Bell, H.L. & H.A. Ford.  1987.  Fidelity to breeding-site in four migratory species near Armidale, New South Wales.  Corella 11: 1-5.

Rufous Whistlers Pachycephala rufiventris and Leaden Flycatchers Myiagra rubecula are breeding visitors to the area.  Some individuals return to the same territory in successive years.  Yellow-faced Honeyeaters Lichenostomus chrysops and Silvereyes Zosterops lateralis are common passage migrants and winter visitors.  Both have small breeding populations near Armidale and remain within, or return to, the same territories in subsequent years.

Marchant, S..  1987.  Territorialism and co-operative breeding of the eastern Yellow Robin Eopsaltria australis. Corella 11: 6-14

I studied the Eastern Yellow Robin Eopsaltria australis from 1975 to 1986 near Moruya, N.S.W.  The birds were distributed in territories of 1 to 2 hectares.  A fire in 1980 did not at once reduce breeding numbers; they declined next season.  Established pairs held territories while breeding.  In the non-breeding season they lived in the same areas but were not seen to defend territories.  Some first year birds also bred, almost always without success; having attempted to breed, these pairs then dispersed.  Others attended the nests of their parents or near neighbours.  These attendants were first-year males.  First-year females were unobtrusive and were not known to act as attendants.  Mildly threatening disputes within territories early in the breeding season were probably directed towards evicting unwanted immature birds by established pairs.  Attendants were attached to only about one fifth of the annual breeding attempts.

Dunlop, J.N.  1987.  Moult and breeding in the Common Noddy Anous stolidus on Christmas Island Indian Ocean.  Corella 11: 15-19.

Common noddies on Christmas Island in the Indian Ocean were captured at a social roost during the breeding season and their primary moult and brood-patch condition was examined.  Early in the attendance period at the roost (May), few noddies showed evidence of either breeding or primary moult and very few individuals were engaged in both activities.  Most noddies had started to moult by June and many were incubating and moulting simultaneously.  The number of noddies incubating peaked in early July when almost all breeding birds showed active wing moult.  Moult was not completed during the main laying period.  Although moult overlapped with breeding, it did not advance beyond the third primary in pre-laying or incubating noddies.  However, it had resumed in birds with re-feathering brood-patches, many of which were rearing chicks.  The extensive overlap between moult and breeding in July presumably corresponds to a period when the nutritional and/or energy requirements for both activities can be met by the food resources.  However, moult was arrested in pre-laying and incubating birds, possibly because of the nutritional and/or energy cost of the early stages of the nesting cycle.

Hnatiuk, S.H.  1987.  Numbers of Waterbirds at a swamp in Ferndale, Western Australia, 1978 to 1981.  Corella 11: 20-27.

Weekly counts of waterbirds on a small swamp were made from January 1978 to May 1981.  Three species accounting for 67% of the birds counted were the Eurasian Coot (33%), Pacific Black Duck (23%), and Grey Teal (11%).  Greater numbers of birds were observed during the summer months than at other times of the year.  Species showing significant seasonal variation in numbers were the Eurasian Coot, Pacific Black Duck, Grey Teal, Australian Shelduck, and Little Black Cormorant; those with more constant numbers throughout the year were the Hardhead, Dusky Moorhen, and Australasian and Hoary-headed Grebe.  Variations between years in the pattern of fluctuating numbers were noted and some of the variations may be related to events such as drought.

van Frankener, J.A. & T. Montague.  1987.  Recoveries of Petrels banded near Casey Station, Wilkes Land, Antarctica, 1984 to 1985. Corella 11:32-43

Banded birds were recovered during a study of fulmarine petrels near the Australian Antarctic station Casey, in the summer of 1984-1985.  Fourteen Southern Fulmars, banded from 1961 to 1963, were retrapped at Ardery Island.  Twenty-three Snow Petrels, banded in 1979 and 1980, , were retrapped Reeves Hill close to Casey.  Two Antarctic Petrels and one Snow Petrel, banded elsewhere were recovered at Ardery Island.  A Cape Petrel was recovered dead.  Recaptures permit some minimum estimates for age and survival, age of first breeding, fidelity to mate and nest-site and provide evidence of chicks becoming established in both natal and other colonies.

