Effects of oil and gas development on duck nest survival in the Western Boreal Forest

open access: yesAvian Conservation and Ecology
Nest survival drives population demographics of most avian species. Researchers and managers have focused studies on investigating nest success in association with climate, land use change (e.g., agriculture), and predators in the Prairie and Arctic ...

Patterns in avian reproduction in the Prudhoe Bay Oilfield, Alaska, 2003–2019

open access: yesJournal of Avian Biology, 2023
The Arctic Coastal Plain is one of the most important avian breeding grounds in the world; however, many species are in decline. Arctic‐breeding birds contend with short breeding seasons, harsh climatic conditions, and now, rapidly changing, variable ...

Nest survival rate of Reeves's pheasant (Syrmaticus reevesii) based on artificial nest experiments. [PDF]

open access: yesZool Res, 2017
To explore the nest survival rate of Reeves's pheasant(Syrmaticus reevesii) and the nest-site factors that affect it, we conducted artificial nest experiments with reference to natural nests at Dongzhai National Nature Reserve(DNNR), Henan Province and Pingjingguan, Hubei Province from April to June 2014 simulating the situation in its early and later ...

Nest Survival Patterns in Willow Ptarmigan: Influence of Time, Nesting Stage, and Female Characteristics

open access: yes, 2007
Nest predation is the most important factor limiting reproductive success of Willow Ptarmigan (Lagopus lagopus), as it is for many bird species. Using program MARK, we examined patterns of daily nest survival in two widely separated populations of Willow

Striped-tailed Yellow-finch nesting success in abandoned mining pits from central Brazilian cerrado

open access: yesBrazilian Journal of Biology
Suitability of degraded areas as breeding habitats can be tested through assessment of nest predation rates. In this study we estimated nest success in relation to several potential predictors of nest survival in the Stripe-tailed Yellow-finch (Sicalis ...

Hydrology management influences nest survival but not clutch size in Lesser Scaup

open access: yesAvian Conservation and Ecology, 2022
Components of reproductive success such as clutch size and nest survival may greatly affect avian population growth rates. Understanding how environmental conditions influence temporal variation in these demographic parameters could thus provide valuable

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 ...

Factors influencing productivity of eastern wild turkeys in northeastern South Dakota

open access: yesEcology and Evolution, 2020
Population growth is highly sensitive to changes in reproductive rates for many avian species. Understanding how reproductive rates are related to environmental conditions can give managers insight into factors contributing to population change.

Lesser Prairie‐chicken incubation behavior and nest success most influenced by nest vegetation structure

open access: yesEcology and Evolution, 2023
Incubation breaks are necessary for any nesting bird but can increase the mortality risk of the nest or attending parent. How intrinsic and extrinsic variables affect nest attentiveness—the proportion of time a female is on nest during incubation— and ...
