Colony size as a predictor of breeding behaviour in a common waterbird.

open access: yesPLoS ONE, 2020
The choice of colony size may have profound consequences for individual fitness in colonially breeding birds, but at the same time it may require certain behavioural adaptations.

Nest success of ground‐nesting ducks in the wetlands of Great Salt Lake, Utah

open access: yesEcology and Evolution, 2023
The number of ground‐nesting ducks in the wetlands of Great Salt Lake, Utah has drastically decreased in the past few decades. A potential cause for this decline is the increase of predator species and their abundances, which has caused most nests to ...

Evidence of continued exposure to legacy persistent organic pollutants in threatened migratory common terns nesting in the Great Lakes

open access: yesEnvironment International, 2020
Persistent organic pollutants (POPs) accumulate in the food web of the Great Lakes ecosystem, causing concern that these chemicals play a role in the decline of avian species such as colonial-nesting waterbirds.

High individual repeatability of the migratory behaviour of a long-distance migratory seabird

open access: yesMovement Ecology, 2022
Background Understanding the evolution of migration requires knowledge of the patterns, sources, and consequences of variation in migratory behaviour, a need exacerbated by the fact that many migratory species show rapid population declines and require ...

The use of artificial floating nest platforms as conservation measure for the common tern Sterna hirundo: a case study in the RAMSAR site Druzno Lake in Northern Poland

open access: yesThe European Zoological Journal, 2022
Artificial nesting sites with floating platforms may effectively support local breeding populations of waterbirds (enhancing productivity and survival) when natural sites are unavailable.

Colony and nest site selection by roseate and common terms in the Azores archipelago - a multivariate analysis [PDF]

open access: yes, 1990
Multivariate techniques were used to examine overall characteristics of colonies, and detailed characteristics of nest sites within colonies, of Roseate and Common terns in the Azores archipelago.

Distribution and breeding of the slender-billed gull Chroicocephalus genei, common tern Sterna hirundo and little tern Sternula albifrons in Algeria

open access: yes, 2018
The knowledge of the breeding ecology of terns and gulls in the Maghreb lags far behind that of other species. In this paper, we present data on the distribution and breeding of three species, Slender-billed Gull Chroicocephalus genei, Little Tern ...

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

open access: yesAnimal 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 ...

Waterbird community changes in the Wilderness Lakes, South Africa (Part 3 of 3): Diving piscivores and scavengers

open access: yesKoedoe: African Protected Area Conservation and Science, 2023
Estuarine waterbodies typically support diverse and abundant waterbird communities. However, global environmental degradation as a result of anthropogenic activities is leading to species level changes in biodiversity, with top predators such as ...
