Host Alarm Calls Attract the Unwanted Attention of the Brood Parasitic
www.nature.com/scientificreports OPEN Host alarm calls attract the unwanted attention of the brood parasitic common cuckoo Attila Marton 1,2*, Attila Fülöp 2,3, Katalin Ozogány1, Csaba Moskát 4,5 & Miklós Bán 1,3,5 It is well known that avian brood parasites lay their eggs in the nests of other bird species, called hosts. It remains less clear, however, just how parasites are able to recognize their hosts and identify the exact location of the appropriate nests to lay their eggs in. While previous studies attributed high importance to visual signals in fnding the hosts’ nests (e.g. nest building activity or the distance and direct sight of the nest from vantage points used by the brood parasites), the role of host acoustic signals during the nest searching stage has been largely neglected. We present experimental evidence that both female and male common cuckoos Cuculus canorus pay attention to their host’s, the great reed warbler’s Acrocephalus arundinaceus alarm calls, relative to the calls of an unparasitized species used as controls. Parallel to this, we found no diference between the visibility of parasitized and unparasitized nests during drone fights, but great reed warblers that alarmed more frequently experienced higher rates of parasitism. We conclude that alarm calls might be advantageous for the hosts when used against enemies or for alerting conspecifcs, but can act in a detrimental manner by providing important nest location cues for eavesdropping brood parasites. Our results suggest that host alarm calls may constitute a suitable trait on which cuckoo nestlings can imprint on to recognize their primary host species later in life. -

The present geological period has more species than any other, yet the current rate of extinction of species is greater now than at any time in the past. Ecosystems and communities are being degraded and destroyed, and species are being driven to extinction. The species that persist are losing genetic variation as the number of individuals in populations shrinks, unique populations and subspecies are destroyed, and remaining populations become increasingly isolated from one another. The cause of this loss of biological diversity at all levels is the range of human activity that alters and destroys natural habitats to suit human needs.” (Primack, 2002). CapeNature launched its State of Biodiversity Programme (SoBP) to assess and monitor the state of biodiversity in the Western Cape in 1999. This programme delivered its first report in 2002 and these reports are updated every five years. The current report (2007) reports on the changes to the state of vertebrate biodiversity and land under conservation usage. -
Status and Occurrence of White Wagtail (Motacilla Alba) in British Columbia
Status and Occurrence of White Wagtail (Motacilla alba) in British Columbia. By Rick Toochin and Don Cecile. Introduction and Distribution The White Wagtail (Motacilla alba) is a small passerine species that is found throughout the Old World: breeding from the southeastern tip of Greenland, and Iceland; from Great Britain, south to Morocco, across all of Europe; throughout western Russia, all of Turkey, Iran, Afghanistan, along the Himalayas east into southern China, Mongolia, all of eastern Russia, and into western coastal areas of Alaska (Alstrom and Mild 2003). The White Wagtail winters from Great Britain, south throughout western Europe from Germany to Spain, east through Italy, Greece, into Turkey and the Middle East, south into the northern countries of Africa, east to Saudi Arabia, throughout Iraq, Iran, into India, east throughout south east Asia north through southern China, the northern Philippines, Taiwan and Japan (Alstrom and Mild 2003). There are 9 recognized subspecies found throughout the range of the White Wagtail with only 3 having been recorded in North America (Alstrom and Mild 2003). The nominate subspecies of White Wagtail (Motacilla alba alba) has occurred accidentally along the east coast of North America (Hamilton et al. 2007, Dunn and Alderfer 2011). In western North America, the White Wagtails that occur are from the subspecies that make up the (Motacilla alba ocularis/lugens) complex (Sibley 2000, Dunn and Alderfer 2011). These two subspecies were once separate species with one called White Wagtail (Motacilla alba ocularis) and the other called Black-backed Wagtail (Motacilla alba lugens) (Alstrom and Mild 2003). In 2005, the AOU officially lumped Black- backed Wagtail back with White Wagtail and now the Black-backed Wagtail is considered a subspecies of the White Wagtail (Banks et al. -

American Pipit Anthus Rubescens
American Pipit Anthus rubescens Folk Name: Water Pipit, Titlark, Skylark, Brownlark Status: Migrant, Winter Visitor Abundance: Uncommon to Common Habitat: Bare-ground, short-grass fields, pastures, lawns, mudflats The American Pipit was once called the Water Pipit and the Titlark. For a time, it was called the Skylark, similar to the Eurasian Skylark—a famous soaring songbird. However, the two are not closely related. “What of the word ‘lark,’ as meaning a frolic? The Anglo- Saxon word ‘lark,’ meaning play. So a sky lark is the bird that frolics, or plays, or rejoices, or ‘larks,’ in the air or s k y.” — The People’s Press, Winston-Salem, March 6, 1857 The American Pipit is a fairly nondescript winter In the late 1870s, Leverett Loomis considered the visitor usually encountered in small loose flocks foraging “Brownlark” as an “abundant” winter resident in Chester on the ground in large open areas of very short grass, County, SC. In North Carolina in 1939, C. S. Brimley mudflats, pasture, or dirt fields.

