“…Esto ha permi?do que diferentes ins?tuciones promuevan los cer?ficados en este ?po de cul?vo como una alterna?va de conservación de las aves migratorias (Mas & Dietsch 2004), pero la aplicación a cer?ficaciones presenta dificultades y desventajas por sus rigurosos criterios (Philpo( & Dietsch 2003, Mas & Dietsch 2004. Además, las cer?ficaciones podrían incen?var la transformación de bosques de pino o pino-encino (Rappole et al 2003), que también son de importancia para algunas especies migratorias como Setophaga chrysoparia (Rappole et al 2000, King et al 2008 y Vermivora chrysoptera (Benne( 2013). Finalmente, Bailey & King (2019) determinaron que la persistencia del si?o y la supervivencia de Hylocichla mustelina, una especie migratoria, fue menor en el café sombra, a pesar de que su abundancia fue mayor en el café sombra en comparación al bosque na?vo.…”

Honduras cuenta con 349,510 hectáreas cultivadas con café Coffea arabica, que son en su mayoría cultivos tradicionales (café sombra y café sol), y en menor escala cultivos con sistema Dosel Abierto Integrado (DAI). El sistema de café DAI consiste en plantaciones de café rodeadas por bosque en una proporción ≥ 1:1, lo que permite la preservación y la restauración de ecosistemas nativos. El objetivo de nuestra investigación fue evaluar el sistema DAI en cultivos de café como una alternativa de conservación para las aves migratorias neártico-neotropicales y aves residentes. Evaluamos características ecológicas, como la riqueza y abundancia de especies, entre los meses de noviembre de 2018 a abril de 2019. Establecimos 75 puntos de conteo de radio fijo en una zona cafetalera del departamento de Yoro, Honduras. Estadísticamente no registramos diferencias significativas en la riqueza de aves migratorias entre los sistemas de bosque, café DAI y cultivos de café tradicionales. Sin embargo, la riqueza de especies dependientes de bosque fue mayor en los sistema bosque y cultivos de café DAI que en cultivos tradicionales. Además, algunas especies dependientes de bosque, como Myioborus miniatus y Mionectes oleagineus, fueron más abundantes (P < 0.05) en bosque y cultivos de café DAI que en cultivos de café tradicionales. Nuestros resultados se suman a los reportados en Costa Rica, en donde se introdujo este agroecosistema de cultivo de café, en los que se indica que el café DAI puede ser una alternativa para la conservación de aves migratorias y residentes, en particular para especies dependientes de bosque.

“…There were 12 occupancy variables derived from the field measurements and 4 variables from the geographic information system cover type analysis. We included quadratic terms for basal area and other variables that appeared to exhibit a non‐linear relationship because it seemed reasonable that the occupancy of whip‐poor‐wills would be lowest at extreme values, as observed for other bird species in relation to basal area (King et al 2012) or shrubland birds and vegetation succession (Schlossberg and King 2009). Detection variables included observer, ordinal date, year, time (min.…”

Populations of the eastern whip‐poor‐will (Antrostomus vociferus; whip‐poor‐will) have declined throughout most of its range, making it a species of high conservation concern in nearly every state and province where it occurs. Researchers have reported whip‐poor‐wills are associated with forest stands with open canopies, and thus silviculture may be a promising means for promoting their populations, yet the ecological literature does not quantify fine‐scale habitat relationships capable of assisting with silviculture prescriptions. Our objective was to quantify the associations between whip‐poor‐wills, canopy openness, and other vegetation characteristics to provide managers with guidance for whip‐poor‐will management. Based on prior research, we hypothesized that whip‐poor‐wills may be associated with intermediate levels of canopy retention and that their numbers would also be affected by understory characteristics. We surveyed whip‐poor‐wills with point counts in managed forest at the Fort Drum Army installation in New York, USA, during 2015 and 2016 and collected vegetation measurements at each point count location to relate whip‐poor‐will occupancy with vegetation structure and composition. Whip‐poor‐will occupancy was strongly related to intermediate levels of basal area, with peak occupancy at 13.8 m2/ha, a value that corresponds to forest denser than most shrublands but more open than closed‐canopy forest. Whip‐poor‐will presence was negatively related to understory height, which is consistent with prior studies. These findings provide managers with quantitative targets that can be used to increase or maintain whip‐poor‐will numbers and abundance of other disturbance‐associated species similarly unable to persist in unmanaged forests stands. © 2021 The Wildlife Society.

“…Directional (e), Non-directional (xe), Loop (l) and Circumglobal (c)Directional migrants use the same route in their outward and inward migrations, and we include in this group routes of any shape, as long as they are mostly the same both ways. Examples comprise migrations in the shape of an arch of several landbirds between Latin America and the east coast of the United States, including the Golden-cheeked warbler Setophaga chrysoparia(del Hoyo et al 1992(del Hoyo et al -2013King et al 2012).…”

Birds perform many types of migratory movements that vary remarkably both geographically and between taxa. Nevertheless, nomenclature and definitions of avian migrations are often not used consistently in the published literature, and the amount of information available varies widely between taxa. Although comprehensive global lists of migrants exist, these data oversimplify the breadth of types of avian movements, as Publications included in this thesis No publications included.
