Population trends of resident and migratory Canada geese in relation to strikes with civil aircraft
Human-Wildlife Interactions, 2017 Canada geese (Branta canadensis) are of particular concern to aviation in the USA because of their large size, flocking behavior, attraction to airports for grazing, and, for the resident population, year-round presence in urban environments.

Analysis of Bird Flyways in 3D [PDF]
ISPRS International Journal of Geo-Information, 2019 Bird migration is a long studied phenomenon that involves animals moving back and forth from wintering sites and to reproductive grounds. Several studies have focused on identifying the timing, physiology and evolution of migration, but a spatial approach to understand the migratory routes is still an open challenge.

Southward autumn migration of waterfowl facilitates cross-continental transmission of the highly pathogenic avian influenza H5N1 virus. [PDF]
, 2016 The highly pathogenic avian influenza subtype H5N1 (HPAI H5N1) is a worldwide zoonotic infectious disease, threatening humans, poultry and wild birds. The role of wild birds in the spread of HPAI H5N1 has previously been investigated by comparing disease

At-sea abundance and distribution of skuas and jaegers (Charadriiformes: Stercorariidae) at coastal waters off central Chile [PDF]
, 2014 Indexación: Web of Science; Scielo.BACKGROUND: Skuas and jaegers (Charadriiformes: Stercorariidae) are seabirds breeding at moderate to high latitudes and some perform extensive post-breeding transequatorial migrations.

Ecosphere, 2021 Preserving avian flyway connectivity has long been challenged by our capacity to meaningfully quantify continental habitat dynamics and bird movements at temporal and spatial scales underlying long‐distance migrations.

Population consequences of migratory variability differ between flyways [PDF]
Current Biology, 2018 Long-distance migratory bird populations are likely to be declining because of climate change shifting habitats or anthropogenic habitat loss [1], but this may be mediated by the size of the non-breeding area over which a population spreads (migratory spread), and migration distance (or number of stop-over sites).

Global Ecology and Conservation, 2020 • The decline of submerged macrophytes in shallow lakes and wetlands has cascade effects on regional and global biodiversity. In the last two decades, the rapid disappear of macrophyte beds in the floodplain lakes of the middle lower Yangtze River has ...

Flyway structure in the circumpolar greater white‐fronted goose [PDF]
Ecology and Evolution, 2018 AbstractDispersal and migratory behavior are influential factors in determining how genetic diversity is distributed across the landscape. In migratory species, genetic structure can be promoted via several mechanisms including fidelity to distinct migratory routes.

Climate-driven flyway changes and memory-based long-distance migration [PDF]
Nature, 2021 Millions of migratory birds occupy seasonally favourable breeding grounds in the Arctic1, but we know little about the formation, maintenance and future of the migration routes of Arctic birds and the genetic determinants of migratory distance. Here we established a continental-scale migration system that used satellite tracking to follow 56 peregrine ...
