica atra, breeding near Manjimup, Western Australia, between 1975 and 1978, are given together with details of average clutch size, replacement clutches, predation and mortality.  Nest sites, construction and nesting materials are discussed.

Noske, R.A.  1980.  Co-operative breeding and plumage variation in the Orange-winged (Varied) Sitella.  Corella 4: 45-53.

Observations were made at a nest attended by six Orange-winged (Varied) Sittellas, three of which were colour-banded near Armidale, New South Wales.  The nest was watched for 15 hours, which included late incubation and nestling periods.  Only one bird, a female, incubated and brooded.  Five group members, including two juveniles from a previous brood in the same season, fed the nestlings and removed faecal sacs.  The sixth bird, an adult female, was apparently discouraged from feeding by the incubating bird.  The primary pair contributed over half the total feeding effort by the group.  Observations at other nests prove that both sexes build, and that incubating females are fed frequently during the incubation period by other members of the group.  Allopreening is described and roosting behaviour suggests the operation of a social hierarchy within the group.  The sex ratio of the group studied was even, but males out-number females in most groups.  Sexual dimorphism appears to exist in young sittellas, but adults may be indistinguishable by plumage alone.  Juveniles are characterized by white markings on the upperparts but this is lost within the first few months.  Buff edging on the wing-coverts, particularly secondary coverts, lasts at least eight months on some birds and this character is most useful in recognising first year birds.

Olsen, J. & P. Olsen.  1980.  Alleviating the impact of human disturbance on the breeding Peregrine Falcon II. Public and recreational lands.  Corella 4: 54-57.

Some potential sources of breeding disruption to Peregrine Falcons are outlined.  Though adequate legislation exists and there are many opportunities to protect eyries, little is being done at present.  Research, education and planning can help to minimise disruption.

Bell, H.L.  1980.  Foraging ecology, territoriality and seasonality of the Common Paradise Kingfisher at Brown River, Papua New Guinea.  Corella 4: 113-126.

Data on the kingfisher Tanysiptera galatea, taken at Brown River, Papua New Guinea, are presented.  The species forages almost entirely in the lower understorey of rainforest or on the ground, with pronounced seasonal change involving foraging at lower levels during the wet season.  Food observed was earthworms, large insects and a lizard, the worms being probed for in the ground.  Population density is estimated at 50 birds/10 ha.  The adults are monogamous, remain paired, hold territory year-round and are extraordinarily sedentary.  Territories average about 0.3-0.5 ha.  Breeding occurs within the wet season in contrast to other kingfishers in the same area, which commence breeding prior to the wet season.  Considerable intraspecific aggression occurs prior to breeding and three possible agonistic displays are described.  The nest is tunnelled into arboreal termiteria on lower trunks.  In contrast to adults, immatures have high dispersal ability. Lack of food resources are considered to be as important as aggression by adults in contributing to dispersal.  Annual adult mortality is at most 25-33% and probably much less, while annual increment of independent young is at least 150%.  Moult occurs after breeding and takes two months or less.  Immatures attain adult plumage probably 3-4 months after fledging.  The bird is considered well-adapted to cope with waxing and waning of suitable habitat.

Lamothe, L.  1980.  Birds of the Araucaria Pine plantations and natural forests near Bulolo, Papua New Guinea.  Corella 4: 127-131.

A comparison of birds found in natural and plantation Araucaria (Hoop and Klinkii Pine) forests in the Bulolo area of Papua New Guinea led to the conclusion that, within the plantations, certain major groups of birds were missing.  This may be due to a lack of specialised niches for these birds.  Maturation of the plantations may result in these niches becoming available.
