Distribution, Natural History and Conservation Status of Two
Bird Conservation International (2008) 18:331–348. ª BirdLife International 2008 doi:10.1017/S0959270908007491 Printed in the United Kingdom Distribution, natural history and conservation status of two endemics of the Bolivian Yungas, Bolivian Recurvebill Simoxenops striatus and Yungas Antwren Myrmotherula grisea SEBASTIAN K. HERZOG, A. BENNETT HENNESSEY, MICHAEL KESSLER and VI´CTOR H. GARCI´A-SOLI´Z Summary Since their description in the first half of the 20th century by M. A. Carriker, Bolivian Recurvebill Simoxenops striatus and Yungas Antwren Myrmotherula grisea have been regarded as extremely poorly known endemics of the Bolivian Yungas and adjacent humid foothill forests. They are considered ‘Vulnerable’ under the IUCN criteria of small population, predicted population decline (criterion C2a) and, in the case of Bolivian Recurvebill, small extent of occurrence (criteria B1a+b). Here we summarise the information published to date and present extensive new data on the distribution (including the first records for extreme southeast Peru), natural history, population size and conservation status of both species based on field work in the Bolivian Andes over the past 12 years. Both species primarily inhabit the understorey of primary and mid-aged to older regenerating forest and regularly join mixed-species foraging flocks of insectivorous birds. Bolivian Recurvebill has a strong preference for Guadua bamboo, but it is not an obligate bamboo specialist and persists at often much lower densities in forests without Guadua. Yungas Antwren seems to have a preference for dense, structurally complex under- storey, often with Chusquea bamboo. Both species are distributed much more continuously at altitudes of mostly 600–1,500 m, occupy a greater variety of forest types (wet, humid, semi- deciduous forest) and have a much greater population size than previously thought. -
Ultimate Bolivia Tour Report 2019
Titicaca Flightless Grebe. Swimming in what exactly? Not the reed-fringed azure lake, that’s for sure (Eustace Barnes) BOLIVIA 8 – 29 SEPTEMBER / 4 OCTOBER 2019 LEADER: EUSTACE BARNES Bolivia, indeed, THE land of parrots as no other, but Cotingas as well and an astonishing variety of those much-loved subfusc and generally elusive denizens of complex uneven surfaces. Over 700 on this tour now! 1 BirdQuest Tour Report: Ultimate Bolivia 2019 www.birdquest-tours.com Blue-throated Macaws hoping we would clear off and leave them alone (Eustace Barnes) Hopefully, now we hear of colourful endemic macaws, raucous prolific birdlife and innumerable elusive endemic denizens of verdant bromeliad festooned cloud-forests, vast expanses of rainforest, endless marshlands and Chaco woodlands, each ringing to the chorus of a diverse endemic avifauna instead of bleak, freezing landscapes occupied by impoverished unhappy peasants. 2 BirdQuest Tour Report: Ultimate Bolivia 2019 www.birdquest-tours.com That is the flowery prose, but Bolivia IS that great destination. The tour is no longer a series of endless dusty journeys punctuated with miserable truck-stop hotels where you are presented with greasy deep-fried chicken and a sticky pile of glutinous rice every day. The roads are generally good, the hotels are either good or at least characterful (in a good way) and the food rather better than you might find in the UK. The latter perhaps not saying very much.

That said, Bolivia has work to do too, as its association with that hapless loser, Che Guevara, corruption, dust and drug smuggling still leaves the country struggling to sell itself. -
Bolivia: the Andes and Chaco Lowlands
BOLIVIA: THE ANDES AND CHACO LOWLANDS TRIP REPORT OCTOBER/NOVEMBER 2017 By Eduardo Ormaeche Blue-throated Macaw www.birdingecotours.com [email protected] 2 | T R I P R E P O R T Bolivia, October/November 2017 Bolivia is probably one of the most exciting countries of South America, although one of the less-visited countries by birders due to the remoteness of some birding sites. But with a good birding itinerary and adequate ground logistics it is easy to enjoy the birding and admire the outstanding scenery of this wild country. During our 19-day itinerary we managed to record a list of 505 species, including most of the country and regional endemics expected for this tour. With a list of 22 species of parrots, this is one of the best countries in South America for Psittacidae with species like Blue-throated Macaw and Red-fronted Macaw, both Bolivian endemics. Other interesting species included the flightless Titicaca Grebe, Bolivian Blackbird, Bolivian Earthcreeper, Unicolored Thrush, Red-legged Seriema, Red-faced Guan, Dot-fronted Woodpecker, Olive-crowned Crescentchest, Black-hooded Sunbeam, Giant Hummingbird, White-eared Solitaire, Striated Antthrush, Toco Toucan, Greater Rhea, Brown Tinamou, and Cochabamba Mountain Finch, to name just a few. We started our birding holiday as soon as we arrived at the Viru Viru International Airport in Santa Cruz de la Sierra, birding the grassland habitats around the terminal. Despite the time of the day the airport grasslands provided us with an excellent introduction to Bolivian birds, including Red-winged Tinamou, White-bellied Nothura, Campo Flicker, Chopi Blackbird, Chotoy Spinetail, White Woodpecker, and even Greater Rhea, all during our first afternoon. -

Monitoring Ecosystems and Biodiversity at a Continental Scale—A Proposal for South America
