Nest-site habitat partitioning by Arctic, Common, and Roseate terns

Avian Conservation and Ecology
When closely related species that share aspects of their habitat niches nest in sympatry, selection is expected to favor species-specific differences in nest-site selection that allow birds to partition habitat. We tested habitat-partitioning theory in a

Sex-biased mortality of common terns in wind farm collisions [PDF]

, 2008
We studied sex differences in collision mortality in adult Common Terns (Sterna hirundo) at a wind farm in the direct vicinity of a breeding site in Zeebrugge, Belgium in 2005-2007.

Natal philopatry, dispersal and age of first breeding in relation to size and sex of Arctic Terns (Sterna paradisaea)

Ibis, Volume 168, Issue 1, Page 79-94, January 2026.
Many seabird species are in decline and population demographic models are important for revealing the causes and developing conservation strategies. Natal and breeding dispersal are key parameters of such models but can be challenging to estimate and may vary by sex.

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.

Source amplitude increases with body‐mass across avian genera

Ibis, Volume 168, Issue 1, Page 127-139, January 2026.
Amplitude, or intensity, of sound is a fundamental characteristic of acoustic communication, with relevance in many scientific fields. The amplitude of an animal's acoustic signal at its source (‘source amplitude’) may be particularly relevant in the field of acoustic allometry, where relationships between species' physical and acoustic features (e.g ...

The impacts of sleep disturbance on birds: a review of the knowledge gaps

Journal of Avian Biology, Volume 2025, Issue 5, September 2025.
Sleep is an evolutionarily conserved behaviour critical to animal function. While the exact functions of sleep are still unclear, the ubiquity of sleep behaviour and its potential high costs (e.g. reduction in foraging time, increased vulnerability to predators) suggest sleep serves a critical role for animals.

Nest‐site fidelity of Arctic terns Sterna paradisaea in a managed environment exposed to benign human activity

Wildlife Biology, Volume 2025, Issue 4, July 2025.
Human activity near seabird colonies is often equated with disturbance. Coping with human disturbance is a critical task in the management of seabird colonies where human access is an issue. Nest‐site fidelity and breeding dispersal were characterised in an Arctic tern population exposed to a high level of benign human activity from resident ...

Adjustment of the annual cycle to climatic change in a long-lived migratory bird specie

Current Zoology, 2009
Climate change has advanced the phenology of many organisms. Migratory animals face particular problems because climate change in the breeding and the wintering range may be asynchronous, preventing rapid response to changing conditions. Advancement in

Risk posed by the HPAI virus H5N1, Eurasian lineage goose/Guangdong clade 2.3.4.4b. genotype B3.13, currently circulating in the US

EFSA Journal, Volume 23, Issue 7, July 2025.
Abstract The emergence of highly pathogenic avian influenza (HPAI) A(H5N1), clade 2.3.4.4b, genotype B3.13 in U.S. dairy cattle marks a significant shift in the virus' host range and epidemiological profile. Infected cattle typically exhibit mild clinical signs, such as reduced milk production, mastitis and fever, with morbidity generally below 20% and

Voedsel en groei van kuikens van de Velduil Asio flammeus op Griend [PDF]

, 1997
One pair of Short-eared Owls nested on Griend, an islet in the Dutch Wadden Sea, in 1992, 1994, 1995 and 1996. The species never bred on Griend prior to the 1990s. In the four years one, one, four and zero chicks fledged.
