Atlas of Australian Birds Project Reported White-Faced Herons Feeding on Road Kills (Blakers Et Al AUSTRALIAN 210 ASHTON: Welcome Swallow Breeding in Fairy Martin Nest BIRD WATCHER Atlas of Australian Birds project reported White-faced Herons feeding on road kills (Blakers et al. 1984). One of six White-faced Herons collected at Westernport Bay, Victoria in June 1979 while feeding in pastures had 13 adult flies (Diptera, unspecified) in its stomach (Lowe 1983). Feeding on garbage tips has been recorded in other members of the Ardeidae. Slater (1970) included garbage tips in the habitat of the Pied Heron Ardea picata. He did not indicate the food taken. Dean (1978) listed references to Cattle Egrets Ardeola ibis feeding on refuse tips in Uganda, Seychelles and Morocco. Food was not identified but one observer thought insects were the attraction, not refuse. Cattle Egrets seen by me at a garbage tip at Greenwell Point, New South Wales in 1976 were also feeding on flies which they caught both on the ground and while airborne, snatching them from the air with ease. Again to apply the terms of Hancock & Kushlan (1984), they used Standing Flycatching and Aerial Flycatching methods. I did not see them take any refuse.

W 2717 • Welcome Swallow Breeding in a Fairy Martin Nest Marchant & Fullagar (1983), in an analysis of 1169 nest records for the Welcome Swallow Hirundo neoxena, did not record it breeding in the nest of another species nor have I found reference to this in a limited survey of the literature. An account of the breeding of Welcome Swallows in a broken nest of the Fairy Martin Cecropis ariel follows. A Welcome Swallow was seen at times perched near a road culvert at Aldinga Beach, South Australia (35° 17'S, 138° 27'E) from mid August 1983. Casual inspections of the partly water-filled culvert revealed only about 20 Fairy Martin nests of previous breeding seasons until close inspection became possible on 11 October 1983. Then a broken Fairy Martin nest amongst others at the southern end of the culvert was found to contain four well-feathered young Welcome Swallows which were being fed by the parents. Fairy Martins had been recorded in 1980-82 breeding seasons at these nests and vandalism to them had been noted. The nest being used by the Swallows had lost its neck, the line of attachment to the culvert roof being clearly marked. The bulb of the nest remaining formed a deep saucer, a small section of the rim of which 3.0 x 1.5 em had been repaired by more recently applied mud. The nest was thickly lined with soft material including feathers. On 6 October two of the young fledged and the remainder had done so by 9 October. On 20 October three eggs were found in the same nest to which an VOL. 11 (6) JUNE 1986 SCHULZ: Straw-necked Ibis taking a Western Brown Snake 211 adult Swallow carried a feather. Brooding followed and two young had hatched by 14 November and fledged on 2-3 December. No Fairy Martins nested in the culvert, though present in the area, during this season. When the culvert was inspected during the 1984 breeding season it was found that previous nests had been swept away by water and no other nests built. Reference Marchant, S. & Fullagar, P.J.

Box 125, Aldinga Beach, S.A. 5173 • Straw-necked Ibis Taking a Western Brown Snake In the literature there are scattered accounts of snakes, including venomous species, being captured by large species of wading birds: Australasian Bittern Botaurus poiciloptilus (Hobbs 1979); Intermediate Egret Egretta intermedia (Gill 1963); Black-necked Stork Xenorhynchus asiaticus and Great Egret Egretta alba (Coburn 1977); Sacred Ibis Threskiornis aethiopica (Vestjens 1977). I could find no first-hand accounts of the Straw-necked Ibis Threskiornis spinicollis feeding on snakes, although several references (Frith 1969, Vestjens 1976) mention snakes as part of the bird's diet. Most references to diet refer to its marked preference for grasshoppers and locusts (e.g. Ellis 1958, Carrick 1959, Macdonald 1973, Cowling 1974, Vestjens 1976). Rose (1973) examined the stomach contents of two Straw-necked Ibis and found the remains of a variety of insects, centipedes, a spider and a snail but no traces of any reptiles. On 25 July 1985 a flock of 30 Straw-necked Ibis were observed foraging on grassland dominated by Danthonia caespitosa adjacent to Clarkes Creek, 4.5 km south of Wanganella in south-west New South Wales. One Ibis was suddenly observed holding a snake in its beak, grasping it by the mid section. In order to identify the snake I forced the Ibis to take flight, which resulted in the snake being dropped. The snake, identified as a Western Brown Snake Pseudonaja nucha/is, was found to be in poor condition and subsequently died. This is a common species of snake widespread in inland Australia (Cogger 1983). It weighed 17.5 g and had a total length of 43.5 em.

