1. Feeding behaviour of koalas (Phascolarctos cinereus) was observed at a sanctuary near Brisbane, Australia. They fed sporadically throughout the day, for a total of at least 19 h daily, on leaves; they ingested soil and gravel, and drank water when it was provided, but infrequently. Young were seen to leave the pouch at 220 days old and to eat leaves at 217 days old. None under 10 months old was seen to pull leaves forward before biting them.

2. Young koalas (Phascolarctos cinereus) began to eat leaves after they left the pouch but before they left the mother's back. The oldest seen sucking was about 13 months old and small for its age. Young koalas still in or returning to the pouch, one of them 240 days old, were seen to eat faeces directly from the mother; adults did not practise coprophagy.

Central Australia

The behaviour was observed, in captivity, of the bilby Macrotis lagotis, a fossorial bandicoot of central Australia. Most of the observations were made at night, but some were of below-ground behaviour during the daylight hours. Bilbies proved to be relatively passive in comparison with other bandicoots, and a rigid dominance hierarchy amongst males was maintained without destructive fighting. Dominant males chased subordinate males out of and away from burrows and the alpha male maintained priority of access to all the well used burrows in the enclosure. Males scent-marked around burrows; the dominant male usually marked over scents left by other bilbies. Males shared burrows freely with females, and copulation appears to take place down burrows. Information is also given on female-female and mother-young behaviour, and some suggestions are made concerning the social structure of wild bilbies. Activity cycles, feeding behaviour, etc. are described.

Nutritional Conditions

AbstractUnder poor nutritional conditions, 3rd instar Drosophila melanogaster larvae will work collaboratively in feeding clusters to obtain resources that cannot be reached individually. To better understand the conditions that influence the expression of this behaviour we examined the frequencies, the size and the membership in vials of flies that were initially seeded with either 100 or 200 eggs each using flies from both a large, outbred population and a replicate population that was homozygous for the bw allele. Overall, more feeding clusters, containing more larval participants were observed in the higher density vials compared to the lower density vials, consistent with the idea that this social behaviour is a response to dwindling resources in the environment. The presence of the bw allele did not result in greater egg-to-adult mortality, nor did it result in lower participation in feeding clusters.

Present research was planned to evaluate the breeding and feeding behaviour of Indian peafowl reared in captivity at Zoological Gardens of Government and Private Sector. For feeding behaviour, a total of fifty pairs (n=100) of Pavo cristatus at both Government Zoological Gardens (n=25pairs) and Private Sectors (n=25pairs) were observed on daily basis. The breeding season of Indian peafowl is not fixed but mostly it breeds in rainy season from April to August. It was observed that most of birds at Government Zoological Gardens breed in month of May, while most of birds at Private Sectors breed in the month of August. For feeding behaviour a total of 200 faecal samples per week were collected for six weeks, out of which 100 samples per week were randomly selected for further analysis. Faecal analysis technique showed that dietary components of Indian peafowl were covered by plant contents following by animal sources. Among the plants components grass seeds were predominant followed by dicotyledon and fruits with least portion of monocotyledons. Among animal components, ants, grasshopper, earthworms, spider and unidentified bones were present. Faecal analysis indicated the presence of some non-food items such as sand and gravel.

'In a colony of captive koalas, all aggressive behaviour was a variation on the single motor pattern of throwing a foreleg around an opponent and biting. Squabbles (the most common aggressive behaviour) were brief, low level interactions usually arising from the efforts of one koala to climb past or over another. Minor fghts involved only single bites and the combatants stayed in the same place; major ,fights involved multiple bites and changes of position. Dependent young were seldom involved in aggression. Between males. minor fights were essentially intensified squabbles, but major fights involved wrestling and chasing; they were more likely between males unfamiliar with each other, or those already aroused by, e.g., other aggressive interactions. Females became aggressive especially during pregnancy and at the end of lactation. At such times they stood their ground and vocalized at other koalas, especially males, but attacked only if the opponent came within reach. Although the opponent usually withdrew. sometimes a male seemed provoked to attack. Males sometimes attacked females without obvious provocation. Aggression was slightly more common in than outside the breeding season. Competition for females or food, dominance hierarchies, appeasement, and the defence of young were not seen.

Agonistic Encounters

Male koalas scent-mark by grasping a vertical object, generally a tree, and rubbing the sternal gland against it. The behaviour first appears at 3 y of age, and reaches a peak a year or two later. It is frequently performed in conjunction with bellowing, especially in response to agonistic encounters or the bellow of a rival male, and often by itself in circumstances where a bellow might be expected. It is sometimes a response to unfamiliar surroundings or objects, and otherwise is performed by a male moving about a pen. Scent-marking may primarily be a response to unfamiliarity which, having become associated with displaced aggression, has been entrained to the bellowing drive.

Behavioural Repertoire

The behavioural repertoire of Macropus rufus in captivity is described in comparison with data from literature. Most behavioural elements observed do not differ from those of free-ranging populations. Some new elements of agonistic and sexual behaviour are described. The sequential organisation of adult social behaviour allows a distinction between the functional categories of agonistic, friendly and sexual behaviour as well as a series of transitional elements. In sexual behaviour, low-intensity sexual checking can be distinguished from high-intensity courting and mating behaviour. In agonistic contexts a distinction between elements of ritualised and unritualised fighting is possible on the basis of sequences, with fixed sequences of behaviour patterns in ritualised fighting. Young M. rufus show nearly all behaviour patterns of adults, though frequently out of context. Their behavioural repertoire is not organised into different functional categories. Playfighting as well as running-play are not restricted to the mother-young dyad.
