There is a growing recognition of the need to integrate non-trophic interactions into ecological networks for a better understanding of whole-community organization. To achieve this, the first step is to build networks of individual non- trophic interactions. In this study, we analyzed a network of interdependencies among bird species that participated in heterospecific foraging associations (flocks) in an evergreen forest site in the Western Ghats, India. We found the flock network to contain a small core of highly important species that other species are strongly dependent on, a pattern seen in many other biological networks. Further, we found that structural importance of species in the network was strongly correlated to functional importance of species at the individual flock level. Finally, comparisons with flock networks from other Asian forests showed that the same taxonomic groups were important in general, suggesting that species importance was an intrinsic trait and not dependent on local ecological conditions. Hence, given a list of species in an area, it may be possible to predict which ones are likely to be important. -
Vietnam Southern and Central Specialties 15Th to 29Th February 2020 (15 Days) Trip Report
Vietnam Southern and Central Specialties 15th to 29th February 2020 (15 days) Trip Report Siamese Fireback by Simon Tan Trip report compiled by Tour Leader: Glen Valentine Trip Report – RBL Vietnam – Southern & Central Specialties 2020 2 Tour Summary Orange-breasted Trogon by Simon Tan We kicked off our 2020 Southern and Central Vietnam tour in the city of Hue, teeming with history and cultural significance and some wonderful restaurants, making it the perfect place to spend a few pre-tour days ambling around the city and its surrounds. Beginning our long journey south towards the hill forests surrounding the village of Mang Den, our first scheduled birding stop of the day produced the wanted target species in the form of White-faced Plover (a very distinctive, extremely localized, rare and often- split subspecies of Kentish Plover) along the beach adjacent to Bach Ma National Park. In the same area, we added our first of several Light-vented Bulbuls, a female Stejneger’s Stonechat and flocks of fly-over Grey-capped Greenfinches. Continuing west and then southwards, crossing over the Lo Xo Pass after a quick lunch-stop we had an hour or so to find the scarce and exceedingly range-restricted near-endemic Black-crowned Barwing. This good-looking and charismatic species was only discovered as recently as 1996 and is still only known from a tiny area in south-central Vietnam and southern Laos. We arrived in fine weather and were soon admiring several pairs and family groups of Black-collared Starling, as well as Scarlet Minivet, Streaked Spiderhunter, Black Bulbul, a wonderful perched Necklaced Barbet, a pair of Large Woodshrike and then finally, after a fair amount of searching in the now-degraded road- edge habitat, a glorious pair of Black-crowned Necklaced Barbet by Glen Valentine Rockjumper Birding Tours View more tours to Vietnam Trip Report – RBL Vietnam – Southern & Central Specialties 2020 3 Barwings. -

Field Guides Tour Report Taiwan 2020 Feb 1, 2020 to Feb 12, 2020 Phil Gregory & local guide Arco Huang For our tour description, itinerary, past triplists, dates, fees, and more, please VISIT OUR TOUR PAGE. This gorgeous male Swinhoe's Pheasant was one of the birds of the trip! We found a pair of these lovely endemic pheasants at Dasyueshan. Photo by guide Phil Gregory. This was a first run for the newly reactivated Taiwan tour (which we last ran in 2006), with a new local organizer who proved very good and enthusiastic, and knew the best local sites to visit. The weather was remarkably kind to us and we had no significant daytime rain, somewhat to my surprise, whilst temperatures were pretty reasonable even in the mountains- though it was cold at night at Dasyueshan where the unheated hotel was a bit of a shock, but in a great birding spot, so overall it was bearable. Fog on the heights of Hohuanshan was a shame but at least the mid and lower levels stayed clear. Otherwise the lowland sites were all good despite it being very windy at Hengchun in the far south. Arco and I decided to use a varied assortment of local eating places with primarily local menus, and much to my amazement I found myself enjoying noodle dishes. The food was a highlight in fact, as it was varied, often delicious and best of all served quickly whilst being both hot and fresh. A nice adjunct to the trip, and avoided losing lots of time with elaborate meals. -

