Young domestic chicks of two strains, ISA brown layers and White Leghorn X Australorps, were trained to associate a magnetic anomaly with food. This was done by feeding them in their housing boxes from a dish placed above a small coil that produced a magnetic anomaly roughly six times as strong as the local geomagnetic field. Unrewarded tests began on day 9 after hatching. In a square arena, two corresponding coils were placed underneath two opposite corners. One coil, the control coil, was double-wrapped producing no net magnetic field, while the other in the opposite corner produced a local magnetic anomaly similar to that experienced during feeding. The chicks favoured the corner with the anomaly from day 10 after hatching onward. Both strains of chickens showed this preference, indicating that they could sense the local changes in the magnetic field.
Little is known about the movements of Australian birds. Information is particularly scarce on large, aquatic birds, which are usually difficult to access and handle. Their movements are also often complex, and therefore difficult to Identify. Here we present data on the local and long distance movements of the Australian White Ibis Threskiornis molucca, a highly mobile bird, which as many other waterbirds, continues to decline In its traditional ranges in inland Australia. At the same time it has invaded coastal urban environments, where its high abundances cause many problems and require management. Our analysis of past and present banding studies reveals that Australian White Ibis travel throughout the urban environment and visit landfills, where they forage in large numbers. They also conduct long distance movements, which lead birds from breeding sites In south-eastern Australia along the eastern coast to regions further north (Queensland and Papua New Guinea). Young birds return to their hatching site, when sexually mature. Their preferences for landfills, high mobility, complex movements and current decline in inland Australia need to be considered, when developing and implementing management strategies for Australian White Ibis and ecologically similar birds.

We recorded the locomotor activity of the partially migratory Tasmanian silvereye, Zosterops l. lateralis, and the nonmigratory mainland silvereye, Z. l. familiaris, continuously over 17 and 15 months, respectively, to identify daily and seasonal patterns. While graphing the data showed several trends, statistical analysis did not reveal a significant difference between subspecies, making this study mainly descriptive in nature. The lack of statistical differentiation was possibly due to the low number of study animals and similarities between them. During the first year in captivity, the Tasmanian birds displayed heightened activity during the migratory periods, which was most likely migratory restlessness. The Tasmanian birds did not show any nocturnal activity as in previous laboratory and field studies, rather their activity patterns were similar to those of diurnal migrants, possibly reflecting the temporally variable nature of their migration. Although the Tasmanian birds displayed higher overall activity levels than the mainland birds during the first year in captivity, the activity patterns were similar between the subspecies. Captivity appeared to influence the activity of both subspecies in the second year of the study; following the onset of molt, neither subspecies regained the activity levels of the previous year, nor did activity follow the same pattern. Possible reasons (e.g., prevention of breeding) for this are discussed. This is the most detailed study to date on the daily and seasonal activity patterns of an Australian bird in captivity.

Migratory silvereyes treated with a strong magnetic pulse shift their headings by approximately 908, indicating an involvement of magnetite-based receptors in the orientation process. Structures containing superparamagnetic magnetite have been described in the inner skin at the edges of the upper beak of birds, while single-domain magnetite particles are indicated in the nasal cavity. To test which of these structures mediate the pulse effect, we subjected migratory silvereyes, Zosterops l. lateralis, to a strong pulse, and then tested their orientation, while the skin of their upper beak was anaesthetized with a local anaesthetic to temporarily deactivate the magnetite-containing structures there. After the pulse, birds without anaesthesia showed the typical shift, whereas when their beak was anaesthetized, they maintained their original headings. This indicates that the superparamagnetic magnetite-containing structures in the skin of the upper beak are most likely the magnetoreceptors that cause the change in headings observed after pulse treatment.

Previous research has shown that the ability to orient with the use of directional cues from the geomagnetic field is lateralized in three avian species: orientation is possible when the birds are restricted to use of their right eye, but not when they have to use their left eye. This has been interpreted as possible lateralization of the perception mechanisms for magnetic cues in favour of the right eye. Recent discovery of magnetic compass orientation in domestic chicks, a species in which lateralization has been well studied, has made available a model system in which to explore these lateralized processes more fully. Hence we tested chicks monocularly in the same test conditions as used previously to demonstrate the chick's use of a magnetic compass. In a magnetic field with North shifted by 90 degrees, chicks using their right eye oriented according to magnetic cues, whereas chicks using the left eye did not. but continued to prefer the original direction. Analysis of the times taken to respond indicated longer latencies in the chicks using their left eye, suggesting a possible conflict between cues. The different behaviour of the chicks using their left eye might not be a matter of a right eye-left hemisphere specialization for detecting magnetic directions, but of hemispheric specialization for attending to specific types of cues.

