Desert crossing strategies of migrant songbirds vary between and within species

Scientific Reports, 2019
Each year, billions of songbirds cross large ecological barriers during their migration. Understanding how they perform this incredible task is crucial to predict how global change may threaten the safety of such journeys.

Determinants of spring migration departure dates in a New World sparrow: Weather variables reign supreme

Ecology and Evolution
Numerous factors influence the timing of spring migration in birds, yet the relative importance of intrinsic and extrinsic variables on migration initiation remains unclear.

Territoriality and site fidelity of an island endemic subspecies, the Bermuda White-eyed Vireo ( Vireo griseus bermudianus )

Journal of Field Ornithology
Territories are areas that contain resources and are occupied by animals that defend these areas from conspecifics and heterospecifics. Territoriality in birds, which use vocal displays to repel intruders from their territories, has been thoroughly ...

Dynamic evolutionary history and gene content of sex chromosomes across diverse songbirds

Nature Ecology & Evolution, 2018
Songbirds have a species number close to that of mammals and are classic models for studying speciation and sexual selection. Sex chromosomes are hotspots of both processes, yet their evolutionary history in songbirds remains unclear.

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

Biological Reviews, EarlyView.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

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,

Volitional control of vocalizations in corvid songbirds

PLoS Biology, 2019
Songbirds are renowned for their acoustically elaborate songs. However, it is unclear whether songbirds can cognitively control their vocal output. Here, we show that crows, songbirds of the corvid family, can be trained to exert control over their ...

Songbird organotypic culture as an in vitro model for interrogating sparse sequencing networks [PDF]

, 2017
Sparse sequences of neuronal activity are fundamental features of neural circuit computation; however, the underlying homeostatic mechanisms remain poorly understood. To approach these questions, we have developed a method for cellular-resolution imaging

Studying interspecific population synchrony: current status and future perspectives

Ecography, EarlyView.
Interspecific population synchrony, or co‐fluctuations in the population dynamics and demographic parameters of different species, is an important ecological phenomenon with major implications for the stability of communities and ecosystems. It is also central in the context of biodiversity loss, as interspecific synchrony can influence how ecological ...

Finding the beat: From socially coordinated vocalizations in songbirds to rhythmic entrainment in humans.

Frontiers in Human Neuroscience, 2016
Humans and oscine songbirds share the rare capacity for vocal learning. Songbirds have the ability to acquire songs and calls of various rhythms through imitation. In several species, birds can even coordinate the timing of their vocalizations with other
