Examining the capability for rhythmic synchronization and music production in vocal learning parrot species

Frontiers in Psychology, 2023
Vocal production learning and beat perception and synchronization (BPS) share some common characteristics, which makes the vocal learning and rhythmic synchronization hypothesis (VLH) a reasonable explanation for the evolution of the capability for ...

Altering Opioid Neuromodulation in the Songbird Basal Ganglia Modulates Vocalizations

Frontiers in Neuroscience, 2019
Although the interplay between endogenous opioids and dopamine (DA) in the basal ganglia (BG) is known to underlie diverse motor functions, few studies exist on their role in modulating speech and vocalization.

Endogenous Programs and Flexibility in Bird Migration

Frontiers in Ecology and Evolution, 2020
Endogenous programs that regulate annual cycles have been shown for many taxa, including protists, arthropods, fish, mammals and birds. In migration biology, these programs are best known in songbirds.

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 ...

Detection of Babesia odocoilei in Ixodes scapularis Ticks Collected from Songbirds in Ontario and Quebec, Canada

Pathogens, 2020
Songbirds widely disperse ticks that carry a diversity of pathogens, some of which are pathogenic to humans. Among ticks commonly removed from songbirds, the blacklegged tick, Ixodes scapularis, can harbor any combination of nine zoonotic pathogens ...

Bison Reintroduction to Mixed-Grass Prairie Is Associated With Increases in Bird Diversity and Cervid Occupancy in Riparian Areas

Frontiers in Ecology and Evolution, 2022
In grassland ecosystems, grazing by large herbivores is a highly influential process that affects biodiversity by modifying the vegetative environment through selective consumption.

Utterance evolution: the road to generative, combinatorial communicators

Biological Reviews, EarlyView.
ABSTRACT Language has long been considered uniquely complex in the animal kingdom; however, animal research over the last decade has begun to challenge some long‐standing premises about exactly which language capacities are uniquely human. The task of resolving why and how complex communication systems evolve, particularly human language, has ...
