    Description

    We examined nest sites of Kentucky Warblers (Oporornis formosus) in bottomland hardwood forests in the Coastal Plain of South Carolina to determine habitat features that might affect nesting success. We measured habitat features at 28 nests and at 28 non-use sites during the breeding seasons of 1993 and 1994. All nests were located on the ground and were supported by the bases of herbs and woody seedlings. Concealment of Kentucky Warbler nests was greater from the sides and from above than that of non-use sites. Nest patches were situated in tree-fall gaps; canopy coverage of nest patches was less than that of non-use patches, and tree stem density in nest patches was lower than in non-use patches. Understory vegetation was denser in nest patches than in non-use patches, particularly at nest level (0.0-0.5 m). Successful Kentucky Warbler nests (n = 19) did not differ from unsuccessful nests (n = 8) in any of the variables sampled. Nesting success of Kentucky Warblers may not be influenced strongly by vegetation at the nest site. /// Examinamos las áreas de anidaje de Oporornis formosus en los bosques bajos de angiospermas madereras de los planos costeras de Carolina del Sur para determinar características del hábitat que pueden determinar el éxito al anidar. Medimos las características del hábitat de 28 nidos y 28 lugares no usados durante las épocas reproductivas del 1993 y 1994. Todos los nidos se hallaron en el suelo y se sostenían por bases de hierbas y plántulas madereras. El encubrimiento de los nidos de esta especie era mayor por los lados y desde arriba que en las áreas no utilizadas. Parchos de nidos se situaron en áreas abiertas por caidas de árboles; la cubierta del dosel en los parchos de nidos fué inferior que en los parchos no usados, y la densidad de tallos en los parchos de nidos fué menor que en los parchos no usados. La vegetación del sotobosque fué más densa en parchos de nidos que en los parchos no usados, particularmente a nivel del nido (0.0-0.5 m). Nidos exitosos de esta especie (n = 19) no difirieron de nidos no exitosos (n = 8) en ninguna de las variables muestreadas. El éxito de anidaje de Oporornis formosus puede no estar fuertemente influenciado por la vegetación en la localidad del nido.
