“…Thus it is evident that the overstorey makes a significant contribution to species richness and abundance of wintering forest-dwelling migrants, as previously cited by others (Robbins et al 1989, Terborgh 1989, Askins et al 1990. As these authors have noted (and we concur), the continuing conversion of shade coffee to sun coffee will be detrimental to most wintering migrants (and many resident species as well).…”

“…Current concern regarding the fate of Neotropical migrant landbirds arises from studies indicating that some population declines are associated with deforestation on either the North American breeding grounds or on the tropical wintering grounds (reviewed in Askins et al 1990). While recent local declines can mostly be attributed to the negative consequences of forest fragmentation on the breeding grounds (Wilcove and Robinson 1990), the high rate of deforestation in Middle America and the Caribbean (Lanly 1982) is likely to have a greater impact on migrant populations in the future (Rappole and Powell 1986).…”

SummaryWintering Nearctic migrants constitute a high proportion of the birds present in many terrestrial habitats in the Bahamas and Greater Antilles, but their proportions decline southward through the Lesser Antilles. Many migrants winter on densely populated islands which have been extensively deforested. Current estimates show that only 21% of the land area, or approximately five million hectares, remain in forest on Caribbean and Bahamian islands, indicating that most of the major deforestation has already occurred. Although reforestation is under way on a few islands, many remnant forest fragments are threatened by humans or natural disturbances such as drought or hurricanes. Thus wintering migrants requiring closed-canopy forest are at greatest risk to habitat loss, whereas species requiring early successional habitats are not currently threatened, assuming that pesticide use does not increase. Policies which protect forests, particularly mangroves, wet limestone and montane broadleaf forests in the Greater Antilles, and broadleaf scrub ("coppice") in the Bahamas, will be beneficial to migrants and endemic species.Las aves migratorias nearticas invernantes constituyen una alta proporcion de las aves presentes en numerosos habitats terrestres de lasBahamas y de las Antillas Mayores, pero sus proporciones disminuyen hacia el sur a traves de las Antillas Menores. Muchos migrantes invernan en islas densamente pobladas que han sido deforestadas extensivamente. Estimas actuates muestran que solo el 21% del area terrestre, o aproximadamente cinco millones de hectareas, permanecen arboladas en las islas del Caribe y las Bahamas, indicando que la mayor parte de la deforestation ya ha ocurrido. Aun cuando cierta reforestaci6n se esta Uevando a cabo en unas pocas islas, los fragmentos restantes de bosque estan amenazados por el hombre o por disturbios naturales tales como huracanes o sequias. Por lo tanto, las aves migratorias que requieren bosque con un dosel cerrado estan en mayor riesgo de perder su habitat, mientras que las especies que requieren etapas tempranas de sucesion no estan amenazadas en el presente, asumiendo que el uso de pesticidas no aumente. Las politicas publicas que protejan los bosques, particularmente manglares, bosques latifolios montanos y bosques humedos de piedra caliza en las Antillas Mayores, y matorral latifolio ("coppice") en las Bahamas seran beneficiosas para las aves migratorias y residentes por igual.

“…doi:10.1016/j.biocon.2010. 05.025 are disproportionately declining in fragmented forests worldwide, with Neotropical-Nearctic migrants (e.g., Askins et al, 1990;Robbins et al, 1989) and Neotropical residents (e.g., Sigel et al, 2006;Sodhi et al, 2004;Stouffer et al, 2009) particularly impacted. Dispersal limitation is increasingly identified as a dominant mechanism underlying their demise (Lampila et al, 2005;Stratford and Robinson, 2005).…”

“…Substantial population declines have been reported for nearctic-neotropical migrant landbirds over the past four decades, particularly among forestbreeding species (reviewed in Askins et al, 1990). Plausible links have been drawn between these declines and forest fragmentation in North America (with its associated problems of nest predation and parasitism; Terborgh, 1989), as well as the loss of wintering habitat in M6xico, Central and South America (Robbins et al, 1989).…”
