Introduction: wild birds are important for humans as biological control and seed dispersers, among others. In turn, they can be affected by changes in landscape structure. Objective: to analyze the composition and richness of avifauna in four vegetation types of San Ramón, Costa Rica, between May and August 2016. Methods: point sampling with a fixed 25m radius (75m between points, 10min per observation) produced 548 individuals from 27 families and 75 species. Results: the most abundant species were Ramphocelus passerinii, Turdus grayi, Crotophaga sulcirostris and Troglodytes aedon. Species richness and abundance were higher in pasture with high canopy cover, and in riverine forest, than in live fences and pastures with low canopy cover. Habitats with the most similarity were riverine forest and live fences. Additionally, 39% of the represented species were insectivorous, 23% frugivorous, 17% omnivorous, 16% carnivorous, 4% seed eaters, and 1% was nectar eater. Lastly, five species were “Forest Dependent” and six were “Indicative of Forest”. Conclusion: finally, it should be noted that the areas with the highest vegetation coverage, food availability and refuge areas were the ones with the highest number of species and the most similar sites are determined by the connectivity between them. |

Estas a su vez se pueden ver afectadas por los cambios en la estructura del paisaje. Objetivo: analizar la composición y riqueza de avifauna en cuatro tipos de cobertura vegetal en una comunidad del distrito de Peñas Blancas, San Ramón, Costa Rica entre mayo y agosto del 2016. Métodos: el muestreo de aves fue realizado mediante puntos de conteo con radio fijo de 25m y una distancia entre puntos de 75 m con 10 minutos de observación por punto. Resultados: registramos 548 individuos pertenecientes a 27 familias y 75 especies. Las 4 especies más abundantes fueron: Ramphocelus passerinii, Turdus grayi, Crotophaga sulcirostris y Troglodytes aedon. La riqueza y abundancia puntual fue mayor en pasto natural de alta cobertura vegetal y en bosque ribereño que en cercas vivas y pastos de baja cobertura vegetal. Los hábitats que tuvieron mayor similitud fueron bosque ribereño y cercas vivas, además el 39% de las especies estuvo representada por el gremio insectívoro, seguido por frugívoro con 23%, omnívoro con 17%, carnívoro con 16%, granívoro con 4% y nectarívoro con 1% y cinco de las especies encontradas son dependientes de bosque y seis de ellas indicadoras. Conclusión: finalmente, cabe destacar que las áreas con mayor cobertura vegetal, disponibilidad de alimento y zonas de refugio fueron las que tuvieron mayor cantidad de especies y los sitios de mayor similitud están determinados por la conectividad entre los mismos.Universidad Estatal a Distancia, Costa Rica2019-02-26info:eu-repo/semantics/publishedVersionartículo originalhttp://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/articleapplication/pdftext/htmlapplication/epub+ziphttps://revistas.uned.ac.cr/index.php/cuadernos/article/view/217710.22458/urj.v11i2.2177UNED Research Journal; Vol. 11 No. 2 (2019); 154-161UNED Research Journal; Vol. 11 Núm. 2 (2019); 154-1611659-441X1659-4266reponame:Portal de Revistas UNEDinstname:Universidad Estatal a Distanciainstacron:UNEDspahttps://revistas.uned.ac.cr/index.php/cuadernos/article/view/2177/3029https://revistas.uned.ac.cr/index.php/cuadernos/article/view/2177/3080https://revistas.uned.ac.cr/index.php/cuadernos/article/view/2177/3081Derechos de autor 2019 Cuadernos de Investigación UNEDacceso abiertohttp://purl.org/coar/access_right/c_abf2info:eu-repo/semantics/openAccess2022-09-01T20:20:26Zoai:revistas.investiga.uned.ac.cr:article/2177Universidadhttp://www.uned.ac.crhttps://revistas.uned.ac.cr/index.php/index/oaissegura@uned.ac.crCosta RicaNo aplicaNo aplicaNo aplicaopendoar:02025-06-01T10:59:51.582Portal de Revistas UNED - Universidad Estatal a Distanciafalse |
