  • 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.

  • Bird Ecology, Conservation, and Community Responses
    BIRD ECOLOGY, CONSERVATION, AND COMMUNITY RESPONSES TO LOGGING IN THE NORTHERN PERUVIAN AMAZON by NICO SUZANNE DAUPHINÉ (Under the Direction of Robert J. Cooper) ABSTRACT Understanding the responses of wildlife communities to logging and other human impacts in tropical forests is critical to the conservation of global biodiversity. I examined understory forest bird community responses to different intensities of non-mechanized commercial logging in two areas of the northern Peruvian Amazon: white-sand forest in the Allpahuayo-Mishana Reserve, and humid tropical forest in the Cordillera de Colán. I quantified vegetation structure using a modified circular plot method. I sampled birds using mist nets at a total of 21 lowland forest stands, comparing birds in logged forests 1, 5, and 9 years postharvest with those in unlogged forests using a sample effort of 4439 net-hours. I assumed not all species were detected and used sampling data to generate estimates of bird species richness and local extinction and turnover probabilities. During the course of fieldwork, I also made a preliminary inventory of birds in the northwest Cordillera de Colán and incidental observations of new nest and distributional records as well as threats and conservation measures for birds in the region. In both study areas, canopy cover was significantly higher in unlogged forest stands compared to logged forest stands. In Allpahuayo-Mishana, estimated bird species richness was highest in unlogged forest and lowest in forest regenerating 1-2 years post-logging. An estimated 24-80% of bird species in unlogged forest were absent from logged forest stands between 1 and 10 years postharvest.

  • Juvenile Resilience and Adult Longevity Explain Residual Populations of the Andean Wax Palm Ceroxylon Quindiuense After Deforestation
    Juvenile Resilience and Adult Longevity Explain Residual Populations of the Andean Wax Palm Ceroxylon quindiuense after Deforestation María José Sanín1*, Fabien Anthelme2,3, Jean-Christophe Pintaud3, Gloria Galeano1, Rodrigo Bernal1 1 Instituto de Ciencias Naturales, Universidad Nacional de Colombia, Bogotá, Distrito Capital, Colombia, 2 Botanique et Bioinformatique de l’Architecture des Plantes, Recherche Agronomique pour Le Développement, Institut de recherche pour le développement, Montpellier, Hérault, France, 3 Botanique et Bioinformatique de l’Architecture des Plantes and Diversité Adaptation et Développement des plantes, Institut de recherche pour le développement, Montpellier, Hérault, France Abstract Wax palms are an important element of the cloud forests in the tropical Andes. Despite heavy deforestation, the density of adults seems to be similar in deforested pastures as in forests. We aimed to infer the mechanisms responsible for this apparent resilience in pastures and we tested two hypotheses to explain it: 1) adult palms survived in pastures because they were spared from logging, and 2) adults occurred in pastures through the resilience of large juvenile rosettes, which survived through subterranean meristems and later developed into adults. For this purpose, we characterized the demographic structure of C. quindiuense in a total of 122 plots of 400 m2 in forests and pastures at two sites with contrasted land use histories in Colombia and Peru. Additionally, we implemented growth models that allowed us to estimate the age of individuals at four sites. These data were combined with information collected from local land managers in order to complete our knowledge on the land use history at each site. At two sites, the presence of old individuals up to 169 years and a wide age range evidenced that, at least, a portion of current adults in pastures were spared from logging at the time of deforestation.

Many trip reports provide GPS waypoints for navigation. I used GoogleEarth/ Maps, which worked fine for most locations (not for El Paujil reserve). I paid $10/day for AT&T to hook me up to Claro, Movistar, or Tigo through their Passport program. Others get a local SIM card so that they have a Colombian number (cheaper, for sure); still others use GooglePhones, which provide connection through other providers with better or worse success, depending on the location in Colombia. For transportation, I used a rental 4x4 SUV to reach places with bad roads but also, in northern Colombia, a subcompact rental car as far as Minca (hiked in higher elevations, with one moto-taxi to reach El Dorado lodge) and for La Guajira. I used regular taxis on few occasions. The only roads to sites for Fuertes’s Parrot and Yellow-eared Parrot could not have been traversed without four-wheel drive and high clearance, and this is important to emphasize: vehicles without these attributes would have been useless, or become damaged or stranded. Note that large cities in Colombia (at least Medellín, Santa Marta, and Cartagena) have restrictions on driving during rush hours with certain license plate numbers (they base restrictions on the plate’s final numeral).
