Successful breeding predicts divorce in plovers [PDF]

open access: yesScientific Reports, 2020
AbstractWhen individuals breed more than once, parents are faced with the choice of whether to re-mate with their old partner or divorce and select a new mate. Evolutionary theory predicts that, following successful reproduction with a given partner, that partner should be retained for future reproduction. However, recent work in a polygamous bird, has

Reproductive Consequences of Nest Site Use in Fork-tailed Storm-Petrels in the Aleutian Islands, Alaska: Potential Lasting Effects of an Introduced Predator

open access: yesAvian Conservation and Ecology, 2010
We examined the reproductive consequences of differential nest site use in Fork-tailed Storm-Petrels (Oceanodroma furcata) in the Aleutian Islands, Alaska, where birds on islands where foxes were introduced nest in rocky substrate rather than in typical ...

On the breeding behaviour of leucistic birds: case study in the Blackbird (Turdus merula) [PDF]

open access: yesTichodroma
The breeding behaviour of leucistic birds is poorly known. The Blackbird is the species in which leucism occurs most frequently in Europe. In Slovakia, a total of 35 records of leucistic individuals with different range of white coloration have been ...

Compensatory Breeding in Years Following Drought in a Desert-Dwelling Cooperative Breeder

open access: yesFrontiers in Ecology and Evolution, 2020
Variation in weather patterns can influence reproductive effort and success not only within but also between breeding seasons. Where environmental conditions can be highly variable between years, the weather, and particularly extreme weather events such ...

The effects of four decades of climate change on the breeding ecology of an avian sentinel species across a 1,500‐km latitudinal gradient are stronger at high latitudes

open access: yesEcology and Evolution, 2021
Global warming affects breeding phenology of birds differentially with latitude, but there is contrasting evidence about how the changing climate influences the breeding of migrating songbirds at their northern breeding range.
