Egg Characteristics of Female Common Terns Are Repeatable, and Vary With Maternal Age and Laying Order [PDF]

open access: yesEcology and Evolution
Avian eggs exhibit striking variability in size, shape, colour, and maculation, not only among but also within species. Technical and analytical advances in image analysis offer the opportunity to understand the factors underpinning this variability ...

First Description of Mergibacter septicus Isolated from a Common Tern (Sterna hirundo) in Germany [PDF]

open access: yesPathogens, 2023
Mergibacter septicus (M. septicus), previously known as Bisgaard Taxon 40, is a recently described species within the Pasteurellaceae family. In this study, we present a M. septicus strain isolated from a common tern (Sterna hirundo) chick that died just

Surveillance of avian malaria and related haemoparasites in common terns (Sterna hirundo) on the Atlantic coast of South America [PDF]

open access: yesParasitology, 2023
Haemosporidia (Apicomplexa, Haemosporida) are protozoa that infect vertebrate blood cells and are transmitted by vectors. Among vertebrates, birds possess the greatest diversity of haemosporidia, historically placed in 3 genera: Haemoproteus ...

Movement patterns of foraging common terns (Sterna hirundo) breeding in an urban environment in coastal Virginia. [PDF]

open access: yesPLoS ONE
Nesting colonial seabirds are prime examples of central-place foragers, animals that must return to a central location (e.g., a breeding colony) after each bout of foraging.

Are morphometrics sufficient for estimating age of pre-fledging birds in the field? A test using common terns (Sterna hirundo). [PDF]

open access: yesPLoS ONE, 2014
Age is a key component of fitness, affecting survival and reproductive capacities. Where it is not possible to study known individuals from birth, morphometrics (predominantly patterns of plumage development for birds) are most often used to estimate age.

High genetic diversity yet weak population genetic structure in European common terns [PDF]

open access: yesScientific Reports
The common tern (Sterna hirundo) is a migratory seabird experiencing a decline in breeding pairs across several European populations due to various threats, including habitat destruction and human disturbance.

Radiotelemetry reveals the dependence of inland tern breeding and foraging habitats on ADCP-identified sediment aggradation reaches in lowland rivers [PDF]

open access: yesScientific Reports
The largest rivers in developed countries have usually been turned into waterways by straightening them and removing large bedforms hampering navigation.

Best practice guidance for recreational and professional drones near colonial breeding birds. [PDF]

open access: yesPLoS ONE
Drone use has increased sharply worldwide over the past decade, leading to more frequent interactions with wildlife. The rapid advancement of drones for ecological monitoring and research has further contributed to these encounters, which may disturb ...

Sex-specific changes in autosomal methylation rate in ageing common terns

open access: yesFrontiers in Ecology and Evolution, 2023
Senescence, an age-related decline in survival and/or reproductive performance, occurs in species across the tree of life. Molecular mechanisms underlying this within-individual phenomenon are still largely unknown, but DNA methylation changes with age ...
