Effects Of Roadside Edge On Nest Predators And Nest Survival Of Asian Tropical Forest Birds, Daphawan Khamcha, Larkin A. Powell, George A. Gale

Creation of roadside forest edges can have indirect effects on forest bird communities, as edges can promote species detrimental to forest-nesting birds such as nest predators. We assessed species-specific rates of nest survival of understory birds, relative abundances of specific nest predators and predator-specific rates of nest predation relative to the distance from roadside forest edge in a dry evergreen forest in northeastern Thailand. During the breeding seasons (FebruaryeAugust) of 2014e2016 we searched for nests along two, 1-km transects which ran perpendicular from the edge of a five-lane highway into the forest interior. To assess nest predator species, video cameras …

Greater prairie-chickens (Tympanuchus cupido pinnatus) are reported to benefit from grasslands created through the Conservation Reserve Program (CRP). Prairie-chicken population size increased noticeably in southeastern Nebraska after >15% of county-level landscapes were converted to CRP grasslands. But, the mechanisms behind the increase in population size are not well understood, and managers and policy makers could benefit from evidence of CRP’s relative contribution to populations of prairie-chickens. Therefore, our objectives were to characterize the relations of vegetation structure and composition with prairie-chicken nest-site selection and nest survival rates at both the macrohabitat (within landscape of study site) and microhabitat …
Attendance Patterns And Survival Of Western Meadowlark Nests, Larkin A. Powell, Matthew D. Giovanni, Scott R. Groepper, Mitchell Reineke, Walter H. Schacht
Attendance Patterns And Survival Of Western Meadowlark Nests, Larkin A. Powell, Matthew D. Giovanni, Scott R. Groepper, Mitchell Reineke, Walter H. Schacht

Biologists have linked nest attendance and nestling feeding rates to nest predation risk. Patterns of nest attendance also influence the success of methods designed to find nests for research use, such as rope drags. Very little has been published with regard to variation of attendance during the nesting period, but advances in video nest monitoring allow continuous data collection to provide this information. Our objectives were to (1) document attendance patterns at Western Meadowlark (Stumella neglecta) nests, (2) identify predator species of meadowlark nests, and (3) assess the effects of our camera system on nest survival. We used a solar-powered, …
Nest Survival Of Long-Billed Curlew In Nebraska, Cory J. Gregory, Stephen J. Dinsmore, Larkin A. Powell, Joel G. Jorgensen
Nest Survival Of Long-Billed Curlew In Nebraska, Cory J. Gregory, Stephen J. Dinsmore, Larkin A. Powell, Joel G. Jorgensen

Long-billed Curlew Numenius americanus is an imperiled shorebird of western North America. Populations have declined dramatically in the last 150 years from the conversion of prairie to agriculture and it is now listed as a “Tier I at-risk” species in Nebraska. We undertook a 3-year project (2008–2010) to study the nest survival of Long-billed Curlews in Nebraska. We measured vegetation characteristics at each nest site (n = 14 nests) on two different spatial scales and used program MARK to model nest survival as a function of multiple covariates. Apparent nest survival was 29% (n = 4 successful nests) and our …
The Influence Of Habitat And Environment On Smallmouth Bass (Micropterus Dolomieu) Nest Sites And Nest Success In Northern Lake Michigan, Mark A. Kaemingk, Alexander Clem, Tracy L. Galarowicz
The Influence Of Habitat And Environment On Smallmouth Bass (Micropterus Dolomieu) Nest Sites And Nest Success In Northern Lake Michigan, Mark A. Kaemingk, Alexander Clem, Tracy L. Galarowicz

Information on smallmouth bass nesting ecology is lacking in northern Lake Michigan, despite available information for other Great Lakes ecosystems. Our objectives were to identify factors that influenced nesting sites and nest success in a smallmouth bass population in northern Lake Michigan. Temperature, substrate firmness, and lake bottom rugosity were measured and related to the number of smallmouth bass nests in four bays. We also investigated the role of temperature, effective fetch, and storms to explain nest success. Temperature appeared to be most important in explaining the number of nests and nest success; transects that experienced the greatest number of …

We used traditional searching, as well as radio-telemetry, to find 125 Wood Thrush (Hylocichla mustelina) 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, …