Lashmar, A.F.C.  1987.  Silvereyes Zosterops lateralis on Kangaroo Island, South Australia.  Corella 11: 44-51.

A 13 year study of Silvereye populations on Kangaroo Island provides an insight into the dispersal patterns of Sivereyes in the S.A. region.  Only nine confirmed movements of birds between Kangaroo Island and the mainland of S.A. were recorded even though retrap data clearly indicates a movement of birds away from the banding site in winter and spring.  The Silvereyes that were resident on Kangaroo Island are not distinguishable from the S.A. mainland birds in terms of morphometrics or plumage.  Only two "Tasmanian" plumage birds were captured on Kangaroo Island during the course of the study.

Nearly 3000 Eastern Spinebills have been banded in New England National Park since 1977.  The number of birds caught each year was greatest in winter (April-September) when two Banksia species were in flower.  Each year there was a number of peaks in birds captured, possibly due to successive invasions of either different spinebill populations or different parts of the same population.  A total of 134 (5.2%) birds were recaptured in a subsequent year, often in the same month that they were banded.  The oldest bird was at least 8 years old, and survival was estimated to be 60% per year.  During the year the sex ratio of the population changed, with males outnumbering females in most months but particularly so in March, July and August.

The results of a three year survey of Little Tern breeding colonies are presented.  Details of reproductive success, nests, clutch size, threats to breeding success and management techniques are discussed.  The presence of eclipse plumaged birds is noted and briefly discussed.

Tarburton, M.K.  1987.  The population status, longevity and mortality of the White-rumped Swiftlet in Fiji.  Corella11: 97-110.

The population size of the White-rumped Swiftlet Aerodramus spodiopygius in five Fijian caves has been estimated by up to five methods.  The averages of these methods for 1974 are: Dry Cave, 413; Waterfall Cave, 20 994 Ono Cave, west entrance, 345; east entrance, 10 365; Waiyala Cave, 8 430; Cikobia-i-lau, 210.  The largest annual average estimated population was 32 526 for Waterfall Cave in 1975.  Although the population of Dry Cave declined between 1974 and 1983 the recapture rate of marked birds remained high.  These data show an average survival rate of 64%, though a survival rate of 73% (which is determined when data taken in the abnormal years of 1976 and 1982 are deleted), may be more realistic.   The higher rate, which gives an adult further life expectancy of 3 2 years is higher than most passerines, some seabirds and one other species of swift.  Higher adult life expectancies have been shown for four other swift species.  Juvenile mortality is shown to be too high to replace the adult population and it is reasoned that human interference in Dry Cave is responsible for the high juvenile mortality.  Adult mortality is low and arises from predation and accidents caused by conspecifics.   The current longevity record in this study is at least 12 years.

Paton, D.C., & P.A. Paton.  1987.  Olives and their effect on the plumage of Spotted Turtle-Doves Streptopelia chinensis and Crested Pigeons Ocyphaps lophotes in suburban Adelaide.Corella11: 111-115.

During winter Crested Pigeons Ocyphaps lophotes and Spotted Turtle-Doves Streptopelia chinensis often develop dark-brownish plumage in suburban Adelaide.  Up to 80 per cent of pigeons and doves censused in the Gilberton area developed darker plumage  This darkening coincided with the presence of European olives Olea europea in the birds‚ diets.  We argue that these pigeons and doves splash olive oil and an associated dark-purplish pigment onto their feathers while tearing chunks of mesocarp from fallen olives.   Captive birds fed on a diet that included ripe olives developed the dark plumage while birds fed only on grain did not.  Birds fed mainly on olives also lost weight.
