J. D. Lang David G. Krementz Michael J. Conroy Larkin A. Powell 2005 <p><span>We used traditional searching, as well as radio-telemetry, to find 125 Wood Thrush (</span><i><span class="genus-species">Hylocichla mustelina</span></i><span>) nests during 1994–1996 at the Piedmont National Wildlife Refuge in Georgia, USA. We compared daily nest survival rates for 66 nests of radio-marked birds with 59 nests of birds found through systematic searching. By using radio-telemetry, we found Wood Thrush nests in higher elevation pine habitats, in addition to the more usual hardwood forests with moist soils. We found nests of radio-marked birds farther from streams than nests found by systematic searching. Thirty-two percent of radio-marked birds' nests were found at the tops of slopes, compared to 15% of the nests found by traditional searching. In addition, radio-marked birds generally moved up-slope for re-nesting attempts. Although the distribution of nests found with telemetry and searching varied, daily nest survival did not vary between the two groups. Radio-telemetry provided new information about Wood Thrush nesting habitats. We believe radio-telemetry can be a valuable addition to traditional searching techniques; it has the potential to provide a sample of nests free from a priori habitat biases.</span></p> application/pdf 10.1648/0273-8570-76.3.274 en Association of Field Ornithologists Use of radio-telemetry to reduce bias in nest searching article
