Mimicking the mountains: Using spatial characteristics of unharvested habitat to guide working forest management for a rare, forest-dependent songbird

James P Longo, Amber M. Roth, Junior A. Tremblay, Peter Thomas

Management of the rare Bicknell’s Thrush (Catharus bicknelli) is increasingly a forestry-driven challenge, as most nesting habitat in Canada now occurs within working forest landscapes. This species primarily nests in short, dense red spruce (Picea rubens) and balsam fir (Abies balsamea) forests …

The collective application of shorebird tracking data to conservation

Autumn‐Lynn Harrison, Candace Stenzel, Alexandra M. Anderson, Jessica E. Howell et autres

Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence-based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these …

Multi-phase migration models for Nearctic–Neotropical migrant birds can inform conservation planning

Ryan E Brodie, Nicholas J. Bayly, Ruth E. Bennett, Than J. Boves et autres

Abstract Despite recent avian research describing major migratory pathways and stopover regions, many species-specific migratory pathways and stopover locations remain unidentified and uncharacterized. We selected 4 Nearctic–Neotropical migrant bird species experiencing population declines and for which targeted conservation is limited during migratory …

Seasonal, age‐ and sex‐related differences in the use of external migratory cues by American Woodcock ( Scolopax minor )

Alexander C. Fish, Amber M. Roth, Greg Balkcom, Gary R. Costanzo et autres

Timing of migration is seasonal and tied to changing photoperiod; however, individual birds rely extensively on external environmental cues, such as weather, to assess likely flight conditions and make fine‐scale decisions about migratory departures. Considerable variation may exist among individuals in how …

Apparent annual survival of adult Vermivora chrysoptera (Golden-winged Warbler) does not differ by sex or region

Emily Filiberti, Amber M. Roth, Wayne E. Thogmartin, Ethan J. Royal et autres

Abstract Understanding range-wide demographic, spatial, and temporal variation in annual survival is essential for managing species of conservation concern. Multi-population models are useful tools for integrating diverse datasets, reducing biases, and deriving survival estimates across differing spatial scales. We conducted a range-wide, …

Possibilité que le taux de survie annuel apparent des parulines à ailes dorées (Vermivora chrysoptera) adultes ne diffère pas selon le sexe ou la région

Emily Filiberti, Amber M. Roth, Wayne E. Thogmartin, Ethan J. Royal et autres

We conducted a range-wide, multi-population apparent annual survival analysis for a declining songbird, the golden-winged warbler, using data from 19 sites across its breeding and non-breeding grounds. This species breeds in two disjunct regional populations, the Great Lakes and Appalachian Mountains, which …

Low migratory flight altitudes may explain increased collision risk for Scolopax minor (American Woodcock)

Liam A. Berigan, Sarah J. Clements, Rachel Darling, Alexander C. Fish et autres

Abstract Understanding bird migration at low altitudes is critical to evaluating risk of collision with obstacles. Recent advances in satellite tracking technologies allow quantifying use of low altitudes by small migrating birds with a high level of precision, allowing species-level inference into …

Beyond tracking: Advancing animal ecology through the longitudinal sampling of individuals

Bryant C. Dossman, Emily Filiberti, Amber M. Roth, Peter P. Marra

ABSTRACT Rarely, is there an opportunity to study and directly observe the same migratory animal across both breeding and nonbreeding seasons. In a rare, documented case, we highlight a live reencounter of a female Setophaga ruticilla (American Redstart) on its nest during …

Nonbreeding distributions of four declining Nearctic–Neotropical migrants are predicted to contract under future climate and socioeconomic scenarios

Ryan E Brodie, Nicholas J. Bayly, Ana M. González, Jessica N. Hightower et autres

Abstract Climate and land use/land cover change are expected to influence the stationary nonbreeding distributions of 4 Nearctic–Neotropical migrant bird species experiencing population declines: Cardellina canadensis (Canada Warbler), Setophaga cerulea (Cerulean Warbler), Vermivora chrysoptera (Golden-winged Warbler), and Hylocichla mustelina (Wood Thrush). Understanding …