Monitoring Ecosystems and Biodiversity at a Continental Scale—A Proposal for South America Dr. Xavier Silva, Director, IDB-TNC Ecoregional Project, South America. Teacher and Lecturer, San Francisco de Quito University. Board Member, OÏKOS Foundation Abstract—A monitoring system plan is being developed in South America to assess critically endangered ecoregions. The system will be based on a previous ecosystem and biodiversity inventory developed through a large gap analysis program in five South American ecoregions. The monitoring system will include three main elements: (1) Landscape Ecology: vegetation cover, fragmentation and deforestation, infrastruc- ture (road, dams, pipelines); (2) Biological guidelines: species richness, endemism, endangered species and species of a particular interest; and (3) Conservation Policy and Socio-Economic guidelines: national protected areas systems, conservation policies, human population on important areas, main economic activities and other. Such a sys- tem is an important need for governments and private organizations in South America, especially to detect critical sites and socio-political issues before the environmental problems become too large. Introduction and Background Among the results, 6,473 species of flora and fauna have been analyzed (each one with a map indicating it’s Environmental surveillance at a continental scale is potential geographic distribution), and over 6,500 the- an important conservation requirement in vast territo- matic maps have been produced, indicating vegetation ries, such as in South America, where large and diverse types, centers of high diversity and endemism, current ecoregions are being altered by a number of unsustainable and potential threats, forest fragmentation, infrastructure, location of protected areas, and basic socio-economical development practices (Busch and Trexler 2003, World information. -
Guyana and Suriname, 2011
Trip Report Guyana and Suriname - February/March 2011 Report by Sjef Öllers Introduction The main aim of this holiday was to get an introduction to the wildlife of the Guyanas with, as always, mammals and birds being the main focus. The birding far exceeded my expectations: sightings of purple-breasted and pompadour cotinga, Guianan red-cotinga, capuchinbird, Guianan cock-of-the-rock, purple-throated and crimson fruitcrow, scarlet ibis and two! harpy eagles were unforgettable. And then I have not yet mentioned white- winged potoo, slaty-backed forest-falcon, hoatzins almost at touching distance, blood- coloured woodpecker and arrowhead piculet (currently Surinam’s only endemic). Mammal sightings were mildly disappointing, partly because the lodge where we wanted to focus on mammals was such a mess. Nevertheless, it was fantastic to see all eight possible monkey species (and see them well). Another highlight was kinkaJou on several night walks. Seeing the manatees in Georgetown Botanical Gardens, despite being very tame, was great too. A Jaguar was seen only for a few seconds when it crossed the road in Iwokrama. Rufous Crab Hawk Harpy Eagle Travel Arrangements and Some Notes on Independent Travel In Suriname both accommodations (Hotel De Plantage near TamanredJo and Residence Inn in Paramaribo) were booked directly. Both have a good website: http://www.deplantagecommewiJne.com/ and http://www.resinn.com/. In Guyana we made the bookings through Wilderness Explorers. We were late with booking the tour (only a few weeks in advance) and it required some effort to get everything booked. In the end, however, Wilderness Explorers managed to get a program booked that was almost exactly what we asked (February is high season and usually the busiest month of the year and indeed the accommodations in Surama, Karanambu and Iwokrama River Lodge were fully booked for several nights. -
Some New Information on the Distribution of Venezuelan Birds
Some new information on the distribution of Venezuelan birds Peter Boesman Como resultado de la observación de aves en el campo durante los ultimos 10 años, se presenta un resumen de nuevos datos de distribución de aves en Venezuela. Los datos están organizados por area (20 en total), la mayoria de las areas son poco conocidas. Las observaciones de mayor importancia se detallan en ‘appendix 1’. En Falcón, la Serranía de San Luis tiene muchas más especies tipicas de las alturas sub-tropicales de la Cordillera de la Costa que previamente conocido, las serranias en el noreste de Falcón, de alturas bajas, tienen una avifauna abundante de especies de selva tropical, y areas de agua dulce en esta misma parte de Falcón y el norte de Carabobo son un refugio para muchas especies acuaticas poco conocidas. Los Andes en Lara y Trujillo no han sido estudiados tan profundamente como en Mérida, y por consecuencia se han descubierto importantes extensiones en la distribución de varias especies. En Mérida, se documenta indicaciones de una ruta migratoria muy importante a través del Valle del Río Santo Domingo. Las alturas bajas del Parque Nacional Tamá en Táchira (en el valle de los ríos Frio y Negro) y las areas adjacentes en Apure merecen mayor investigación en vista de algunas observaciones sorprendentes. Igualmente, los descubrimientos en islas del Río Orinoco fueron inesperados. La selva del Río Caura en el norte de Bolívar alberga especies previamente conocidas solamente del estado de Amazonas, y la región del Río Grande en el noreste de Bolívar tiene una avifauna tipicamente Guyanesa. -

