Setophaga Petechia

Ecological traps arise when anthropogenic change creates habitat that appears suitable but when selected reduces the fitness of an individual. We evaluated whether riparian habitat within the drawdown zone of the Arrow Lakes Reservoir, British Columbia, creates an ecological trap for Yellow Warblers ( Setophaga petechia (L., 1766)) by investigating habitat preferences and the fitness consequences of habitat selection decisions. Preferences were inferred by examining how habitat variables influenced settlement order, and comparing habitat at nest sites and random locations. Males preferred to settle in territories with more riparian shrub and tree cover, higher shrub diversity, and less high canopy cover. Females built nests in taller shrubs surrounded by a greater density of shrub stems. Habitat preferences were positively associated with fitness: nest sites in taller shrubs surrounded by higher shrub-stem densities were more likely to avoid predation and fledge young, whereas territories with more riparian cover, higher shrub diversity, and less high canopy cover had higher annual productivity. We therefore found no evidence that riparian habitat affected by reservoir operations functions as an ecological trap. Current habitat selection decisions may be associated with fitness because Yellow Warblers are adapted to breeding in a heterogeneous environment subject to periodic flooding.

Setophaga Petechia

Con la excepción de unas pocas ciudades grandes, hay poco conocimiento sobre las aves urbanas de América Latina. Utilicé transectos lineales en 15 parques urbanos en la ciudad de San José entre setiembre y diciembre de 2009 y encontré 40 especies, la mayoría Tyrannidae (n=10) y Parulidae (n=9). Hubo 23 residentes (principalmente Tyrannidae), 15 migrantes del norte (en su mayoría Parulidae) y un migrante del sur. Las especies más representativas fueron Contopus sp. y Setophaga petechia. Zenaida asiatica, Turdus grayi y Quiscalus mexicanus estaban muy extendidos, al igual que la paloma Columba livia, que podía llegar a 122 individuos por parque. La diversidad y la abundancia fueron determinadas por el tamaño del parque, la complejidad de la vegetación y la proximidad a los fragmentos de vegetación. Los parques urbanos están siendo utilizados como áreas transitorias y permanentes por las aves migratorias y las características biofísicas de algunos parques favorecen a Columba livia y Quiscalus mexicanus, generando competencia, depredación y desplazamiento de otra especie, así como daños a la infraestructura. Estas áreas verdes podrían usarse para la observación y educación de aves.
