“…Controlling for the landscape context with a block design in different state forests, nesting success of canopy songbirds did not differ between shelterwood and unharvested stands. Similar numbers of diurnal avian predators in both stand types, which were directly documented as nest predators in our system (Newell and Rodewald 2011), could explain absence of any effect of shelterwood harvesting on nest survival. Changes in the predator community in more fragmented landscapes can depress nesting success (Donovan et al 1997, Rodewald and Yahner 2001), although additive effects of partial harvesting to fragmentation appear limited (Eng et al 2011).…”

“…Others have found similar limited or variable short‐term responses of canopy songbirds to partial harvesting (review in Newell 2010). Weak and variable responses suggest other factors such as topography, existing forest structure, or floristics may mediate the response of canopy songbirds to harvesting (Newell and Rodewald 2011). Further work is needed to examine more complex interactions of partial harvesting with other forest attributes.…”

Interest in regenerating oaks (Quercus spp.) has promoted use of partial harvesting techniques that create an open forest structure. From 2007 to 2009, we studied songbirds in mixed‐oak forests in southeastern Ohio, comparing shelterwoods recently harvested to 50% stocking and closed‐canopy mature second‐growth. We surveyed birds using distance‐based methods (56 line transects in 18 stands at 4 forests). We intensively investigated suitability of shelterwoods for canopy‐nesting species by examining habitat preferences, as measured by settlement patterns, age distributions, and site fidelity; we also examined nesting success. Several midstory and ground‐nesting species were 26–73% less abundant in shelterwood than unharvested stands, whereas shrub‐nesting species increased >100% several years post‐harvesting. Canopy‐nesting species were 31–98% more abundant in shelterwoods, but cerulean warbler (Setophaga cerulea) responses varied by forest. Patterns of settlement and site fidelity were generally similar among stands. Proportions of young males were actually greater for several species in shelterwood than unharvested stands, which may have been a consequence of young birds colonizing newly created (or improved) habitat. Even in our predominantly forested study system, nesting success (>700 nests) was low, ranging from 15% to 19% for yellow‐throated vireos (Vireo flavifrons) and cerulean warblers, to 27–36% for scarlet tanagers, blue‐gray gnatcatchers (Polioptila caerulea) and eastern wood‐pewees (Contopus virens). However, nest survival did not differ between shelterwood and unharvested stands, possibly because numbers of avian predators did not change with harvesting. Despite increased numbers of brown‐headed cowbirds (Molothrus ater) in shelterwoods, only 2% of canopy nests in which young could be identified were parasitized. Although these results suggest shelterwood harvests containing abundant overstory trees can provide short‐term breeding habitat for canopy songbirds, long‐term responses of birds to partial harvesting may differ from those documented here depending on different management options employed. Management for oak regeneration will typically remove all overstory trees later in the cutting cycle, initially resulting in loss of nesting substrates and hence breeding habitat for canopy songbirds. © 2011 The Wildlife Society.

“…During the breeding season, we also observed Cerulean Warblers provisioning young at nests in Ohio from 2007 to 2009 (Newell and Rodewald , ). We conducted 30‐min observations of nestling provisioning behavior (51 nests in 39 territories), focusing on the later nestling phase when adults were actively feeding young (>80% of nestlings observed were at least 4 days old based on estimated hatching dates).…”

Three sites had recently been partially harvested to ∼50% stocking (Newell and Rodewald , ).

ABSTRACT. Birds require additional resources for raising young, and the breeding currency hypothesis predicts that insectivorous species exploit large soft-bodied prey during the breeding season, but shift to small, likely hardbodied, prey during the non-breeding season. To test this hypothesis, we examined prey use by Cerulean Warblers (Setophaga cerulea), foliage-gleaning Nearctic-Neotropical migrants, during the breeding and non-breeding seasons. We collected data on foraging behavior during the breeding season (including observations of prey items fed to young) in upland mixed-oak forest in southeastern Ohio in 2009 and 2010 and, during the non-breeding season, in shade coffee in the Cordillera de Merida, Venezuela, in 2008-2009. Cerulean Warblers captured 7% more large prey (visible prey extending beyond the bill) during the breeding than the non-breeding season, but foraged at similar rates during both seasons. Large, soft-bodied prey appeared to be especially important for feeding young. We found that adults delivered large prey on >50% of provisioning visits to nests and 69% of identifiable large prey fed to nestlings were greenish larvae (likely Lepidoptera or caterpillars) that camouflage against leaves where they would tend to be captured by foliage-gleaning birds. Availability of specific taxa appeared to influence tree species foraging preferences. As reported by other researchers, we found that Cerulean Warblers selected trees in the genus Carya for foraging and our examination of caterpillar counts from the central Appalachian Mountains (Butler and Strazanac 2000) showed that caterpillars with greenish coloration, especially Baileya larvae, may be almost twice as abundant on Carya than Quercus. Our results provide evidence for the breeding currency hypothesis, and highlight the importance of caterpillars to a foliage-gleaning migrant warbler of conservation concern.RESUMEN. Comportamiento forrajero del Chipe Cerúleo durante la temporada reproductiva y no reproductiva: evidencia de la hipótesis de divisa de crianza Las aves requieren recursos adicionales a fin de criar a los pichones, y la hipótesis de divisa de crianza predice que las especies insectívoras explotan presas grandes de cuerpo blando durante la temporada reproductiva, pero que cambian a presas pequeñas de cuerpo duro en la temporada no reproductiva. A fin de poner a prueba esta hipótesis, examinamos el uso de presas por parte del Chipe Cerúleo (Setophaga cerulea), forrajeadores de follaje y migrantes Neártico-Neotrópico, durante la temporada reproductiva y no reproductiva. Colectamos datos del comportamiento forrajero durante la temporada reproductiva (incluyendo observaciones de presas entregadas a los pichones) en un bosque de tierras altas compuesto de varias especies de roble en el sur este de Ohio en 2009 y 2010 y, durante la temporada no reproductiva, en una plantación sombreada de café en la Cordillera de Mérida, Venezuela, en [2008][2009].
