Lingual articulation in songbirds [PDF]
Lingual articulation in humans is one of the primary means of vocal tract resonance filtering that produces the characteristic vowel formants of speech. In songbirds, the function of the tongue in song has not been thoroughly examined, although recent research has identified the oropharyngeal-esophageal cavity as a resonance filter that is actively ...

Human infections associated with wild birds. [PDF]
IntroductionWild birds and especially migratory species can become long-distance vectors for a wide range of microorganisms. The objective of the current paper is to summarize available literature on pathogens causing human disease that have been ...

Evolution of female promiscuity in Passerides songbirds
Female promiscuity is highly variable among birds, and particularly among songbirds. Comparative work has identified several patterns of covariation with social, sexual, ecological and life history traits.

Managed forests contribute to both economic and non-timber values, but the ecological role of managed, including planted, forests to biodiversity objectives at the landscape scale needs to be better understood.

(Micro)evolutionary changes and the evolutionary potential of bird migration
Seasonal migration is the yearly long-distance movement of individuals between their breeding and wintering grounds. Individuals from nearly every animal group exhibit this behavior, but probably the most iconic migration is carried out by birds, from ...

Involvement of the cortico-basal ganglia-thalamocortical loop in developmental stuttering [PDF]
Stuttering is a complex neurodevelopmental disorder that has to date eluded a clear explication of its pathophysiological bases. In this review, we utilize the Directions Into Velocities of Articulators (DIVA) neurocomputational modeling framework to ...

Birds That Don't Exist: Niche Pre-Emption as a Constraint on Morphological Evolution in the Passeroidea. [PDF]
We use topological data analysis to reveal a persistent morphological gap in a major group of songbirds (superfamily Passeroidea). The gap remained unoccupied for millions of years, even though nearby morphologies are common and the same body form exists in other groups of birds.

The direct response of the gonads to cues of stress in a temperate songbird species is season-dependent. [PDF]
The gonadotropin releasing hormone (GnRH) system in the hypothalamus is often considered the final point in integration of environmental cues as they pertain to the reproductive axis.

Migratory connectivity and barrier-crossing flights of Vermivora warblers are associated with synoptic weather conditions. [PDF]
Tracking data from ~10 g songbirds illuminate how weather conditions affect the initiation of long‐distance migratory flights across the Gulf of Mexico during autumn and spring. Seasonal differences and weak migratory connectivity near the Gulf suggest adaptive responses to weather, with future climate trends potentially reducing crossing favorability ...
