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. -

Nature Colombia Trip Report - Eastern Andes & Mid-Magdalena´S Valley 2018
www.naturecolombia.com EASTERN ANDES & MID-MAGDALENA´S VALLEY 3rd March – 8th March 2018 Sword-billed Hummingbird (Ensifera ensifera) is characterized by its unusually long bill size; it is the only bird to have a beak longer than the length of its body. As all the pictures in this report, this picture was taken during this trip, in the Hummingbird Observatory Reserve - Bogotá. Nature Colombia Tour Leader: Roger Rodriguez Ardila 2 Nature Colombia Trip Report - Eastern Andes & Mid-Magdalena´s Valley 2018 Colombia is famed for its extraordinary diversity of birds. Thanks to its wide variety of landscapes and climates, Colombia is a megadiverse country with some of the highest biodiversity on the planet. Regardless of size, Colombia holds almost 20% of all birds in the planet (1,944 species, with new species still being discovered). Robert Holt, Lynne and I traveled together for 5 days, visiting some birding sites in the Eastern Andes and the Mid-Magdalena´s Valley looking for some endemic and special birds of this areas. In overall the trip was fast paced, designed to visit as much birding sites as we could of these two very different kind of environments. That also forced us to be in the car for long hours most of the days. We recorded 235 species (47 families), including 11 endemic bird species and 7 near-endemics. This was in spite of the complicated conditions mentioned before.

The Generic Distinction of Pied Woodpeckers
THE GENERIC DISTINCTION OF PIED WOODPECKERS M. RALPH BROWNING, 170 JacksonCreek Drive, Jacksonville,Oregon 97530 ABSTRACT: The ten speciesof New World four-toedwoodpeckers (scalaris, nuttallii, pubescens, villosus, stricklandi, arizonae, borealis, albolarvatus, lignarius,and m ixtusand the two borealthree-toed species (arcticus and tridactylus), currentlycombined in the genusPicoides, differ, in additionto the numberof toes,in modificationsof the skull,ribs, the belly of the pubo-ischio-femoralismuscle, head plumage,and behavior. I recommendthat the genericname Dryobates be reinstituted for the New World four-toedwoodpeckers. There are three generalmorphological groups of pied woodpeckers,a groupof nine four-toedspecies of the New World, a groupof 22 four-toed speciesof the Old World, and a groupof two three-toedspecies straddling bothregions. ! referto thesegroups of piedwoodpeckers beyond as the New World,Old World,and three-toedgroups. The three-toedspecies have long beenin the genusPicoides Lac•p•de, 1799, but the four-toedgroups have been combinedat the genericlevel in differentways. All four-toedpied woodpeckerswere long includedin the genusDryobates Boie, 1826, later changed to Dendrocopos Koch, 1816 an earlier name (Voous 1947, A.O.U. 1947, Peters 1948). Despite the differencein number of toes, Dendrocoposwas combined with Picoidesbecause of generalsimilarities in anatomy (Delacour 1951, Short 1971a), plumage and behavior (Short 1974a), and vocalizations(Winkler and Short 1978). The A.O.U (1976) followedthis mergerof the genera.On the basisof skeletalcharacters Rea (1983) was skepticalof the merger,but he did not providedetails. On the otherhand, Ouellet(1977), concludingthat the two generadiffer in external morphologyand some behaviors and vocalizations, separated the Old World four-toedwoodpeckers in Dendrocoposand three-toedand New World four-toedwoodpeckers in Picoides.The A.O.U. -
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. Palkachupe Cotinga in the early morning light brooding young near Apolo (Eustace Barnes). 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. -
Brazil's Eastern Amazonia
The loud and impressive White Bellbird, one of the many highlights on the Brazil’s Eastern Amazonia 2017 tour (Eduardo Patrial) BRAZIL’S EASTERN AMAZONIA 8/16 – 26 AUGUST 2017 LEADER: EDUARDO PATRIAL This second edition of Brazil’s Eastern Amazonia was absolutely a phenomenal trip with over five hundred species recorded (514). Some adjustments happily facilitated the logistics (internal flights) a bit and we also could explore some areas around Belem this time, providing some extra good birds to our list. Our time at Amazonia National Park was good and we managed to get most of the important targets, despite the quite low bird activity noticed along the trails when we were there. Carajas National Forest on the other hand was very busy and produced an overwhelming cast of fine birds (and a Giant Armadillo!). Caxias in the end came again as good as it gets, and this time with the novelty of visiting a new site, Campo Maior, a place that reminds the lowlands from Pantanal. On this amazing tour we had the chance to enjoy the special avifauna from two important interfluvium in the Brazilian Amazon, the Madeira – Tapajos and Xingu – Tocantins; and also the specialties from a poorly covered corner in the Northeast region at Maranhão and Piauí states. Check out below the highlights from this successful adventure: Horned Screamer, Masked Duck, Chestnut- headed and Buff-browed Chachalacas, White-crested Guan, Bare-faced Curassow, King Vulture, Black-and- white and Ornate Hawk-Eagles, White and White-browed Hawks, Rufous-sided and Russet-crowned Crakes, Dark-winged Trumpeter (ssp. -
Richness of Plants, Birds and Mammals Under the Canopy of Ramorinoa Girolae, an Endemic and Vulnerable Desert Tree Species

