A Genomic Catalog of Migratory Microbiomes from Wild Birds across China's Habitats

Advanced Science, EarlyView.
ABSTRACT Migratory birds play an important role in the spread of antimicrobial resistance (AMR); however, gaps in surveillance data from vital regions along migratory flyways across China limit the detection of emergent threats. Here, we assembled 340 metagenomes from 52 bird species covering 11 provincial administrative districts in China, presenting ...

Autumn Migration of Mississippi Flyway Mallards as Determined by Satellite Telemetry [PDF]

, 2012
We used satellite telemetry to study autumn migration timing, routes, stopover duration, and final destinations of mallards Anas platyrhynchos captured the previous spring in Arkansas from 2004 to 2007.

Autumn migration strategy of juvenile great reed warblers Acrocephalus arundinaceus on the eastern European flyway: a spatiotemporal pattern of accumulation and utilisation of energy stores

The European Zoological Journal, 2020
The great reed warbler Acrocephalus arundinaceus is a common migrant through the Western Palearctic. However, its migration strategy, especially the spatiotemporal pattern of accumulation and utilisation of energy stores en route, is poorly known.

Two subspecies of a songbird migrant optimise departure from a coastal stopover with regard to weather and the route lying ahead

Journal of Avian Biology, 2023
Songbirds on migration spend a greater share of their travelling time at stopover sites in order to rest, recover and refuel compared to actively flying.

Stopover Decisions under Wind Influence

Journal of Avian Biology, 1998
Despite evidence that wind conditions are an important factor in determining stopover decisions, models of time-minimizing bird migration have up to now emphasized the optimal response of the migrants to variations in fuel acquisition rates. We present a simple model of a time-minimizing migrant faced with two potential wind conditions on each day ...

‘I Don't Babysit’: Stay‐at‐Home Dads' Perspectives and Experiences Within Australian Society

Australian Journal of Social Issues, EarlyView.
ABSTRACT Stay‐at‐home‐dads are an emerging group in Australia, impacted by societal assumptions and expectations. However, there is a scarcity of research on the perspectives and experiences of fathers assuming stay‐at‐home dad roles within Australian society.

Foraging Behavior of Swainson\u27s Thrushes (Catharus ustulatus) During Spring Migration through Arkansas [PDF]

, 2015
Foraging behavior of Swainson’s Thrushes on spring migration was studied in western Arkansas in the spring of 2013 and 2014. Observations were made in two forested field sites, one of them urban and the other suburban.

Arthropod prey and diets of woodland migrants are similar between natural riparian woodlands and anthropogenic woodlots in the northern prairie region

Avian Conservation and Ecology, 2022
Migration is an energetically expensive activity with important links to population dynamics of migratory birds. Identification of high-quality stopover habitat to support migratory refueling is, therefore, important for woodland migrant conservation ...

Linking Weather and Phenology to Stopover Dynamics of a Long-Distance Migrant

Frontiers in Ecology and Evolution, 2020
For many migratory species, migration can represent a significant part of the annual cycle and the strategies used to move between the breeding and non-breeding areas vary considerably. Weather conditions are important during migration, particularly wind

A “demand and supply” approach to monitoring habitat and population changes of migratory birds

Frontiers in Ecology and the Environment, EarlyView.
Habitat loss and degradation threaten thousands of migratory bird species worldwide. Yet, because the distributions of migratory birds change throughout the year, quantifying the impacts of threats and identifying key sites for conservation attention have proved challenging.