South Africa Mega Birding Tour I 6th to 30th January 2018 (25 days) Trip Report Aardvark by Mike Bacon Trip report compiled by Tour Leader: Wayne Jones Rockjumper Birding Tours View more tours to South Africa Trip Report – RBT South Africa - Mega I 2018 2 Tour Summary The beauty of South Africa lies in its richness of habitats, from the coastal forests in the east, through subalpine mountain ranges and the arid Karoo to fynbos in the south. We explored all of these and more during our 25-day adventure across the country. Highlights were many and included Orange River Francolin, thousands of Cape Gannets, multiple Secretarybirds, stunning Knysna Turaco, Ground Woodpecker, Botha’s Lark, Bush Blackcap, Cape Parrot, Aardvark, Aardwolf, Caracal, Oribi and Giant Bullfrog, along with spectacular scenery, great food and excellent accommodation throughout. ___________________________________________________________________________________ Despite havoc-wreaking weather that delayed flights on the other side of the world, everyone managed to arrive (just!) in South Africa for the start of our keenly-awaited tour. We began our 25-day cross-country exploration with a drive along Zaagkuildrift Road. This unassuming stretch of dirt road is well-known in local birding circles and can offer up a wide range of species thanks to its variety of habitats – which include open grassland, acacia woodland, wetlands and a seasonal floodplain.

Summary 2. Study area 3. Avian fauna and conservation status of threatened bird species 4. Habitat analysis 5. Ecological assessment and community education 6. Outputs 7. Main references 8. Acknowledgements 1. Summary Laojunshan Nature Reserve is located at Yibin city, Sichuan province, south China. It belongs to eastern part of Liangshan mountains and is among the twenty-five hotspots of global biodiversity conservation. The local virgin alpine subtropical deciduous forests are abundant, which are actually rare at the same latitudes and harbor a tremendous diversity of plant and animal species. It is listed as a Global 200 ecoregion (WWF), an Important Bird Area (No. CN205), and an Endemic Bird Area (No. D14) (Stattersfield, et al . 1998). However, as a nature reserve newly built in 1999, it is only county-level and has no financial support from the central government. Especially, it is quite lack of scientific research, for example, the avifauna still remains unexplored except for some observations from bird watchers. Furthermore, the local community is extremely poor and facing modern development pressures, unmanaged human activities might seriously disturb the local ecosystem. We conducted our project from April to June 2007, funded by Conservation Leadership Programme. Two fieldwork strategies were used: “En bloc-Assessment” to produce an avifauna census and ecological assessments; "Special Survey" to assess the conservation status of some threatened endemic bird species. -

Nepal is rich in bird diversity and recorded 871 bird species. Our study aimed to update bird diversity of Dhorpatan Hunting Reserve (DHR) of Nepal which is an Important Birds Area (IBA) out of 27 IBAs of Nepal. One hundred forty nine species of birds were recorded in DHR; out of them Catreus wallichii was globally threatened bird which has faced different anthropogenic problem. Twelve species of birds were included in CITIES Appendices and 3 species were nationally threatened. Most of the species of order Passeriformis were recorded. Only one species of order Upupiformes i.e. Upupa epops was recorded dur- ing the study.

>> SPLITS, LUMPS AND SHUFFLES Splits, lumps and shuffles Thomas S. Schulenberg This series focuses on recent taxonomic proposals – descriptions of new taxa, splits, lumps or reorganisations – that are likely to be of greatest interest to birders. This latest instalment includes: the possible lumps of Scale-breasted Woodpecker and South Georgia Pipit; a split in Red-billed Woodcreeper; a split in Highland Elaenia, and yet another possible lump in White-crested Elaenia; and a too-early-to-call-for-a-split-but-keep-an-eye-on-it study of Correndera Pipit. Sayonara, Scale-breasted There has been some grumbling over the years that a subspecies of Waved (amacurensis, of Woodpecker? northeastern Venezuela) perhaps belongs instead cale-breasted Woodpecker Celeus with Scale-breasted (Short 1982), and reports that grammicus and Waved Woodpecker C. not only were their vocalisations indistinguishable S undatus are two similar species that replace (Ridgely & Greenfield 2001), but even that each each other geographically, occupying respectively responded to playback of calls of the other (Restall the western and eastern portions of Amazonia. et al. 2006).

The absence of diagnostic vocal, plumage, or genetic differences between the two all seems to lead to the conclusion that there is one fewer species of woodpecker in the world. -
