Evaluating the Effectiveness of a Conservation Project on Two Threatened Birds: Applying Expert-Based Threat Analysis and Threat Reduction Assessment in a Mediterranean Wetland

Diversity, 2022
We applied two recent approaches largely used in biological conservation: Threat Analysis (TAN) and Threat Reduction Assessments (TRAs), assessing the effectiveness of a project focused on two water-related bird species (common tern, Sterna hirundo and ...

Geolocator study reveals east African migration route of Central European Common Terns

Avian Research, 2020
Background The majority of European Common Terns (Sterna hirundo) migrate south along the western coast of Europe and Africa, while birds from eastern regions are known to cross the Mediterranean Sea from east to west or migrate along the eastern African

Seabird metapopulations: searching for alternative breeding habitats [PDF]

, 2009
Today, many seabird species nest in port areas, which are also necessary for human economic activity. In this paper, we evaluate, using a metapopulation model, the possibilities for creating alternative breeding sites for the Common Tern (Sterna hirundo)

No evidence of extra-pair paternity in a colonial seabird, the common tern (Sterna hirundo)

, 2004
The incidence of extra-pair paternity and egg dumping was investigated in a colony of common terns (Sterna hirundo), a colonial seabird, in the Venetian lagoon. Ten families were sampled and multilocus DNA fingerprinting analysis was performed.

Laying eggs on the same nest: unusual mixed-species clutch among three colonial shorebirds

Avocetta
Mixed clutches are relatively uncommon among colonial shorebirds and challenging to document. Here, we report the co-occurrence of three species’ eggs, belonging to Pied Avocet Recurvirostra avosetta, Little Tern Sternula albifrons and Common Tern ...

The effect of localized disturbance on the acoustic behavior of the common tern (Sterna hirundo) [PDF]

JASA Express Letters
In this study, passive acoustic monitoring was used to assess the impact of investigator disturbance on the acoustic behavior of a colony of common terns. A graded antipredator response in the colony was hypothesized, which would result in an increase in

Experimental Evidence for Mobilization of Mercury From the Eggshell by the Developing Embryo in an Avian Model Organism

Environmental Toxicology, EarlyView.
ABSTRACT Of the many pollutants wildlife is exposed to, mercury ranks among the most toxic. In birds, mercury does not only accumulate within generations, but also is transferred across generations via maternal offloading in eggs, with higher mercury concentrations found in shells of unhatched eggs.

The comparative breeding ecology of sympatric common and arctic terns in N.E. England [PDF]

, 1999
The life-history traits of two sympatric seabird species, the Common Sterna hirundo and Arctic Tern S. paradisaea, and the flexibility of these traits in relation to short and longer term changes in environmental conditions were measured at Coquet Island,

Genetic variability in Larus argentatus and Sterna hirundo [PDF]

, 1979
Blood serum and egg-white protein samples from individuals representing seven colonies of Larusargentatus, and four colonies of Sterna hirundo were electrophoretically analysed to determine levels of genetic variability and to assess the utility of ...