    116 MOl?llA.N-Thc Migrat'ion 'of Swallows in S.A.. The Migration of Swallows in South Australia. By A. ,M. MORGAN, M.B., Ch.B. Four swallows inhabit South Australia. They are the Welcome-Swallow (Hirundo neoaJena), the Tree Swallow (Hylo­ c7wlidon nigricans caleyi), the Fairy Martin '01' Bottle Swallow (Lagenoplastes ariel), and the White-breasted Swallow (Ohera· mreca lC1tcosternon stonei). None is rconflned to South Aus­ tralia; 'the first theeebave been recorded from every part of the Australian Commonwealth, the fourth from every State except Tasmania, which it does not visit. Authorities differ considerably in their opinions as to the migratory habits of these birds on the Australian Continent. As regards 'I'asmania, all 'are agreed that they are purely migratory, leaving in: the winter, and returning next summer to nest. The flairy mrurtin is' probably only an occasional visitor, since Littler (Birds of Tas~ania) has not seen it. Gould (Handbook of the Birds 'of Australia) says of the welcome swallows-v'Dbe arrival of this bird in the southern portions of Australia is hailed as a welcome indication of the approach of .spring, and .is associated with precisely the same ideas as those popularly entertained respecting our own pretty swallow 'in Europe. The two species are, in fact, beautiful representatives of each other, and, assimilate ... in their migratory movements." Quoting Caley, he says further, "the earliest perjod of the year that I noticed the 'appearance of swallows. was July 12th, 1803, when 1 saw two . The latest period I 'observed them was 30th Ma~, 1806, when It number of them were flying high in the air." Gould also says, " ,u.

  • Innovative Foraging by the House Sparrow Passer Domesticus
    46 AUSTRALIAN FIELD ORNITHOLOGY 2005, 22, 46--47 Innovative Foraging by the House Sparrow Passer domesticus NEIL SHELLEY 16 Birdrock Avenue, Mount Martha, Victoria 3934 (Email: [email protected]) Summary This note describes an incidental observation of House Sparrows Passer domesticus foraging for insects trapped within the engine bay of motor vehicles in south-eastern Australia. Introduction The House Sparrow Passer domesticus is commensal with man and its global range has increased significantly recently, closely following human settlement on most continents and many islands (Long 1981, Cramp 1994). It is native to Eurasia and northern Africa (Cramp 1994) and was introduced to Australia in the mid 19th century (Biakers et al. 1984, Schodde & Tidemann 1997, Pizzey & Knight 1999). It is now common in cities and towns throughout eastern Australia (Biakers et al. 1984, Schodde & Tidemann 1997, Pizzey & Knight 1999, Barrett et al. 2003), particularly in association with human habitation (Schodde & Tidemann 1997), but is decreasing nationally (Barrett et al. 2003). Observation On 13 January 2003 at c. 1745 h Eastern Summer Time, a small group of House Sparrows was observed foraging in the street outside a restaurant in Port Fairy, on the south-western coast of Victoria (38°23' S, 142°14' E). Several motor vehicles were angle-parked in the street, nose to the kerb, adjacent to the restaurant. The restaurant had a few tables and chairs on the footpath for outside dining. The Sparrows appeared to be foraging only for food scraps, when one of them entered the front of a parked vehicle and emerged shortly after with an insect, which it then consumed.

  • The Evolution of Nest Construction in Swallows (Hirundinidae) Is Associated with the Decrease of Clutch Size
    © Biologiezentrum Linz/Austria; download unter www.biologiezentrum.at Linzer biol. Beitr. 38/1 711-716 21.7.2006 The evolution of nest construction in swallows (Hirundinidae) is associated with the decrease of clutch size P. HENEBERG A b s t r a c t : Variability of the nest construction in swallows (Hirundinidae) is more diverse than in other families of oscine birds. I compared the nest-building behaviour with pooled data of clutch size and overall hatching success for 20 species of swallows. The clutch size was significantly higher in temperate cavity-adopting swallow species than in species using other nesting modes including species breeding in evolutionarily advanced mud nests (P<0.05) except of the burrow-excavating Bank Swallow. Decrease of the clutch size during the evolution of nest construction is not compensated by the increase of the overall hatching success. K e y w o r d s : Hirundinidae, nest construction, clutch size, evolution Birds use distinct methods to avoid nest-predation: active nest defence, nest camouflage and concealment or sheltered nesting. While large and powerful species prefer active nest-defence, swallows and martins usually prefer construction of sheltered nests (LLOYD 2004). The nests of swallows vary from natural cavities in trees and rocks, to self-exca- vated burrows to mud retorts and cups attached to vertical faces. Much attention has been devoted to the importance of controlling for phylogeny in com- parative tests (HARVEY & PAGEL 1991), including molecular phylogenetic studies of swallows (WINKLER & SHELDON 1993). Interactions between the nest-construction va- riability and the clutch size, however, had been ignored.

Now in its 6th year, the Aussie Backyard Bird Count is occurring between 21st till the 27th of October and is facilitated by Birdlife Australia. Over the course the week participants are encouraged to observe birds around them for 20 minutes using the Aussie Backyard Bird Count app. What is cool is you don’t have to stay in your backyard, you can visit your local pack, nature reserve or head to the beach. Who can’t find 20 minutes, to stop and observe bird occurring in your local area? Who is BirdLife Australia? Birdlife Australia is the largest, independent, non-profit bird conservation organisation in Australia. They run the Backyard Bird Count each year to obtain valuable data on bird communities throughout Australia. The trends extrapolated from this data can be used to get a glimpse into the changes bird populations are undergoing, and subsequently the environment, as Australia’s Unique changes in populations are a reflection of changes in the environment. The count is Birds held in October each year to capture migratory birds which are returning to Australia from the northern hemisphere for nesting, breeding and flocking. Many of these migratory birds are water birds that flock to our coasts where most human populations are situated, making it an ideal time of year for counts. Backyard Bird Count Results 2018 In 2018, 76,918 people in Australia counted 2,751,113 birds over the 7-days period.

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.
