Experimental inhibition of a key cellular antioxidant affects vocal communication [PDF]

open access: yes, 2017
1. There is substantial interest of evolutionary ecologists in the proximate mechanisms that modulate vocal communication. In recent times, there has been growing interest in the role of oxidative stress as a mediator of avian song expression. 2.

Risk of Secondary Extinction in the Asian Songbird Trade, as Exemplified by the Selling of Crested Jayshrikes as Master Birds

open access: yesIntegrative Conservation, EarlyView.
The Asian Songbird Crises negatively affects so‐called master birds, species that are used to increase the song complexity of competitive songbirds. We assessed the trade in a master bird, the crested jayshrike, in Indonesia before and after its legal protection.

Unsupervised discovery of temporal sequences in high-dimensional datasets, with applications to neuroscience. [PDF]

open access: yes, 2019
Identifying low-dimensional features that describe large-scale neural recordings is a major challenge in neuroscience. Repeated temporal patterns (sequences) are thought to be a salient feature of neural dynamics, but are not succinctly captured by ...

From dusk till dawn: ecoacoustic monitoring reveals wind energy impacts on roding Eurasian woodcock Scolopax rusticola

open access: yesWildlife Biology, EarlyView.
Renewable energy is vital for reducing carbon emissions and yet its infrastructure poses challenges to biodiversity. While the impacts of wind power on bats and raptors are well‐studied, the effects on elusive species remain largely unknown. The Eurasian woodcock Scolopax rusticola, a nocturnal forest bird, performs characteristic courtship flights at ...

Development of optimized methods for unbiased dusky grouse population monitoring using real and simulated data

open access: yesWildlife Biology, EarlyView.
Rigorous state‐wide monitoring programs are lacking for dusky grouse Dendragapus obscurus, a North American species of forest grouse with relatively low detectability that is found in coniferous and mountainous areas in the western United States and Canada.

A comprehensive account of sound sequence imitation in the songbird.

open access: yesFrontiers in Computational Neuroscience, 2016
The amazing imitation capabilities of songbirds show that they can memorize sensory sequences and transform them into motor activities which in turn generate the original sound sequences.

Parallels in the sequential organization of birdsong and human speech. [PDF]

open access: yes, 2019
Human speech possesses a rich hierarchical structure that allows for meaning to be altered by words spaced far apart in time. Conversely, the sequential structure of nonhuman communication is thought to follow non-hierarchical Markovian dynamics ...

DNA metabarcoding reveals wolf dietary patterns in the northern Alps and Jura Mountains

open access: yesWildlife Biology, EarlyView.
Understanding predator–prey interactions is crucial for wildlife management and human–wildlife coexistence, particularly in multi‐use landscapes such as western Europe. As wolves Canis lupus recolonize their former habitats, knowledge of their diet is essential for conservation, management and public acceptance.

Nocturnal Songbird Migration [PDF]

open access: yesNature, 1971
WE would like to comment on Evans's criticisms1 of our recent article2 concerning the influence of wind on the direction of nocturnal songbird migration. We pointed out that problems in identifying bird types from radar echoes may have contributed to the controversy about passerine nocturnal migrants compensating for wind drift. Evans claims that there

Deer reduce habitat quality for a woodland songbird: evidence from settlement patterns, demographic parameters, and body condition. [PDF]

open access: yes, 2013
Understanding avian responses to ungulate-induced habitat modification is important because deer populations are increasing across much of temperate Europe and North America.
