Social interactions of juvenile brown boobies at sea as observed with animal-borne video cameras. [PDF]

PLoS ONE, 2011
While social interactions play a crucial role on the development of young individuals, those of highly mobile juvenile birds in inaccessible environments are difficult to observe.

Variations in inter-specific and sex-related niche partitioning in pelagic boobies during their annual cycle. [PDF]

Ecol Evol
Inter‐ and intra‐specific niche partitioning in tropical seabird species during the breeding period and in the more‐dimorphic species. Abstract Animals that co‐occur in a region (sympatry) may share the same environment (syntopy), and niche differentiation is expected among closely related species competing for resources.

Island restoration to rebuild seabird populations and amplify coral reef functioning. [PDF]

Conserv Biol
Abstract Mobile organisms like seabirds can provide important nutrient flows between ecosystems, but this connectivity has been interrupted by the degradation of island ecosystems. Island restoration (via invasive species eradications and the restoration of native vegetation) can reestablish seabird populations and their nutrient transfers between ...

Recovery of insular seabird populations years after rodent eradication

Conservation Biology, Volume 37, Issue 3, June 2023., 2023
Abstract Seabirds have been particularly affected by invasive non‐native species, which has led to the implementation of numerous eradication campaigns for the conservation of these keystone and highly vulnerable species. Although the benefits of eradication of invasive non‐native species for seabird conservation have been demonstrated, the recovery ...

Avian influenza overview December 2022 – March 2023

EFSA Journal, Volume 21, Issue 3, March 2023., 2023
Abstract Between 3 December 2022 and 1 March 2023 highly pathogenic avian influenza (HPAI) A(H5N1) virus, clade 2.3.4.4b, was reported in Europe in domestic (522) and wild (1,138) birds over 24 countries. An unexpected number of HPAI virus detections in sea birds were observed, mainly in gull species and particularly in black‐headed gulls (large ...

A survey of the uncinate bone and other poorly known ossicles associated with the lacrimal/ectethmoid complex of the avian skull

The Anatomical Record, Volume 305, Issue 9, Page 2312-2330, September 2022., 2022
Abstract In several taxa of Neornithes (crown group birds), the lacrimal/ectethmoid complex exhibits small bones, the comparative osteology of which is poorly studied. Some of these ossicles—which are commonly known as uncinate bones (ossa uncinata or ossa lacrimopalatina)—were already described two centuries ago, but knowledge of their distribution ...

Food restriction delays breeding and affects insulin‐like growth factor‐1, oxidative damage and haematocrit value before egg‐laying in female canaries

Journal of Avian Biology, Volume 2022, Issue 4, April 2022., 2022
Environmental challenges, such as fluctuations in food availability, could influence reproductive investment. If resource availability is poor, individuals need to decide in which life‐history process they invest more energy and vital compounds, which determine the cost of reproduction.
