“…The presence of more migratory than resident species, mainly in winter, is similar to what was observed in Las Garzas Lagoon (Verdugo-Munguía & Gómez-del Castillo, 2012) and in Cuyutlán Lagoon (Mellink & Riojas-López, 2008). The opposite occurred in the estuaries of La Manzanilla, El Salado, and Rancho Bueno (Amador et al, 2006;Cupul-Magaña, 2000;Hernández-Vázquez, 2000), where there were more resident species reported. Low diversity values were caused by differences in the number of individuals of migratory and resident species during winter, since the Shannon-Weaver index combines the number of species and the relative abundance.…”

“…Several migratory species arrive to rest and feed during this time of year, mainly on substrates that have been exposed by the decrease in water levels. For example, shorebirds were found mainly on sandy substrates and mud flats, whereas ducks and rails chose open areas with submerged vegetation and shallow areas with weak circulation and low salinity (Hernández-Vázquez, 2000;Hernández-Vázquez, 2005a;Hernández-Vázquez & Mellink, 2001;Hernández-Vázquez et al, 2010;Ysebaert et al, 2000). This coincides with the characteristics of substrates used by shorebirds and ducks and rails during the cold season.…”

“…These conditions influenced the fact that some individuals aggregated to rest and/or feed, as prey capture is more effective in shallower areas (David, 1994). In some Jalisco wetlands, such as La Manzanilla Estuary, Barra de Navidad Lagoon, and Agua Dulce Lagoon, as well as Cuyutlán Lagoon in Colima, the number of species, number of individuals, and diversity were influenced by variations in water levels caused by tide changes, and the existence of substrates suitable for foraging (Hernández-Vázquez, 2000: Hernández-Vázquez, 2005aHernández-Vázquez, 2005b;Hernández-Vázquez et al, 2012;Mellink & de la Riva, 2005).…”

Introduction: Aquatic birds (AB) are usually associated with wetlands, which provide refuge, food, and/or nesting sites for resident and migratory species. Despite their ecological importance, there is little knowledge on AB in some tropical environments, such as those found on the Colima coast. Objective: To investigate the spatial and temporal composition of the AB community in Juluapan Lagoon, Colima, Central Mexican Pacific. Methods: Monthly counts were conducted between June 2017 and May 2018 during low-tide conditions to record habitat use by AB. Species richness and bird counts were obtained to compare sampling areas; mean richness and number of individuals were compared between seasons. Results: We detected 53 species and 5 750 individuals. The highest species richness and relative abundance values were obtained in winter at the lagoon area farthest from the connection with the marine system, where anthropogenic activity is lower. Diversity was greater in zones 2 and 3 in spring, summer, and fall. Muddy flats were the most used environment, and the most frequent activity was resting. Nesting activity was only recorded in the middle of the lagoon at the mangrove during spring. Shorebirds and waders were the most dominant groups in the bird community of the Juluapan lagoon. Conclusions: This coastal wetland is a site of great biological importance for aquatic birds; thus, conservation measures should be implemented, and there should be a continuous study of the effects of anthropogenic pressure.

“…Mediante el programa InfoStat 2011e-free, se verificó el supuesto de normalidad de los datos y homogeneidad de varianza, se aplicó ANOVA y prueba de múltiples rangos (diferencias mínimas significativas); se establecieron cálculos de abundancia relativa en porcentaje, con las siguientes categorías: residente continuo (RC) (especies que habitan exclusivamente el lugar), visitante regular (VR) (permanecen parte del día en el jagüey) y visitante ocasional (VO) (especies que llegan a forrajear o beber agua y se van de inmediato) (Hernández-Vásquez, 2000).…”

Se llevó a cabo un inventario de la avifauna residente o visitante asociada a un jagüey o laguna artificial de la costa Caribe de Colombia, que se utiliza como reserva de agua para el ganado vacuno en la época seca y que también sirve como fuente de agua para las comunidades cercanas. Se hizo el registro de individuos de cada especie durante la época seca e inicio de la época de lluvias, mediante el método de observación constante, por periodos de tiempo preestablecidos, usando dos puntos fijos de conteo. Se determinó una comunidad de aves que mostró 28 especies pertenecientes a 15 familias, de las cuales, se identificaron como residentes continuos (RC), 11 especies (39,3%), como visitantes regulares (VR), 7 especies (25%) y como visitantes ocasionales (VO), 10 especies (35,7%), lo que permite aceptar la importancia estratégica de este tipo de lagunas en la conservación de la biodiversidad local, mostrando que los agroecosistemas pueden conservar una sustancial parte de la biodiversidad de su anterior ecosistema natural.

Oaxaca hosts one of the greatest biodiversity in México, occupying first place in avian diversity compared to other regions of the country. However, the area is undergoing serious problems such as high deforestation rates, soil erosion and over exploitation and extinction of species. These factors have all contributed to the current loss of biodiversity. Also, biological inventories are still incomplete. One of the least explored sites is the semiarid zone of Tehuantepec isthmus, around the locality of Santa Maria del Mar, Oaxaca, México. The area includes floodable grasslands, mangrove areas and dry forest, providing a range of potential habitats for different species. Our objective was to evaluate the effect of temporal lakes on spatial and temporal composition of the avifauna in Santa Maria del Mar, in order to generate information regarding this group within the region and the state, and to understand the importance of flood areas for resident and transitory birds. We conducted 12 avifauna surveys between July 2006 and June 2008, and established two transects of 2km length in each of four habitat types (beach, grassland, dry forest, and mangrove). We found a total of 75 species, corresponding to 16 orders and 30 families. Within an area of 26km 2 , we significantly found 10.1% of the total number of bird species recorded for the entire state, and 6.6% of the total reported in Mexico. The families most represented were: Ardeidae, Laridae and Scolopacidae. Over the entire study period, dry forest was the most diverse habitat; followed by mangrove, grassland and the beach. Of all the species recorded, 38.6% were found at the edge or in the temporal lakes. We found a significant difference in species composition between seasons in the grassland, but no difference in the other habitats. Our results showed a significant effect of temporary lakes on avian diversity during the wet season; it also demonstrated the importance of grassland conservation given its relevance for presence of waterbirds. We suggested a continued and more intense monitoring; and proposed the designation of the area as an important Conservation Bird Area (AiCA). Rev. Biol. Trop. 62 (4): 1523-1533. Epub 2014 December 01.Key words: bird diversity, important Conservation Bird Area, AiCA, season effect, waterbirds, water bodies.Mexico is considered one of the five megadiverse countries in the world; however, the country is undergoing a profound ecological crisis increased by global warming, high rates of deforestation, soil erosion and over exploitation and extinction of species. These factors have all contributed to the current loss of biodiversity (Toledo, 1992;Primack, Rozzi, Feinsinger, Dirzo, & Massardo, 2001;Martínez-Meyer, Sosa-Escalante, & Noguera, 2014). in the interior of the country, the state of Oaxaca hosts one of the greatest biodiversity (García-Mendoza, Ordóñez-Díaz, & BrionesSalas, 2004); it occupies the first place in terms of amphibians and birds diversity of (NavarroSigüenza et al., 2014;Parra-Olea, Flores-villela, &...
