Nocturnal birds have many anatomical and behavioral specializations, related to foraging in low light conditions. One of those strategies is the complementation of low intensity visual stimuli with auditory, tactile or olfactory cues. Nightjars are nocturnal-crepuscular foragers, that feed on flying insects by aerial pursuit (Fig. 1A-B). However, t...

The genus Telmatobius Wiegmann, 1834 is composed of a wide variety of species and is one of the most diverse native com- ponents of the high-altitude Andean environments. The species of the genus present in Chile are considered as endangered, critically endangered or data deficient. We isolated and evaluated 44 microsatellites in 80 individuals of...

On the basis of molecular and morphological evidence, we evaluated the taxonomic identity of two species of Andean frogs of the genus Telmatobius: Telmatobius pefauri and T. zapahuirensis, present in the western Andean slopes at the northern extreme of Chile. We also investigated the taxonomic assignment of five populations of Telmatobius recently...

Several studies have suggested that penguins are undergoing a major restructuring of their feeding habits and distribution after drastic climatic changes in the Antarctic Peninsula region. With the objective of estimating potential medium-term and inter-annual variations in trophic niche, we measured δ 15N and δ 13C in feather samples of pygoscelid...

During the Pleistocene and Holocene, the southwest Andean Altiplano (17°-22°S) was affected by repeated fluctuations in water levels, high volcanic activity and major tectonic movements. In the early Holocene the humid Tauca phase shifted to the arid conditions that have lasted until the present, producing endorheic rivers, lakes, lagoons and wetla...

The positive animals we identified originated from a single location on the Antarctic Peninsula, which suggests recent introduction of this AIV H5N5 in the colonies sampled. Antarctica is refuge for most penguin colonies, including the near-threatened emperor penguins. Previous reports suggested that AIV could have caused Adélie penguin chick death...

Nocturnal birds present several visual specializations, such as frontally oriented eyes, associated to scotopic visual conditions. Nightjars (Aves: Caprimulgidae) are predators that capture flying insects at night. Here we describe the main features of the visual system of the Band-winged Nightjar (Systellura longirostris). The visual field, determ...

Por décadas, el registro fósil de vertebrados en Chile fue exiguo, restringido a pocos hallazgos, muchos de ellos fortuitos. En contraposición a esta situación, grandes figuras de la ciencia, entre ellos Charles Darwin, Rudolph Philippi y Claude Gay, entre otros, notaron tempranamente el valor de este registro, a la vez que dieron a conocer desde e...

Chilean Rhinocryptidae (Avian): speciation. We are convinced that the behaviour and the local interaction between "trophics groups" of these sister lineages drive the speciation of these undergrowth terrestrial birds. We also have the persuasion that the striking similarities between these sister lineages is due to their closely "mode of life" and...

Rhinella atacamensis and Rhinella arunco are sister species which, together, are distributed from 25°S to 38°S in Chile. Until recently they were considered to be allopatric, with the dividing line around 32°S, but in 2007 a possible zone of secondary contact was found in the Estero Pupío (32°S). We investigated the species status of adult individu...

Paleogene records of birds in the Eastern margin of the Pacific Ocean have increased in recent years, being almost exclusively restricted to fossil Sphenisciformes (penguins). New avian remains (Ornithurae, Neornithes) from Middle-to-Late Eocene levels of the Estratos de Algarrobo unit, in Algarrobo, central Chile, are disclosed in the present work...

We studied the respiratory surface density and the thickness of the air-blood barrier in the Picui Ground Dove (Columbina picui), and compared it with Eared Dove (Zenaida auriculata) and Blacked-winged Ground Dove (Metropelia melanoptera), two larger species. As expected, Columbina picui BMR and VO2max showed higher values than those of the larger...

The southern part of the Altiplano of the Andes Range is characterized by a complex hydrography, due to an intense geologic activity and the effects of the Pleistocene glaciations. This has produced a high degree of diversity at the species level in some aquatic taxa (e.g., fish and amphibians), which suggests that these same processes have produce...
