Based on a series of 10-min point counts that were widely distributed throughout central-Mexico, I detected 175 species of birds within agricultural border strips. Migrant species (including partial migrants and long-distance migrants) constituted 49% (85) of the species in these border strips and 77% of the migrant species recorded on a broader su...

El conocimiento del uso de hábitat de las especies animales intenta comprender la estructura y dinámica de las comunidades y es útil para la evaluación e implementación de acciones de conservación en hábitats y especies que lo ameritan. Con el fin de comprender los patrones de uso de hábitat de las especies de aves del Distrito Minero El Oro-Tlalpu...

Birds contribute to the stability of ecosystems and represent a tool used to evaluate a variety of anthropogenic impacts. The area known as El Oro-Tlalpujahua Mining District in central Mexico was subjected to significant environmental impacts as a result of ore extraction, including profound habitat transformations, landscape changes, and the accu...

Presentamos los primeros registros del aguililla pecho-rojo (Buteo lineatus) para el estado de Michoacán, en el contexto de una revisión de sus registros para el centro-occidente de México. Los nuevos datos sugieren la fidelidad de individuos y su permanencia invernal en una zona suburbana al noroeste de la ciudad de Morelia, en Michoacán, durante...

Elevation gradient studies have strengthened the evaluation of changes in richness and composition of bird assemblages. They also provide information on environmental variables that determine bird distribution, and the variables that define their population structure. Our aim was to describe their variation through an elevational cline in Southern...

RESUMEN Analizamos la presencia y abundancia de palomas tropicales residentes en la Reserva de la Biosfera Los Tuxtlas, Veracruz, México durante las épocas reproductivas de 2010 y 2011. Se emplearon distintos métodos de con‐ teo para maximizar el registro del mayor número de especies y superar las dificultades del terreno y la vegetación. Muestream...

We analyzed the presence and abundance of tropical resident pigeons and doves (Columbidae) in Los Tuxtlas Biosphere Reserve, Veracruz, Mexico, during the breeding seasons of 2010 and 2011. We used different survey methods to maximize the detection of different species and overcome terrain and vegetation limitations. We surveyed the area mostly thro...

Motivated by the finding of consistent declining population trends in migrant landbird species in the northeastern United States, there emerged numerous studies throughout the 1990’s dealing with the breeding biology of Neotropical migratory species (Terborgh 1992, Hagan & Johnston 1992, Rappole 1995, Martin & Finch 1995). More recently, attention...

This report updates and summarizes the knowledge on the bird diversity of the Cupatitzio river sub-basin in Michoacan, Mexico. We gathered information on 8,967 records that made up a list of 301 species belonging to 52 bird families, representing 53.7% of the species and the 68.4% of the families known to the state of Michoacan, outstanding the fac...

We recorded the Red-legged Honeycreeper (Cyanerpes cyaneus) in some localities of the Sierra Madre del Sur. The species is listed in the bird's check-list of the state of Guerrero, but no specimens from these populations existed on scientific collections, and there were no records of the species in eastern Guerrero. We recorded adult and juvenile i...

The military macaw (Ara militaris) is an endangered species in Mexico, it has disappeared from states on the south Pacific. However, actual studies providing distribution information on the different states are inexistent. The main objective of this study was to provide information concerning its actual distribution on Michoacán. We evaluated 215 l...

Este trabajo representa una revisión y actualización de la avifauna del estado de Sonora, México. La revisión incluyó registros de 89 artículos y reportes, 16 008 especímenes depositados en colecciones zoológicas de diferentes museos y más de doscientos setenta y ocho mil registros que corresponden a observaciones de campo y datos de anillamiento g...

Riparian systems are dynamic and diverse despite their limited areal extent. They are especially important for breeding bird communities in southwestern US and are highly used as migratory corridors; however, their importance for wintering birds has not been assessed systematically. Information from 1,816 standard 10-min point counts was gathered a...

Un alto porcentaje de especies de aves terrestres dependen de la existencia de cavidades tanto en árboles vivos como muertos para su reproducción en bosques y selvas, lo que las hace vulnerables a las altas tasas de deforestación actuales. En Europa y Norteamérica los porcentajes de especies de aves con esta forma de anidación son entre el 4% y 5%....

In order to determine the effects of selective logging on pine-oak forest´s bird communities in central-western Mexico, we gathered information through 10-min point counts in plots without wood extraction and sites logged at different times in the past (1, 4, and 8 years). We did not find evidences to argue for effects of logging on bird communitie...

We present information on records of four pelagic bird species from the Coast of Michoacan, western Mexico, representing the first documented records for Michoacan State adn/or an extension of its known distributional range.

Cerro Prieto " Geothermal Field, the most important geothermal power plant in Mexico and Latin America, is located at the northern portion of Baja California, Mexico. Perforation activities began in 1964; by 1980 an evaporation pond was created to hold the water discharged from the generation plants and wells. During a winter sampling period (Febru...
