Kangaroos are marsupials and belong to the Family Macropodidae (i.e. Big feet) that is grouped with the Potoroidae (potoroos, bettongs, rat-kangaroos) and Hypsiprymnodontidae (musky rat-kangaroo) in the Super-Family, Macropodoidea. This comprises around 50 species in Australia and a dozen or more in New Guinea. Some of the smaller species, such as Yellow-footed Rock-Wallabies, Burrowing Bettongs, accompanied Pig-footed and Golden Bandicoots, Bilbies and possibly Hairy-nosed Wombats into extinction with the advent of pastoralism.

All terms used in this manual are described in the glossary of terms at the end of this document. Introduction Macaws are the largest, most fascinating birds of the parrot family (Psittacidae). The macaw group consists of 17 different living species that are divided up into 4 genera. These are Ara, Diopsittaca, Andorhynchus and Cyanopsitta.

However, the largest species remain in much of their original range with the grey kangaroos expanding inland as grazing habitat increased and coastal habitat was lost in clearance for agriculture. The defining feature of the kangaroo family is that they are the largest vertebrates to hop (both currently and from what we know from palaeontology).The Pademelons are small, compact, short-tailed wallabiesthat typically inhabit wet sclerophyll and rainforests from Tasmania to NewGuinea. The genus is equally diverse in New Guinea (4 species) and Australia (3species) with one of the latter, the Red-legged Pademelon ( T.stigmatica), in both regions.

The Pademelons occupy an interesting taxonomicposition and may have been the ancestors of both Tree-kangaroos andRock-wallabies a few million years ago. Given the absence of Rock-wallabies fromNew Guinea but presence of Pademelons in both Australia and New Guinea,Tree-kangaroos likely evolved first, probably in New Guinea, and two speciesentered the far north through Cape York. Rock-wallabies evolved later inAustralia, probably on the east coast where Pademelons are found, and when nosuitable habitat breached the Torres Strait or Bass Strait given their absencefrom Tasmania.Reddish coloured fur is something of a themewith red-bellied, red-necked and red-legged in the species common names. Theyemerge from forest cover at night to eat succulent grasses and take some browse.They have remained common over much of their geographic range but the TasmanianPademelon was once found in south-eastern South Australia and Victoria.

Densethickets of vegetation are required for shelter and so habitat fragmentation andclearing reduce the viability of populations.Red-necked PademelonThylogale thetis ('Thetis's Bougainville's ship pouched-weasel')New South WalesBarrington Tops National Park is 263 km and about 4.5 hours drive from Sydney.The Park is formed from an ancient volcano and rises to over 1500 m above sealevel. It is part of the Gondwana Rainforests of Australia World Heritage Area.Thus it contains sub-tropical rainforest but the plateau is sub-alpine forestand snow is common in winter. Most of the Park is wilderness and there areextensive walking trails. The Park is divided into a number of sections and hasextensive visitor facilities. The two main fully serviced campgrounds are at theGloucester River and Polblue.

There are a number of other bush camping sites inthe Mt Barrington section and Devils hole and day visitor facilities in eachsection. There are also private accommodations near the Park boundaries.The Park has a rich macropod fauna that also includes the,.Males to 9.1 kg (average 7.0 kg) and females to 4.3 kg (average 3.8 kg). TheRed-necked Pademelon has moderate build between the slender Red-legged Pademelonand the robust Tasmanian Pademelon.

The medium length fur is thick and soft;the underfur is long and grey. The overall colour is a grizzled grey, but thespecies derives its common name from the red-brown on the shoulders. The headis a uniform grizzled grey colour and lacks a dark dorsal stripe. The ears arelong and their backs are grey with brown or black edge. Some individualsexpress a faint white hip stripe but it is usually lacking.

The undersides (thechin, chest and abdomen) are white, and well-defined from the upper bodycolour. The arms and legs vary from grey to red, and the hands and feet arepale brown.

The base of the tail is grey, like the back, but the rest is brownabove and white below. The tail is held like a stiff rod when hopping unlike theParma Wallaby that can be found in the same habitat.The Red-necked Pademelon prefers the ecotone between forest and grassy patchesor pasture.The rest and forage in the forest and then follow well-defined pads out toadjacent grasslands to forage mainly at night. They rarely emerge morethan about 100 m from the forest edge but may penetrate the forest to 500 m ormore. In the northern part of its range it is sympatric with.The diet ofthe Red-necked Pademelon is many short grasses and herbs but they will browsefrom some shrubs.

They can be activethroughout the day and night with a deeper rest period around midday through tomid-afternoon. In the day they forage in the shelter of the forest andemerge onto open habitat out from the forest edge at nightfall returning toshelter by dawn. In cooler weather they may bask in open patches in the forest.The reproductive physiologyof the Red-necked Pademelon is less well studied than the other Pademelons. Breeding iscontinuous with birth peaks in the autumn and spring.

The pouch life isaround 6 months. The length of gestation isnot currently known and there is a suggestion that oestrus may not be post-partum oestruswith an interval up to 7 days between birth and the next fertilisation. Embryonic diapausehas not yet been determined. Young are weaned at about 9 months.

Females mature at 12 monthsin captivity but more like 17 months in the wild.The species issexually dimorphic with males larger and more muscular in the forelimbs andchest than females. Males court females with a soft clucking vocalisationtypical of many macropods. In captivity, females given a choice between small,medium and large males chose the latter as the approached and entered oestrus.They also associated strongly with males when in oestrus even though they didnot have physical contact. Thus in aggregations in the wild, females mayexercise mate choice and be most receptive to large males and make seek them outwhen in oestrus.In aggressive encounters within and between the sexesa guttural growl vocalisation is uttered. Individuals are usually solitary butmay aggregate in relatively large numbers on nocturnal foraging areas where social interactions may occur.Home ranges are relativelylarge at 5-30 ha and include distinct daytime areas in the forest and smallernight-time areas on pasture at the forest edge.

The Pademelons stay in or closeto cover at all times and rarely venture more than 100 m from the forest edge.They are hunted by dingoes and foxes. Individuals are usually solitary in the forest butmay aggregate in loose intermingling groups of 10 or more at night when in open habitat.Group size increases with distance from the forest edge and thereby individualpademelons do not increase their vigilance. Xg 760n sagem driver for mac. Vigilance and foraging arenegatively correlated and vigilance increases as a function of perceived risk; i.e.greater in small groups and longer distances from cover. Alarmed individualsfoot thump and groups scatter back into the forest. Red-necked Pademelons whenpresented with a synthetic dog urine spent time inspecting the site rather thanavoiding it. This contrasted to Parma Wallabies that live within the forest andwho avoided sites with the urine analogue. Thus Pademelons may assess risk bythe decay in odours from potential predators on venturing into open habitatwhereas avoid anyrisk and forage elsewhere in the forest.Blumstein, D.T., Daniel,J.C., Schnell, M.R., Ardron, J.G., Evans, C.S., 2002.
