Lipid metabolites index habitat quality for Canvasbacks on stopover areas during spring migration

Bouton, Andrew F; Anteau, Michael J; Smith, Eric J; Hagy, Heath M; Lancaster, Joseph D; Jacques, Christopher N

2023 The Condor

doi:10.1093/ornithapp/duad058

Nutrients acquired by ducks on spring migratory stopover areas influence survival and subsequent reproduction. Accordingly, wetland loss and degradation on stopover areas can lead to reduced refueling efficiency and have demographic consequences. Lipid metabolite concentrations in blood provide a...

Avoidance of offshore wind farms by Sandwich Terns increases with turbine density

van Bemmelen, Rob S A; Leemans, Jacco J; Collier, Mark P; Green, Ros M W; Middelveld, Robert P; Thaxter, Chris B; Fijn, Ruben C

2023 The Condor

doi:10.1093/ornithapp/duad055

The expanding use of wind farms as a source of renewable energy can impact bird populations due to collisions and other factors. Globally, seabirds are one of the avian taxonomic groups most threatened by anthropogenic disturbance; adequately assessing the potential impact of offshore wind farms...

Breeders’ age, nest-site characteristics and climatic conditions but not density-dependent effects determine Bonelli’s Eagle breeding performance: A long-term study (2002–2021)

López-Peinado, Andrés; López-López, Pascual

2023 The Condor

doi:10.1093/ornithapp/duad048

The conservation of endangered species is a crucial topic in conservation biology due to the important ecological roles these species play in their respective ecosystems. Top predators are particularly vulnerable to the variation in environmental conditions. The Bonelli’s Eagle (Aquila fasciata)...

Characterizing juvenile dispersal dynamics of invasive Barred Owls: Implications for management

Watson, Whitney A; Hofstadter, Daniel F; Jones, Gavin M; Kramer, H Anu; Kryshak, Nicholas F; Zulla, Ceeanna J; Whitmore, Sheila A; O’Rourke, Virginia; Keane, John J; Gutiérrez, R J; Peery, M Zachariah

2023 The Condor

doi:10.1093/ornithapp/duad061

Characterizing natal dispersal can help manage the spread of invasive species expanding their ranges in response to land use and climate change. The Barred Owl (Strix varia) is a prominent example of an apex predator undergoing a rapid range expansion, having spread from eastern to western North...

Journal Article

Experimental reduction of a primary nest predator fails to decrease nest predation rates of sagebrush songbirds

Rhea, Ashleigh M; Chalfoun, Anna D

2023 The Condor

doi:10.1093/ornithapp/duad049

Predator removal comprises one management strategy to increase the reproductive success of a prey species of concern, particularly within human-altered landscapes. The efficacy of such an approach, however, depends partly on the extent to which predation risk is additive or compensatory, which...

Journal Article

Spatially explicit Bayesian hierarchical models improve estimates of avian population status and trends

Smith, Adam C; D. Binley, Allison; Daly, Lindsay; Edwards, Brandon P M; Ethier, Danielle; Frei, Barbara; Iles, David; Meehan, Timothy D; Michel, Nicole L; Smith, Paul A

2023 The Condor

doi:10.1093/ornithapp/duad056

Population trend estimates form the core of avian conservation assessments in North America and indicate important changes in the state of the natural world. The models used to estimate these trends would be more efficient and informative for conservation if they explicitly considered the spatial...

Beach recreationists perceive a lack of knowledge about shorebirds’ needs as a constraint to walking around shorebird flocks

Comber, Carolyn A; Dayer, Ashley A

2023 The Condor

doi:10.1093/ornithapp/duad050

Walking through shorebird flocks can have negative impacts on shorebird populations. Understanding human behavior is essential for minimizing disturbance. As such, we used a mixed methods approach consisting of phone interviews and a survey to explore (1) recreationists’ perceived benefits and...

Journal Article

Natal forest fragment size does not predict fledgling, pre-migration or apparent annual survival in Wood Thrushes

Hayes, Sue M; Boyd, Brendan P; Israel, Alexandra M; Stutchbury, Bridget J M

2023 The Condor

doi:10.1093/ornithapp/duad054

Determining the drivers and mechanisms for first year survival of migratory songbirds has been an understudied area in population dynamics due to the difficulty in tracking juveniles once they have dispersed from the natal site. With the advancement in miniaturization of radio-tags (battery life...

Historical racial redlining and contemporary patterns of income inequality negatively affect birds, their habitat, and people in Los Angeles, California

Wood, Eric M; Esaian, Sevan; Benitez, Christian; Ethington, Philip J; Longcore, Travis; Pomara, Lars Y

2023 The Condor

doi:10.1093/ornithapp/duad044

The Home Owners’ Loan Corporation (HOLC) was a U.S. government-sponsored program initiated in the 1930s to evaluate mortgage lending risk. The program resulted in hand-drawn “security risk” maps intended to grade sections of cities where investment should be focused (greenlined areas) or limited...

Journal Article

Predator exclosures increase nest success but reduce adult survival and increase dispersal distance of Piping Plovers, indicating exclosures should be used with caution

Stantial, Michelle L; Cohen, Jonathan B; Darrah, Abigail J; Maslo, Brooke

2023 The Condor

doi:10.1093/ornithapp/duad047

Diagnosing unsuccessful population outcomes for endangered species requires understanding relationships among vital rates, ecological conditions, and management variables, including unintended consequences of management actions. The federally threatened Piping Plover (Charadrius melodus) has...
