  • Eastern Rosella (Platycercus Eximius)
    Eastern rosella (Platycercus eximius) Class: Aves Order: Psittaciformes Family: Psittaculidae Characteristics: The Eastern rosella averages 30 cm (12 in) in length and 99gm (3.5oz) in weight. With a red head and white cheeks, the upper breast is red and the lower breast is yellow fading to pale green over the abdomen. The feathers of the back and shoulders are black, and have yellowish or greenish margins giving rise to a scalloped appearance that varies slightly between three subspecies and the sexes. The wings and lateral tail feathers are bluish while the tail is dark green. Range & Habitat: Behavior: Like most parrots, Eastern rosellas are cavity nesters, generally Eastern Australia down to nesting high in older large trees in forested areas. They enjoy bathing in Tasmania in wooded country, puddles of water in the wild and in captivity and frequently scratch their open forests, woodlands and heads with the foot behind the wing. Typical behavior also includes an parks. Nests in tree cavities, undulating flight, strutting by the male, and tail wagging during various stumps or posts. displays such as courting, and a high-pitched whistle consisting of sharp notes repeated rapidly in quick succession. Reproduction: Breeding season is influenced by rain and location. Courting male bows while sounding out mating call followed by mutual feeding and then mating. Female alone incubates eggs while male bring food. 2-9 eggs will hatch in 18 - 20 days. Hatchlings are ready to leave the nest in about 5 weeks but may stay with their parents for several months unless there is another mating.

    Chestnut-backed Button-quail in the north was a bonus, showing brilliantly for a long time – unheard of for this family (Andy Jensen) WESTERN AUSTRALIA 5/10 – 27 SEPTEMBER 2017 LEADER: ANDY JENSEN ASSISTANT: STUART PICKERING ! ! 1 BirdQuest Tour Report: Western Australia (including Christmas Island) 2017 www.birdquest-tours.com Western Shrike-tit was one of the many highlights in the southwest (Andy Jensen) Western Australia, if it were a country, would be the 10th largest in the world! The BirdQuest Western Australia (including Christmas Island) 2017 tour offered an unrivalled opportunity to cover a large portion of this area, as well as the offshore territory of Christmas Island (located closer to Indonesia than mainland Australia). Western Australia is a highly diverse region with a range of habitats. It has been shaped by the isolation caused by the surrounding deserts. This isolation has resulted in a richly diverse fauna, with a high degree of endemism. A must visit for any birder. This tour covered a wide range of the habitats Western Australia has to offer as is possible in three weeks, including the temperate Karri and Wandoo woodlands and mallee of the southwest, the coastal heathlands of the southcoast, dry scrub and extensive uncleared woodlands of the goldfields, coastal plains and mangroves around Broome, and the red-earth savannah habitats and tropical woodland of the Kimberley. The climate varied dramatically Conditions ranged from minus 1c in the Sterling Ranges where we were scraping ice off the windscreen, to nearly 40c in the Kimberley, where it was dust needing to be removed from the windscreen! We were fortunate with the weather – aside from a few minutes of drizzle as we staked out one of the skulkers in the Sterling Ranges, it remained dry the whole time.

My goal was to get some first-hand impressions of two very threatened parrots: the Red-fronted Macaw (Ara rubrogenys) and the Blue-throated Macaw (Ara SceneScene glaucogularis). We have published very little about the Red-fronted Macaw in PsittaScene,a species that is globally Endangered, and lives in the foothills of the Andes in central Bolivia.