SUMMARY Dominant woody vegetation in arid ecosystems supports different species of plants and animals largely dependent on the existence of these habitats for their survival. The chica (Ramorinoa girolae) is a woody leguminous tree endemic to central-western Argentina and categorized as vulnerable. We evaluated 1) richness of plants, birds and mammals associated with the habitat under its canopy, 2) whether richness is related to the morphological attributes and to the features of the habitat under its canopy, and 3) behavior displayed by birds and mammals. We recorded presence/absence of plants under the canopy of 19 trees in Ischigualasto Provincial Park. Moreover, we recorded abundance of birds and mammals and signs of mammal activity using camera traps. -
Crested Quetzal (Pharomachrus Antisianus) Preying on a Glassfrog (Anura, Centrolenidae) in Sierra De Perijá, Northwestern Venezuela
Revista Brasileira de Ornitologia, 22(4), 419-421 SHORTCOMMUNICATION December 2014 Crested Quetzal (Pharomachrus antisianus) preying on a Glassfrog (Anura, Centrolenidae) in Sierra de Perijá, northwestern Venezuela Marcial Quiroga-Carmona1,3 and Adrián Naveda-Rodríguez2 1 Centro de Ecología, Instituto Venezolano de Investigaciones Científicas, Caracas 1020-A, Apartado 2032, Venezuela. 2 The Peregrine Fund, 5668 West Flying Hawk Lane, Boise, ID 83709, U.S.A. 3 Corresponding author: [email protected] Received on 17 September 2014. Accepted on 8 November 2014. ABSTRACT: We report the predation of a glassfrog (Hyalinobatrachium pallidum) by a Crested Quetzal (Pharomachrus antisianus). The record was made in a locality in the Sierra de Perijá, near to the northern part of the border between Colombia and Venezuela, and consisted in observinga male P. antisianus vocalizing with a glassfrog in its bill. The vocalizations were answered by a female, which approached the male, took the frog with its bill and carried it into a cavity built on a landslide. Subsequent to this, the male remained near to the cavity until the female left it and together they abandoned this place. Based on the behavior observed in the couple of quetzals, and what has previously been described that this group of birds gives their young a diet rich in animal protein comprised of arthropods and small vertebrates, we believe that the couple was raising a brood at the time when the observation was carried out. KEYWORDS: Anurophagy, diet, Hyalinobatrachium, Trogonidae, Trogoniformes. The consumption of animal protein is a behavior a behavior also reported for P. pavoninus (Lebbin 2007) exhibited by most of the species of the family Trogonidae. -
21 Sep 2018 Lists of Victims and Hosts of the Parasitic
version: 21 Sep 2018 Lists of victims and hosts of the parasitic cowbirds (Molothrus). Peter E. Lowther, Field Museum Brood parasitism is an awkward term to describe an interaction between two species in which, as in predator-prey relationships, one species gains at the expense of the other. Brood parasites "prey" upon parental care. Victimized species usually have reduced breeding success, partly because of the additional cost of caring for alien eggs and young, and partly because of the behavior of brood parasites (both adults and young) which may directly and adversely affect the survival of the victim's own eggs or young. About 1% of all bird species, among 7 families, are brood parasites. The 5 species of brood parasitic “cowbirds” are currently all treated as members of the genus Molothrus. Host selection is an active process. Not all species co-occurring with brood parasites are equally likely to be selected nor are they of equal quality as hosts. Rather, to varying degrees, brood parasites are specialized for certain categories of hosts. Brood parasites may rely on a single host species to rear their young or may distribute their eggs among many species, seemingly without regard to any characteristics of potential hosts. Lists of species are not the best means to describe interactions between a brood parasitic species and its hosts. Such lists do not necessarily reflect the taxonomy used by the brood parasites themselves nor do they accurately reflect the complex interactions within bird communities (see Ortega 1998: 183-184). Host lists do, however, offer some insight into the process of host selection and do emphasize the wide variety of features than can impact on host selection.