Previous studies have shown that a magnetic pulse affected the orientation of passerine migrants for a short period only for about 3 days, the birds' headings were deflected eastward from their migratory direction, followed by a phase of disorientation, with the birds returning to their normal migratory direction after about 10 days. To analyse the processes involved in the fading of hte pulse effect, migratory birds were subjected to a second, identical pulse 16 days after the first pulse, when the effect of that pulse had disappeared. This second pulse affected the birds' behaviour in a different way: it caused an increase in the scatter of the birds' headings for 2 days, after which the birds showed normal migratory oreintation again. These observations are at variance with the hypothesis that the magnettite-based receptor had been fully restored, but als with the hypothesis that the input of this receptor was ignored. They indicate dynamic processes,w hich include changes in the affected receptor, but at the same time cause the birds to weigh and rate the altered input differently. The bearing of these findings on the question of whether single domains or superparamagnetic particles are involved in the magnetite-based receptors is discussed.

The Australian White Ibis Threskionis molucca is very successful in adapting to and surviving in urban environments. Overaundant and/or large, permanent populations have established in many urban areas of coastal eastern Australia. In urban areas, the Australian White Ibis is currently regarded as a major pest and many agencies aim to reduce it numbers, however,the lask of knowledge on this species has made management difficult.Inthis study clutch size and fledgling success of Australian White Ibis breeding in Centennial Park, a large urban park in Sydney, were measured. Mean clutch size was 2.70 with a modal clutch size of three. Mean number of fledglings per successful (nestlings hatched) nest was 2.64. While clutch sizes were similar to those reported for ibis in natural and non-urban environments, fledgling success was considerably higher in Centennial Park. This is most likely due to high food availability in urban areas. management of artificial food sources 9eg. landfills) might be necessary for successfully managing ibis in urban environments.

The grey-headed flying fox (Pteropus policephalus Temminck) is a threatened large fruit bat endemic to Australia. It roosts in large colonies in rainforest patches, mangroves, open forest, riparian woodland and, as native habitat is reduced, increasingly in vegetation within urban environments. The general biology, ecology and behaviour of this bat remains largely unknown, which makes it difficult to effectively monitor, protect and manage this species. The current study provides baseline informationn o the daytime behaviour of P. poliocephalus in an autumn.winter roost in urban Sydney, Australia, between April and August 2003.

The Regent Honeyeater Xanthomyza phrygia is an endangered species that has caused great concern in recent years due to its sharp decline in abundance (Menkhorst et al. 1999). Althugh a number of studies have been conducted on the biology and behaviour of this species (Franklin et al. 1989; Webster and Menkhorst 1992; Oliver 2000), there is very little data available describing its moult (Higgins et al 2001). In most species with seasonal movements, moult typically precedes movements (Ginn and Melville 1983). Therefore, the moulting patterns of this species may be of particular interest as knowledge on the timing of moult may indirectly ais in understanding the timing of the birds' seasonal movements. In this study, the sequence of post-breeding moult in captive adult and immature Regent Honeyeaters is documented and whether immature birds moulted ona similar timescale to adults.

To test the hypothesis that single domain magnetite is involved in magnetoreception, we treated Australian silvereyes Zosterops l. lateralis with a strong, brief pulse designed to alter the magnetization of single domain particles. This pulse was administered in the presence of a 1 mT biasing field, either parallel to the direction of the biasing field (PAR group) or antiparallel (ANTI group). In the case of magnetoreceptors based on freely moving single domain particles, the PAR treatment should have little effect, whereas the ANTI treatment should cause remagnetization of the magnetite particles involved in a receptor and could produce a maximum change in that receptor's output for some receptor configurations. Migratory orientation was used as a criterion to assess the effect on the receptor. Before treatment, both groups preferred their normal northerly migratory direction. Exposure to the biasing field alone did not affect their behavior. Treatment with the pulse in the presence of the biasing field caused both the PAR and the ANTI birds to show an axial preference for the eastwest axis, with no difference between the two groups. Although these results are in accordance with magnetite-based magnetoreceptors playing a role in migratory orientation, they do not support the hypothesis that single domains in polarity-sensitive receptors are free to move through all solid angles. Possible interpretations, including other arrangements of single domains and superparamagnetic crystals, are discussed.
