A DISTINCTIVE NEW SPECIES OF TYRANT FLYCATCHER (PASSERIFORMES: TYRANNIDAE: CNIPODECTES) FROM SOUTHEASTERN PERU
A distinctive new species of twistwing from southeastern Peru is described, which suggests that it may be restricted to larger blocks of forest dominated by bamboo (Guadua spp.), a habitat poorly surveyed in Amazonia.
PATTERNS OF SPECIES COMPOSITION AND ENDEMISM IN THE NORTHERN NEOTROPICS: A CASE FOR CONSERVATION OF MONTANE AVIFAUNAS
A review of the composition of five montane avifaunas in northwestern South America and southern Central America confirmed the distinctness of these com- munities from adjacent lowland areas.…
The Effects of Area and Habitat Heterogeneity on Bird Richness and Composition in High Elevation Wetlands (“Bofedales”) of the Central Andes of Peru
Few species-rich microhabitats may contribute more to richness than many species-poor ones which is not predicted by the habitat heterogeneity hypothesis, and disentangling the influence of area and habitat heterogeneity on species richness is important to establish conservation priorities that ensure bofedales integrity under imminent climate change.

A NEW METHOD OF PREPARATION TO IDENTIFY ARTHROPODS FROM STOMACH CONTENTS OF BIRDS
--A micropaleontology method modified for the study of fragments of arthropods in stomach contents of birds is described. Fragments are sorted then mounted with gum tragacanth onto numbered grids of…

The biography compiles public records, publications, as well as personal memoirs to describe the context in which Erwin’s studies with carabid beetles evolved as formalization of concepts, such as biological diversity, megadiverse countries, biodiversity loss, and conservation biology, will become central for science in the upcoming years.
Ectoparasitism by Chigger Mite Larvae (Acari: Trombiculidae) in a Wintering Population of Catharus ustulatus (Turdidae) in Southeastern Peru
Ectoparasitic prevalence and intensity in long-distance migratory birds might add risks to an already hazardous journey because ectoparAsitic variation and other selective pressures experienced by individuals at each locality not only may be a cause of within-site mortality, but may be carried over to subsequent sites and affect reproductive success and survival.
