El conflicto humano-vida silvestre es omnipresente en las sociedades rurales de México. Identificar las percepciones de los pobladores de estas regiones hacia especies que generan conflicto puede ayudar a disminuir esta situación. Se presentan los resultados del análisis de entrevistas semiestructuradas de las percepciones que los agricultores tien...
Preprint
One strategy animals perform to cope scarcity of food resources is to shift in number of individuals according towards areas with available resources. This strategy can be more marked in species that are constrained by high energetic requirements such as hummingbirds. We aim to determine the extent to which the availability of food resources could...

The transformation of natural systems into urban cities represents a radical habitat modification and one that generates species-specific effects on bat communities. Cities present heterogeneous mosaics of urban conditions, which the bats can inhabit differentially by utilizing their intrinsic characteristics. We expected bat species richness, numb...
Article
Geographic variation in acoustic signals may arise in vocal learning species due to processes of cultural evolution and population dynamics, but few studies have evaluated geographic vocal variation for large-bodied non-oscine species such as parrots. We evaluated similarity in a contact call of the Military Macaw (Ara militaris) among three popula...

Background Dietary specialization should arise when there is a relatively high abundance of a particular resource, where animals may select food items to obtain an optimal diet that maximizes energy intake. Large-bodied psittacines frequently exhibit a narrow dietary niche with specific habitat use, but few studies have determined whether psittacin...
Article
Niche partitioning is a strategy that favors the coexistence of sympatric species and prevents resource competition. Resource partitioning not only occurs along a temporal and spatial axis, but also within the niche breadth. The lesser long-nosed (Leptonycteris yerbabuenae) and the Pallas's long-tongued (Glossophaga soricina) bats are sympatric thr...
Article
The influence of climate extremes on tree phenology or cavity resources, and the consequences for threatened species, are poorly understood. We determined flowering and fruiting phenology, and availability of tree-cavities and snags in deciduous and semi-deciduous tropical dry forest from 2009 to 2016, prior-to and following landfall by hurricanes...
Article
Full-text available
Nonnative Monk Parakeets have been reported in increasing numbers across many cities in Mexico, and were formally classified as an invasive species in Mexico in late 2016. However, there has not been a large-scale attempt to determine how international pet trade and national and international governmental regulations have played a part in colonizat...
Article
Psittaciformes (parrots, cockatoos) are among the most endangered birds, with 31% of Neotropical species under threat. The drivers of this situation appear to be manifold and mainly of anthropogenic origin. However, this assessment is based on the last extensive consultation about the conservation situation of parrots carried out in the 1990s. Give...

Background Understanding the role of avian vocal communication in social organisation requires knowledge of the vocal repertoire used to convey information. Parrots use acoustic signals in a variety of social contexts, but no studies have evaluated cross-functional use of acoustic signals by parrots, or whether these conform to signal design rules...
Article
Full-text available
Parrots (Order Psittaciformes) are secondary cavity-nesters that depend on existing cavities for nest sites, and consume plant resources of fruits, seeds, and flowers that are highly variable, but little is known of resource selectivity by parrots, or how they deal with variable environments. We reviewed published studies of nest-cavity use by parr...
Article
Full-text available
Large-bodied secondary cavity-nesters are constrained to use cavities of sufficient size to permit access, while also selecting characteristics to reduce predation. However, no information exists on nest-site availability for large-bodied secondary cavity-nesters in tropical forests. We located 12 tree-cavity nests of the threatened Military Macaw...
Article
Stochastic and catastrophic events may strongly impact the dynamics of wild populations. Annual fluctuations in rainfall may affect parrot populations, but few studies address the impact of other stochastic or catastrophic events on their population dynamics. The Maroon-fronted Parrot Rhynchopsitta terrisi is an endangered species that nests coloni...
Article
Behavioral plasticity is a strategy employed by many species to cope with both naturally occurring and human-mediated environmental variability. Such plasticity may be especially important for long-lived and wide-ranging species, such as parrots, that likely face great temporal and spatial variation within their long lifespans, and are often dispro...

Blood and feather samples, as well as oropharyngeal and cloacal swabs, were collected from nine free-ranging Amazona auropalliata between January and May 2009 in two highly modified landscapes in northern Costa Rica. Samples were tested for avian circovirus, avian polyomavirus, avian influenza, Chlamydophila psittaci, Borrelia burgdorferi sensu lat...
Article
Full-text available
Studies of avian vocal dialects commonly find evidence of geographic and acoustic stability in the face of substantial gene flow between dialects. The vocal imitation and reduced dispersal hypotheses are alternatives to explain this mismatch between vocal and genetic variation. We experimentally simulated dispersal in the yellow-naped amazon (Amazo...

Evolutionary theory predicts birds should adjust the sex ratio of their broods in response to external factors that differentially affect the reproductive value of each sex. We examined the brood sex ratio in the Lilac-crowned Parrot (Amazona finschi) in relation to climate, hatching date, and hatching order. We used polymerase chain reaction ampli...
Article
We fitted radiotransmitters to 68 lilac-crowned parrot (Amazona finschi) fledglings from 1996 to 2003 to determine the survival and development of juveniles during their first year after leaving the nest. Overall, first-year survival was 73% (CI = 53–94%) and all mortalities occurred within 5 weeks of fledging, with highest mortality in the first w...
Article
Full-text available
Resource availability in a heterogeneous environment and density-dependent processes may influence the spatial distribution of individuals among habitats. The distribution of nests of secondary cavity nesters is rarely clumped because the birds are constrained by the distribution of existing cavities as nest resources. In this study, to evaluate th...
Article
Parrot populations are being increasingly pressured to occupy modified or fragmented landscapes, yet little is known of the habitat requirements of most species, particularly with regard to the effects on breeding habitat. We evaluated nesting habitat of the lilac-crowned parrot Amazona finschi in the modified landscape of coastal Michoacan in Mexi...
Article
Cultural evolution is an important force in creating and maintaining behavioral variation in some species. Vocal dialects have provided a useful model for the study of cultural evolution and its interactions with genetic evolution. This study examined the acoustic and geographic changes in vocal dialects over an eleven-year span in the yellow-naped...
Article
We used radio-telemetry techniques to determine hourly activity patterns of 29 juvenile Lilaccrowned Parrots (Amazona finschi) during 1996-2000 in tropical dry forest of Jalisco, Mexico. Parrots had two peak activity periods--early morning and local movement. Individuals were generally inactive and did not change location for 5-6 hr during the midd...