Biodiversity Conservation at the Landscape Scale a Program of the Wildlife Conservation Society Supported by the USAID/Global Conservation Program
Biodiversity Conservation at the Landscape Scale A Program of the Wildlife Conservation Society Supported by the USAID/Global Conservation Program Greater Madidi Landscape Conservation Area Implementation Plan October 2006 – September 2007 Living Landscapes Program- Bolivia/Madidi Wildlife Conservation Society 30 September 2006 USAID EGAT/NRM/Biodiversity Leader with Associates Cooperative Agreement Award LAG-A-00-99-00047-00 Biodiversity Conservation at the Landscape Scale A Program of the Wildlife Conservation Society Supported by the USAID/EGAT Global Conservation Program Greater Madidi Landscape Conservation Area Implementation Plan FY2007 October 2006 – September 2007 Program Goal To ensure conservation of biological diversity in regions of global biodiversity importance, using a species-based landscape approach. The Wildlife Conservation Society believes that protected areas must remain at the core of all nations’ biodiversity conservation plans. These areas typically contain a higher diversity and abundance of plants and animals than landscapes managed primarily for economic use. Yet, parks and reserves are always embedded in larger, human-dominated landscapes and are seldom sacrosanct. Regardless of how large or small a protected area may be, the plants and animals it contains are often threatened either directly or indirectly by human resource use activities. Management of parks and reserves cannot, therefore, occur in isolation from the surrounding human-dominated landscape, but must take into account where and how human activities conflict with biodiversity conservation, and where conservation adversely impacts human welfare. As human populations continue to expand over the next 50 years, the incentive for over- exploiting natural resources within and outside of protected areas will likely increase and the need for biodiversity conservation tools that address human-wildlife conflict will become even more important. -
Roosting Solitary Tinamous [Tinamus Solitarius (Vieillot, 1819)] Pr

Centro IDEAL. Pilar, Ñeembucú, Paraguai IIFAUNA Paraguay. Encarnación, Itapúa, Paraguai IIIBirdquest Ltd. Clitheroe, Lancashire, Reino Unido Abstract: Observations of defensive behaviours in two species of tinamous are described. Use of the subcaudal feathers as a means of nest crypsis is described and illustrated in an incubating Tataupa Tinamou (Crypturellus tataupa (Temminck, 1815)). An arboreal roosting Solitary Tinamou [Tinamus solitarius (Vieillot, 1819)] is shown to deliberately assume a tail up posture indicating Batesian mimicry of a large owl. It is hypothesised that the imbricated scales on the posterior tarsi of this species assist in assuming this posture, and that such a defence is necessary given the exposed perches on which they choose to roost and the notoriously poor flight capacity of members of this family. Keywords: Batesian mimicry. Crypturellus tataupa. Nest defence. Paraguay. Tataupa Tinamou. Resumo: Observações do comportamento defensivo de duas espécies de Tinamidae foram descritas. É descrito e ilustrado o uso de penas subcaudais como mecanismo de crípse do ninho por um espécime de inhambu-chintã (Crypturellus tataupa (Temminck, 1815)), que estava encubando os ovos. Também foi registrado um espécime de macuco [Tinamus solitarius (Vieillot, 1819)] que estava empoleirado no galho de uma árvore e, quando perturbado, ergueu a cauda, assumindo a aparência de uma coruja, possivelmente um exemplo de mimetismo Batesiano. -
First Ornithological Inventory and Conservation Assessment for the Yungas Forests of the Cordilleras Cocapata and Mosetenes, Cochabamba, Bolivia
Bird Conservation International (2005) 15:361–382. BirdLife International 2005 doi:10.1017/S095927090500064X Printed in the United Kingdom First ornithological inventory and conservation assessment for the yungas forests of the Cordilleras Cocapata and Mosetenes, Cochabamba, Bolivia ROSS MACLEOD, STEVEN K. EWING, SEBASTIAN K. HERZOG, ROSALIND BRYCE, KARL L. EVANS and AIDAN MACCORMICK Summary Bolivia holds one of the world’s richest avifaunas, but large areas remain biologically unexplored or unsurveyed. This study carried out the first ornithological inventory of one of the largest of these unexplored areas, the yungas forests of Cordilleras Cocapata and Mosetenes. A total of 339 bird species were recorded including 23 restricted-range, four Near-Threatened, two globally threatened, one new to Bolivia and one that may be new to science. The study extended the known altitudinal ranges of 62 species, 23 by at least 500 m, which represents a substantial increase in our knowledge of species distributions in the yungas, and illustrates how little is known about Bolivia’s avifauna. Species characteristic of, or unique to, three Endemic Bird Areas (EBAs) were found. The Cordilleras Cocapata and Mosetenes are a stronghold for yungas endemics and hold large areas of pristine Bolivian and Peruvian Upper and Lower Yungas habi- tat (EBAs 54 and 55). Human encroachment is starting to threaten the area and priority conser- vation actions, including designation as a protected area and designation as one of Bolivia’s first Important Bird Areas, are recommended. Introduction Bolivia holds the richest avifauna of any landlocked country. With a total of 1,398 species (Hennessey et al.
