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 ...

Mercury in Zhongar Alatau (Kazakhstan) and Carpathian mountains (Slovakia): songbirds and mice as indicators

Folia Oecologica
Anthropogenic activities have contributed to the increase of heavy metals and to the alteration of their natural cycles in the environment. Mercury (Hg) is now considered to be one of the most toxic elements whose levels need to be monitored in abiogenic

Significant Instances in Motor Gestures of Different Songbird Species

Frontiers in Physics, 2019
The nervous system representation of a motor program is an open problem for most behaviors. In birdsong production, it has been proposed that some special temporal instances, linked to significant aspects of the motor gestures used to generate the song ...

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 ...

Rangeland Songbirds

, 2023
Abstract Songbirds that occur across the diverse types of North American rangelands constitute many families within the Order Passeriformes, and hundreds of species. Most are declining, and many are considered potential indicator species for rangeland ecosystems. We synthesized information on the natural and life history, habitat requirements,

Timing pattern of Common Cuckoo parasitism and its relation to host nest attendance

Ibis, EarlyView.
Classical works show the adaptive importance of precise timing of egg‐laying in brood parasitic Common Cuckoos Cuculus canorus to ensure sufficient incubation time and successful hatching. Laying in the late afternoon has been suggested to increase the chance of secretive parasitism and therefore escape the aggressive mobbing by hosts, yet this ...

Wood Thrush (Hylocichla mustelina) occupancy patterns reveal sensitivity to low precipitation on nonbreeding grounds in northern Costa Rica

Ibis, EarlyView.
Climatic change and anthropogenic disturbances are reshaping animal populations. Habitat loss and extreme climatic events are particularly strong drivers of declines in species that depend on forested areas. For migratory songbirds, climate and the persistence of suitable habitat over time are fundamental to sustaining populations annually.

A systematic review and meta‐analysis of variation in nest predation of ground‐nesting birds

Ibis, EarlyView.
Predation and communities of predators of ground‐nesting bird nests and fledglings have been studied across multiple groups of ground‐nesting birds, such as waders, waterbirds, gamebirds and passerines, and habitats, but differences and similarities between groups are less studied.

Dietary selectivity mediates niche overlap and interspecific competition in a reedbed warbler community in southern Europe

Ibis, EarlyView.
Sympatric species are expected to use resources differently along one or more ecological dimensions. This can be complex when there is partial separation along multiple dimensions, such as where bird species exhibit similarities in habitat use and diet.

Syrinx anatomy and vocalizations in New World vultures (Aves: Cathartidae): Implications for avian vocal evolution

Journal of Anatomy, EarlyView.
New World vultures are the only avian clade proposed to lack a syrinx and have been described as non‐vocal. Using dissection, diceCT, and histology, we demonstrate that cathartid vultures have novel syringeal features that form a syrinx and vocal characterization reveals that they produce more complex vocalizations than previously reported.
