Movements, home-range size and habitat selection of mallards during autumn migration. [PDF]

PLoS ONE, 2014
The mallard (Anas platyrhynchos) is a focal species in game management, epidemiology and ornithology, but comparably little research has focused on the ecology of the migration seasons.

Migration strategy predicts stopover ecology in shorebirds on the northern Gulf of Mexico

Animal Migration, 2015
AbstractTwenty-eight species of migratory shorebirds rely on the coastlines of the northern Gulf of Mexico (NGOM) to fuel migrations to near-arctic breeding grounds. Shorebird species vary in their migration ecology: some species use a “jump” strategy, migrating long distances without stopping, while others use “skip” and “hop” strategies, stopping to ...

Shorebird responses to fine‐scale water level fluctuations and macrofauna biomass in a newly constructed freshwater wetland

Restoration Ecology, EarlyView.
Abstract Introduction Restoration of marine and freshwater wetlands for shorebirds is essential for the recovery of their declining populations. An ongoing approach is to restore shorebird habitats by large‐scale engineering, expecting the return of birds once suitable abiotic conditions are (re)established.

Multi‐Seasonal eDNA Metabarcoding Highlights a Resurgence in Fish Diversity Across a Severely Impacted Estuarine Ecosystem

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Aquatic ecosystems have been in an alarming state of decline for decades. In particular, estuarine ecosystems have experienced long‐term declines in fish diversity due to factors such as habitat degradation, pollution and altered hydrology. Monitoring these systems is often limited by the difficulty and cost of conventional survey methods.

Migration Patterns, Use of Stopover Areas, and Austral Summer Movements of Swainson\u27s Hawks [PDF]

, 2011
From 1995 to 1998, we tracked movements of adult Swainson’s Hawks (Buteo swainsoni), using satellite telemetry to characterize migration, important stopover areas, and movements in the austral summer.

Spatial Segregation and Trophic Niche Divergence in Two Disjunct Populations of Wedge‐Tailed Shearwater Ardenna pacifica in Eastern Australia

Ecology and Evolution, Volume 16, Issue 3, March 2026.
This study investigated habitat use and trophic niche differentiation in two wedge‐tailed shearwater populations in eastern Australia (2015 to 2019). Temperate birds foraged mainly in southeastern Australian waters and undertook a pre‐staging detour towards the subtropical frontal zone before migration, whereas subtropical birds foraged further east ...

Female migration phenology and climate conditions explain juvenile Red Knot (Calidris canutus rufa) counts during fall migration

Avian Conservation and Ecology, 2022
The management of avian populations at risk requires accurate estimates of vital rates across age and sex classes to effectively identify the most vulnerable demographic and support conservation actions. In the endangered Red Knot (Calidris canutus rufa),

Modeling the Geography of Migratory Pathways and Stopover Habitats for Neotropical Migratory Birds

Ecology and Society, 2003
Intact migratory routes are critical for the stability of forest-dwelling, neotropical, migratory bird populations, and mortality along migratory pathways may be significant.

Both short and long distance migrants use energy-minimizing migration strategies in North American herring gulls

Movement Ecology, 2020
Background Recent studies have proposed that birds migrating short distances migrate at an overall slower pace, minimizing energy expenditure, while birds migrating long distances minimize time spent on migration to cope with seasonal changes in ...

The migration of the great snipe Gallinago media: intriguing variations on a grand theme [PDF]

, 2016
The migration of the great snipe Gallinago media was previously poorly known. Three tracks in 2010 suggested a remarkable migratory behaviour including long and fast overland non-stop flights (Klaassen et al. 2011).
