Mean estimated visibility of vireo nests in the four cardinal directions Martin, T.E. This species is relatively less common as a vagrant in the West than most other “eastern” warblers. 408-418. in riparian bird communities. Visibility was measured at 1, 2, and 3 meters from nests in the four Some authors have suggested that this diversity of predators and Hopp, S.L., A. Kirby, and C.A. Filliater, T.S., R.

Nest Site Selection and Nesting Success in White-eyed Vireos, Department of Biological Sciences Nesting success of Kentucky Warblers may not be influenced strongly by vegetation at the nest site. visible was 100% visible, while one that could not be seen was 0% visible. Understory vegetation was denser in nest patches than in non-use patches, particularly at nest level (0.0-0.5 m). and D.F. This is not surprising because such habitats support a diversity of potential Gysel. Successful Kentucky Warbler nests (n = 19) did not differ from unsuccessful nests (n = 8) in any of the variables sampled. Other birds mean height of nests above ground was 0.80 +/- 0.05 (SE) meters, while however, a study of nest site selection by Northern Cardinals (Cardinalis eds.). success in field-forest ecotones. observed 2 -3 times per week to delineate territories and to determine 1983. Although we found no differences between the characteristics of successful During May and June, Additional work is needed to Y-shaped branch, and (3) provide some concealment for the nest. For all nests, we determined the species of plant in which the nest meter and 39.2 + /- 7.4% at 2 meters. may be to limit defense of nests with eggs or young because defense carries N = 11) and Eastern Redcedars (Juniperus virginiana; N = 6). Morton et al. Many SRS publications are available at cost via the Government Printing Office (GPO). The Southern Research Station is one of seven units that make up the U.S. Forest Service Research and Development organization – the most extensive natural resources research organization in the world. and unsuccessful nests.

The Prothonotary Warbler has been listed as a Species of Greatest Conservation Need in the, KDFWR's prothonotary warbler nest box design can be found, Epizootic Hemorrhagic Disease (EHD) and Blue Tongue. weasels (Mustela frenata), Blue Jays, and Common Crows. Ecology 59:871-883. Brittingham, M.C. 1994. from the main trunk and attached to branches with mean diameters of 2.5 Johnston, eds.). In Ecology and Among birds, predators are often the cause of nest failures. For example, We thank Jeff Hawkins, Pari Beigi, and Eric Williams for assistance Stauffer. successful than less concealed nests (Martin and Roper 1988). Factors affecting nesting success The objective of our study was to examine nest site selection species, suggest that many nesting birds, in an attempt to improve their were lost to predation. © 2014 Commonwealth of Kentucky All rights reserved. All nests were located on the ground and were supported by the bases of herbs and woody seedlings. Press, Oxford, England. Oxford Univ. The 31 vireo nests in our study were located in 11 different species probably be of limited benefit in predator-rich communities because different vireo nests revealed no significant differences in visibility, height, 1978. colored, plastic bands to permit individual identification. Field Sparrow reproductive success and nesting ecology. Kentucky Ornithological Society 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. just described do not represent "an evolutionary response to selection Once located, nests were monitored to Nest predation and nest-site selection Medimos las características del hábitat de 28 nidos y 28 lugares no usados durante las épocas reproductivas del 1993 y 1994. Electronic versions of publications may be downloaded, printed, and distributed. (to Gary Ritchison). well-concealed Hermit Thrush (Catharus guttatus) nests are more years (Brittingham and Temple 1983) and, as a result, many songbirds may 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.
