Anthropogenic Renourishment Feedback on Shorebirds: a Multispecies Bayesian Perspective [PDF]

open access: yes, 2011
In this paper the realized niche of the Snowy Plover (Charadrius alexandrinus), a primarily resident Florida shorebird, is described as a function of the scenopoetic and bionomic variables at the nest-, landscape-, and regional-scale.

Could changes in the agricultural landscape of northeastern China have influenced the long-distance transmission of highly pathogenic avian influenza H5Nx viruses? [PDF]

open access: yes, 2017
In the last few years, several reassortant subtypes of highly pathogenic avian influenza viruses (HPAI H5Nx) have emerged in East Asia. These new viruses, mostly of subtype H5N1, H5N2, H5N6, and H5N8 belonging to clade 2.3.4.4, have been found in several

Seasonal Movements, Migratory Behavior, and Site Fidelity of West Indian Manatees along the Atlantic Coast of the United States as Determined by Radio-telemetry [PDF]

open access: yes, 2000
The study area encompassed the eastern coasts of Florida, Georgia, and South Carolina, including inland waterways such as the St. Johns River (Fig. 1). Manatees inhabited the relatively narrow band of water that lies between the barrier beaches and the

Migration strategy and constraint in migration behavior vary among shorebird species with different life histories

open access: yesEcosphere
Migration strategy is a key behavioral characteristic guiding how migratory species time their annual cycles and use habitat. Understanding variation in migration strategy within and among species and individuals can be useful for understanding how birds

Migratory Birds as Global Dispersal Vectors [PDF]

open access: yes, 2016
Propagule dispersal beyond local scales has been considered rare and unpredictable. However, for many plants, invertebrates, and microbes dispersed by birds, long-distance dispersal (LDD) might be regularly achieved when mediated by migratory movements ...

Protocol to produce diel vertical movement patterns from the BirdScan MR1 vertical-looking biological radar

open access: yesSTAR Protocols
Summary: Vertical-looking radars (VLRs) detect individual flying animals up to ∼2 km above ground and characterize their flight track, timing, wing movement, size, and shape.

Constitutive immune function is not associated with fuel stores in spring migrating passerine birds

open access: yesEcology and Evolution
Migratory birds may either upregulate their immune system during migration as they might encounter novel pathogens or downregulate their immune system as a consequence of trade‐offs with the resource costs of migration.

The physiology and biomechanics of avian flight at high altitude [PDF]

open access: yes, 2006
Many birds fly at high altitude, either during long-distance flights or by virtue of residence in high-elevation habitats. Among the many environmental features that vary systematically with altitude, five have significant consequences for avian flight ...

Migration in the balance:tight ecological margins and the changing fortunes of shorebird populations [PDF]

open access: yes, 2006
Dependent as they are on rare and remote open habitats for breeding and survival, shorebirds connect continents and hemispheres with their individual movements.
