An impact evaluation of conservation investments targeting long‐distance migratory species

open access: yesConservation Biology, Volume 38, Issue 3, June 2024.
Abstract We evaluated the impact of a philanthropic program investing in the conservation of sites along the Pacific Americas Flyway, which spans >16,000 km of coastline and is used by millions of shorebirds. Using a quasi‐experimental, mixed methods approach, we estimated what would have happened to shorebird populations at 17 wintering sites without ...

Assessing shorebird mortalities due to razor clam aquaculture at key migratory stopover sites in southeastern China

open access: yesConservation Biology, Volume 38, Issue 2, April 2024.
Abstract Aquaculture can provide foraging habitat for birds, but it can also result in intentional and accidental mortality. We examined an overlooked conflict between razor clam (Sinonovacula spp.) aquaculture and declining shorebirds in southeastern China's Fujian and Zhejiang provinces.

Interactions between shorebirds and benthic invertebrates at Culbin Sands lagoon, NE Scotland: effects of avian predation on their prey community density and structure [PDF]

open access: yes, 2007
In the North Sea, during autumn-winter, intertidal flats often receive a massive influx of migratory shorebirds (wildfowl, waders and seabirds), which utilise the high prey densities that are available.

Effects of wind turbine noise on songbird behavior during nonbreeding season

open access: yesConservation Biology, Volume 38, Issue 2, April 2024.
Abstract Anthropogenic noise is one of the fastest growing, globally widespread pollutants, affecting countless species worldwide. Despite accumulating evidence of the negative impacts of wind turbines on wildlife, little is known about how the noise they generate affects ecological systems.

Aves migratorias neárticas en comunidades templadas y tropicales

open access: yesEl Hornero, 1979
Populations of over 300 species of birds that breed in America, north of Mexico, spend a portion of their life cycle in the tropical zone. Studies in Veracruz, Mexico, and elsewhere in the tropics have shown that there is intense intraspecific competition, fidelity to wintering sites, and niche specificity in migrants using these tropical environments.

Nighthawk: Acoustic monitoring of nocturnal bird migration in the Americas

open access: yesMethods in Ecology and Evolution, Volume 15, Issue 2, Page 329-344, February 2024.
Abstract Animal migration is one of nature's most spectacular phenomena, but migratory animals and their journeys are imperilled across the globe. Migratory birds are among the most well‐studied animals on Earth, yet relatively little is known about in‐flight behaviour during nocturnal migration.