We constructed a species checklist for all herpetofauna of this area based on a short-term field survey, a comprehensive literature review, museum specimens, and observations made by field herpetologists. Based on 200 × 10 m belt transects, we surveyed herpetofauna both during day and night time, in 10 different types of habitats. The species checklist we compiled comprised 44 species of reptiles (including three nationally threatened, one globally threatened, and eight endemic species) and 15 species of amphibians (including one nationally threatened and three endemic species). Based on published literature, museum specimens, expert opinions, and current field survey, we documented 85 species of herpetofauna in this area. Of this entire list, we were unable to record the presence of 25 species through our field survey. Our field survey documented 18 species that were not previously reported from Jaffna Peninsula. Our study revealed that inland water bodies, cultivated lands, home gardens, and coastal beaches are of high impor- tance for native herpetofauna of Jaffna peninsula. Many human disturbances, such as habitat alterations, vengeful killing, consumption overexploitation, and road mortality are the key threats encountered by herpetofauna in Jaffna. -
Disaggregation of Bird Families Listed on Cms Appendix Ii
Convention on the Conservation of Migratory Species of Wild Animals 2nd Meeting of the Sessional Committee of the CMS Scientific Council (ScC-SC2) Bonn, Germany, 10 – 14 July 2017 UNEP/CMS/ScC-SC2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II (Prepared by the Appointed Councillors for Birds) Summary: The first meeting of the Sessional Committee of the Scientific Council identified the adoption of a new standard reference for avian taxonomy as an opportunity to disaggregate the higher-level taxa listed on Appendix II and to identify those that are considered to be migratory species and that have an unfavourable conservation status. The current paper presents an initial analysis of the higher-level disaggregation using the Handbook of the Birds of the World/BirdLife International Illustrated Checklist of the Birds of the World Volumes 1 and 2 taxonomy, and identifies the challenges in completing the analysis to identify all of the migratory species and the corresponding Range States. The document has been prepared by the COP Appointed Scientific Councilors for Birds. This is a supplementary paper to COP document UNEP/CMS/COP12/Doc.25.3 on Taxonomy and Nomenclature UNEP/CMS/ScC-Sc2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II 1. Through Resolution 11.19, the Conference of Parties adopted as the standard reference for bird taxonomy and nomenclature for Non-Passerine species the Handbook of the Birds of the World/BirdLife International Illustrated Checklist of the Birds of the World, Volume 1: Non-Passerines, by Josep del Hoyo and Nigel J. Collar (2014); 2. -

Sichuan, China
Tropical Birding: Sichuan (China). Custom Tour Report A Tropical Birding custom tour SICHUAN, CHINA : (Including the Southern Shans Pre-tour Extension) WHITE-THROATED TIT One of 5 endemic tits recorded on the tour. 21 May – 12 June, 2010 Tour Leader: Sam Woods All photos were taken by Sam Woods/Tropical Birding on this tour, except one photo. www.tropicalbirding.com [email protected] 1-409-515-0514 Tropical Birding: Sichuan (China). Custom Trip Report The Central Chinese province of Sichuan provided some notable challenges this year: still recovering from the catastrophic “Wenchuan 5.12” earthquake of 2008, the area is undergoing massive reconstruction. All very positive for the future of this scenically extraordinary Chinese region, but often a headache for tour arrangements, due to last minute traffic controls leading us to regularly rethink our itinerary in the Wolong area in particular, that was not far from the epicenter of that massive quake. Even in areas seemingly unaffected by the quake, huge road construction projects created similar challenges to achieving our original planned itinerary. However, in spite of regular shuffling and rethinking, the itinerary went ahead pretty much as planned with ALL sites visited. Other challenges came this year in the form of heavy regular rains that plagued us at Wawu Shan and low cloud that limited visibility during our time around the breathtaking Balang Mountain in the Wolong region. With some careful trickery, sneaking our way through week-long road blocks under cover of darkness, birding through thick and thin (mist, cloud and rains) we fought against all such challenges and came out on top. -
Avifaunal Diversity of Bibhutibhushan Wildlife Sanctuary, West Bengal, India
Available online at www.worldscientificnews.com WSN 71 (2017) 150-167 EISSN 2392-2192 Avifaunal Diversity of Bibhutibhushan Wildlife Sanctuary, West Bengal, India Shiladitya Mukhopadhyay1,* and Subhendu Mazumdar2 1Post Graduate Department of Zoology, Barasat Government College, North 24 Parganas, India 2Department of Zoology, Shibpur Dinobundhoo Institution (College), Shibpur, Howrah, India *E-mail address: [email protected] ABSTRACT Birds are found in a variety of habitats, performing various functions. They are highly sensitive to even minor perturbation in ecosystems. Documentation of avian assemblages in different ecosystems is, therefore, becoming increasingly important from environmental monitoring perspective. In absence of comprehensive account of birds of Bibhutibhushan Wildlife Sanctuary, West Bengal, India, we made an attempt to document the birds thriving in this protected area. A total of 102 species of birds belonging to 13 orders and 46 families were recorded during the study period (June 2013 – May 2016). Maximum number of species belong to the order Passeriformes (49 species) and minimum under order Anseriformes (1 species). Among the total bird species, 83 species (81.37%) were resident, 15 species (14.71%) were winter visitor, three species (2.94%) were summer visitor and one species (0.98%) was passage migrant. We noted 38 species of birds (including 36 residents and two summer visitors) to breed within the sanctuary. Analysis of feeding guild data revealed that 46.08% were insectivore, 22.55% were carnivore, 15.69% were omnivore, 6.86% were granivore, 5.88% were frugivore, 1.96% were nectarivore and 0.98% were herbivore. Grey-headed Fish Eagle (Icthyophaga ichthyaetus) and Red- breasted Parakeet (Psittacula alexandri) are two Near Threatened (NT) species designated by IUCN. -
