Torpor‐assisted migration: Regular use of shallow torpor reduces rest‐phase energy expenditure for songbirds during migration

Journal of Animal Ecology, EarlyView.
Migrating songbirds regularly use shallow torpor (up to 98% of birds for some species) to save energy (up to 42%) during inactive periods. This Ruby‐crowned Kinglet Corthylio calendula that was captured after a spring snowstorm highlights the value of being able to save energy when encountering unfavourable conditions.

The Complete Genome of a Songbird

Abstract Bird genomes are the smallest among amniotes, but remain challenging to assemble due to their structural complexity. This study presents the first fully phased, diploid, telomere-to-telomere (T2T) reference genome for the zebra finch ( Taeniopygia guttata ), a model ...

The collective application of shorebird tracking data to conservation

Conservation Biology, EarlyView.
Abstract 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 declines, we developed a partnership

Structural effects of reedbed grazing and its cessation on reed-nesting songbird densities

Avian Research
Reedbeds are crucial breeding habitats for vulnerable songbird species. Irrespective of their protection status, these habitats may be threatened by organic matter accumulation, progressively leading to structural homogenization and habitat succession ...

Prevalence of traded bird species in key biodiversity areas

Conservation Biology, EarlyView.
Abstract The use and trade of biodiversity involve tens of thousands of species that are exploited at a range of scales, intensities, and degrees of sustainability. As a result, some are highly threatened. Key biodiversity areas (KBAs) are sites of significance for the persistence of biodiversity identified nationally based on standardized criteria ...

The link between colorfulness and extinction risk across the world's passerine birds

Conservation Biology, EarlyView.
Abstract Many of the functional traits that mediate extinction risk across the range of biodiversity relate indirectly to a species’ ability to persist in a changing world, yet certain traits such as coloration directly affect human interactions with wildlife.

CITES Appendix III: An underused tool for international wildlife trade regulation

Conservation Science and Practice, EarlyView.
Appendix III of CITES allows Parties to unilaterally extend domestic species protections to international trade, yet it remains vastly underused, covering just 1.3% of listed species. Drawing on the complete historical record since 1975, we show that Appendix III is most effective for endemic species and functions as a highly successful staging ...

Time‐stressed Bar‐tailed Godwits exploit novel prey during migratory fuelling

Ibis, EarlyView.
Long‐distance migratory birds breeding in the Arctic face challenges as earlier snowmelt shifts the timing of vital resources. To keep up with these advancements, birds will need to modify their migration. Higher fuelling rates during stopover have been identified as a critical mechanism for accelerating migration, but this requires adequate food ...

Projected responses of North American grassland songbirds to climate change and habitat availability at their northern range limits in Alberta, Canada

Avian Conservation and Ecology, 2016
Across North America, grassland songbirds have undergone steep population declines over recent decades, commonly attributed to agricultural intensification.
