Comparing timing and routes of migration based on ring encounters and randomization methods [PDF]

Animal Biodiversity and Conservation, 2004
A method for comparing two migration routes is introduced. In the method are needed approximations of the average daily positions which are computed based on averages of dates and of positions in a window sliding through the encounters ordered in ...

‘O sibling, where art thou?’ – a review of avian sibling recognition with respect to the mammalian literature [PDF]

, 2004
Avian literature on sibling recognition is rare compared to that developed by mammalian researchers. We compare avian and mammalian research on sibling recognition to identify why avian work is rare, how approaches differ and what avian and mammalian ...

Waarnemingen bij een vermoedelijk gemengd broedpaar Dougalls stern, Sterna dougallii, X visdief, Sterna hirundo te Knokke [PDF]

, 1977
From 9 May to 9 August 1976 a Roseate Tern resided in the colony of Common Terns at the Zwin (Knokke). It was apparently a male that eventually palred with a female Common Tern. At least one chick was raised.

Age dependent reproductive effort in great tits

Journal of Avian Biology, Volume 2026, Issue 1, January 2026.
Senescence, the decline in reproductive value with age, is well documented in natural systems, but the underlying mechanisms remain an enigma. A decline in parental effort with age potentially explains reproductive senescence, but age effects on parental effort have been little investigated.

Testing for assortative mating based on migratory phenotypes in the Common Tern (Sterna hirundo)

Avian Research
Tracking and mating data of Common Terns (Sterna hirundo) breeding in a single colony in north-eastern Germany were used to test for assortative mating in regards to migratory phenotypes.

Using Historic and Contemporary Genomes to Assess the Genetic Consequences of a Population Decline in an Endangered Tern Population

Evolutionary Applications, Volume 19, Issue 1, January 2026.
ABSTRACT Many migratory species have experienced severe population declines, but the genetic consequences of such declines are still rarely assessed. The last Central European population of gull‐billed terns (Gelochelidon nilotica) has declined from 500 breeding pairs in the 1940s to 52 in 2025, whereas Mediterranean populations of this migratory ...

Nest‐site selection by cinnamon teal and other ground‐nesting ducks in Great Salt Lake wetlands

Wildlife Society Bulletin, 2023
Ground‐nesting ducks can reduce nest depredation by selecting nest sites where local physical structures or vegetation provide olfactory or visual concealment.

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.

Floating rafts as breeding habitats for the Common tern, Sterna hirundo. Colonization patterns, abundance and reproductive success in Venice Lagoon

Rivista Italiana di Ornitologia - Research in Ornithology, 2018
The Venice lagoon hosts the 15% of the entire Italian breeding population of Common terns, Sterna hirundo, highlighting the great value of the area for this species.
