Anthropogenic activities are the major drivers of biodiversity loss, and human pressure of capture for trade is closely associated with decreasing population trends of Psittaciformes. We evaluated reproductive output and daily survival rate of 45 nests of the threatened Northern Mealy Amazon (Amazona guatemalae) in tropical moist forest of southern...
Trogonidae make up a family of birds with a mixed diet composed of fruit and animal matter. However, there is little research examining the foraging ecology of Trogon citreolus in regenerating tropical forest. We studied T. citreolus abundance and diet from November 2020 to April 2022 in a regenerating dry tropical forest of Central Pacific Mexico....
DOI https://doi.org/10.48204/j.mesoamericana.v26n2.a5981 RESUMEN. Se reporta la presencia del cenzontle norteño (Mimus polyglottos) en la Reserva Biológica privada Cerro Hermoso, que forma parte de la zona de influencia del Parque Nacional Lagunas de Chacahua, Oaxaca, México. En noviembre de 2023, con el uso de redes de niebla, se capturó un indivi...
En México el conocimiento de la dieta de las rapaces nocturnas es insuficiente. Durante noviembre 2016 a febrero 2017, evaluamos la dieta la lechuza Tyto alba durante la época reproductiva en una pequeña área agrícola al noroeste del estado de Guerrero, México. Analizamos un total de 24 egagrópilas y 44 elementos en la dieta para dos nidos. Los mam...
Knowledge of Mexican nocturnal raptors diet is scarce. We evaluated the diet of the Barn-owl Tyto alba during its breeding season in a small agricultural area the northwestern state of Guerrero, Mexico, from November 2016 to February 2017. We analyzed 24 owl-pellets with 44 prey items from two nests. Small mammals are the principal food item of the...
Introduction: Seasonal phenological variations in tropical forests cause changes in food resource availability. Animals use foraging strategies to follow the food supply in these settings. The Orange-fronted Parakeet (Eupsittula canicularis) mainly inhabits the tropical dry forest of the Mexican Pacific to Northwest Costa Rica, although little is k...
El perico frente naranja, Eupsittula canicularis anida en termiteros
arbóreos durante la época seca del año, pero existe limitado conocimiento de su ecología reproductiva. En este estudio se reportan las características del sitio de anidación y el comportamiento reproductivo del perico frente naranja para un nido registrado en vegetación de sucesió...
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...
Invasive species are a main cause of biodiversity loss, making it important to register their incursion into conserved, protected areas. We evaluated presence of the exotic Eurasian Collared-Dove (Streptopelia decaocto) in and around the Chamela-Cuixmala Biosphere Reserve, Jalisco, after hurricane disturbance. During March to May 2017 and 2018, we...
Background and Research Aims: Habitat amount plays an important role in determining the presence and abundance of bird species in modified landscapes, whereas habitat fragmentation has shown little effects. Toucans (Ramphastidae) and parrots (Psittacidae) are large-bodied primary consumers and among the most representative birds in Neotropical fore...
Birds in seasonal environments cope with marked phenological changes over the year, and have to deal with additional challenges of extreme climatic events such as hurricanes. Little is known regarding the response of raptors to seasonality or to hurricane disturbance. We evaluated spatiotemporal variation in diversity of diurnal raptors in the trop...
Understanding the dynamics of animal responses to heterogeneity of food resources in modified landscapes is crucial for the conservation of threatened species. We evaluated dietary strategies of the Northern Mealy Amazon in a modified landscape of tropical moist forest in Los Chimalapas, Mexico. We established 30 phenology transects (200 × 6 m) to...
The high rate of conversion of tropical moist forest to secondary forest makes it imperative to evaluate forest metric relationships of species dependent on primary, old-growth forest. The threatened Northern Mealy Amazon (Amazona guatemalae) is the largest mainland parrot, and occurs in tropical moist forests of Mesoamerica that are increasingly b...
The increasing conversion of primary tropical moist forest to secondary forest may have consequences for threatened, large-bodied cavity-nesters, such as the Northern Mealy Amazon (Amazona guatemalae). We determined availability and characteristics of tree-cavities in 24 1-ha survey plots in Los Chimalapas, southeast Mexico, with 9 plots in evergre...
Los recursos desempeñan un papel decisivo en la dinámica poblacional de las aves. Sin embargo, distintos factores puede modificar la disponibilidad de los recursos en el ambiente. Los psitácidos, para su supervivencia y reproducción, dependen de recursos (hábitat, alimento y sitios de anidación) que muestran heterogeneidad espacial y temporal. Estu...
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...
RAPACES DIURNAS EN LA RESERVA DE BIOSFERA DE LOS TUXTLAS, MÉXICO: PRESENCIA ACTUAL Y ABUNDANCIA RELATIVA Poco se sabe sobre el estado actual de las poblaciones de rapaces en las zonas tropicales de México. De 2008 a 2010, estudiamos las rapaces diurnas residentes en la región de Los Tuxtlas, Veracruz. Se muestrearon hábitats de bosque con diferente...
La guacamaya verde (Ara militaris) es una especie considerada en peligro de extinción en México y hadesaparecido en estados del Pacífico sur. Sin embargo, no existen estudios actualizados sobre su distribución enlos estados donde todavía se puede encontrar. El objetivo principal de este estudio fue conocer su distribución enMichoacán. Se evaluaron...
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 Michoacan. We evaluated 215 l...
Habitat, abundance and conservation perspectives of parrots at Los Tuxtlas Bio-sphere Reserve, Veracruz, Mexico. – During the years of 2008–2010, we assessed the conservation status of parrot species in Los Tuxtlas, Veracruz, southeast Mexico, obtaining data on abundance, habi-tat use and date of pet trade. During our field studies, we visited site...
During the years of 2008-2010, we assessed the conservation status of parrot species in Los Tuxtlas, Veracruz, southeast Mexico, obtaining data on abundance, habitat use and date of pet trade. During our field studies, we visited sites that included all the terrestrial habitats in the region, from the mangrove forest at sea level to montane rain fo...
