Stopover ecology of autumn-migrating Bluethroats (Luscinia svecica) in a highly anthropogenic river basin [PDF]

Journal of Ornithology, 2019
Wetlands are highly productive habitats used by many avian species as stopover sites during their migrations. However, these habitats are highly threatened by anthropogenic activities, such as land-use changes, the introduction of exotic species, and global warming. Further understanding on the spatiotemporal use of wetlands and their surrounding areas

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.

Using programmable infusion pump in avian species – a validation methodology in geese

Wildlife Biology, EarlyView.
Wildlife face anthropogenic and natural stressors that affect their physiology and behaviour. The activity of the hypothalamic–pituitary–adrenal axis and glucocorticoid (GC) production is intrinsically linked with energy regulation and environmental stressors.

Tracking data reveal high spatiotemporal consistency in migration of the threatened Taiga Bean Goose (Anser fabalis middendorffii) along the East Asian-Australasian flyway

Global Ecology and Conservation
Migration consistency, the tendency of migratory birds to repeatedly use familiar breeding, stopover and wintering sites across years and seasons while maintaining a stable migration schedule, is advantageous as it minimizes the time and energy required ...

Diet, phenology and body size shape nutrient release by songbirds

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Animals can dramatically alter ecosystem structure and function through the cycling and transport of nutrients in their waste. While birds are particularly capable of influencing nutrient cycles due to their high mobility, abundance, metabolism and functional diversity,

The State of Migratory Landbirds in the East Asian Flyway: Distributions, Threats, and Conservation Needs

Frontiers in Ecology and Evolution, 2021
With nearly 400 migratory landbird species, the East Asian Flyway is the most diverse of the world’s flyways. This diversity is a consequence of the varied ecological niches provided by biomes ranging from broadleaf forests to arctic tundra and ...

Unraveling Occurrence Patterns and Diversity of Avian Malaria Parasites in Iberian Obligate and Facultative Scavenger Birds

Integrative Zoology, EarlyView.
Low overall haemosporidian occurrence (3.4%; 13/383). Unexpected high lineage diversity (10 new host–parasite interactions). Novel Leucocytozoon lineage (GYPBAR01) in all European vultures except the griffon vulture. Plasmodium relictum (lineage SGS1) in adult red kites.

Winter connectivity and leapfrog migration in a migratory passerine

Ecology and Evolution, 2023
Technological advances in migratory tracking tools have revealed a remarkable diversity in migratory patterns. One such pattern is leapfrog migration, where individuals that breed further north migrate to locations further south.

MIGRATION AND STOPOVER ECOLOGY OF SONGBIRDS AND BATS ALONG A MAJOR ECOLOGICAL BARRIER

, 2020
Migration is a physiologically and energetically demanding period in the life cycle of a migratory animal. Most migrant songbirds alternate between periods of nocturnal flight, when energy is used, and stopover, when energy is accumulated for the next flight period; indeed, songbirds spend most of their time and energy on stopover.

Domination Versus Sisterhoods in the Blood Microbiota of Migrating Birds: Patterns of Within‐ and Between‐Individual Blood Parasite Diversity Revealed Through Metabarcoding

Integrative Zoology, EarlyView.
Avian haemosporidian blood parasites are typically identified through Sanger sequencing of a partial cytochrome b fragment, the MalAvi barcoding region. Next‐generation sequencing is seldom used for avian blood parasite identification; this study demonstrates a higher detection rate of co‐infections via metabarcoding and its possible implications ...
