Nest Depth and Height Are Associated with Breeding Outcomes in the Small Bee-Eater (Merops orientalis): A Preliminary Field Study from Pakistan

Animals
Nest architecture and surrounding habitat features can strongly influence the reproductive success of cavity-nesting birds; however, quantitative data from natural environments remain limited.

The influence of clutch and brood sizes on nesting success of the biscutate swift, Streptoprocne biscutata (Aves: Apodidae)

Zoologia (Curitiba), 2011
The nesting success of three colonies of Streptoprocne biscutata (Sclater, 1866), and the influence of clutch and brood size on nesting success of species were studied. Overall, apparent nesting success was 58% and Mayfield nesting success was 53%.

Validation of a novel time-to-event nest density estimator on passerines: An example using Brewer's sparrows (Spizella breweri).

PLoS ONE, 2019
Human impacts on natural resources increasingly necessitate understanding of the demographic rates driving wildlife population trends. Breeding productivity in many avian species is the demographic parameter that primarily influences population ...

The effects of land use changes on site occupancy and breeding success of the barn owl (Tyto alba) from 1993 to 2020

Global Ecology and Conservation
Land use changes, driven by human activities such as agricultural intensification and urban expansion, have drastic effects on biodiversity. As these changes are anticipated to continue, understanding species’ adaptations to their evolving habitats is ...

Estimates of Southern White-tailed Ptarmigan daily nest survival from multiple sites in the Southern Rocky Mountains of Colorado

Avian Conservation and Ecology
Estimating vital rates of avian species is important to understand population dynamics and develop potential conservation strategies that target rates for management. Avian species have reduced potential for high annual fecundity in alpine ecosystems due

Measuring congruence between available and selected vegetation at wild turkey nest sites

Wildlife Society Bulletin
Processes underlying nest‐site selection are often considered drivers influencing wild turkey (Meleagris gallopavo ssp.) nest success. Thus, decisions by females to identify nest sites should govern all other components of reproductive habitat selection ...

Post-copulatory competition in a social monogamy system: Sperm morphology correlates with components of reproductive success.

PLoS ONE
Males in socially monogamous species can achieve reproductive success through multiple tactics- by defending paternity within the social nest and siring extra-pair offspring, or both.

Estimating nesting habitat characteristics for the Kentish plover (Anarhynchus alexandrinus) with the effect of substrate and vegetation using a Bayesian network approach.

PLoS ONE
Coastal habitats play an important role in the nesting ecology of shorebirds; however, these habitats are increasingly threatened by human activity and ongoing habitat loss.

Space Use and Movements During Egg Laying Associated With Nest Fate and Female Survival in Eastern Wild Turkeys

Ecology and Evolution
Reproduction is a fundamental aspect of a species' life history that is energetically costly, yet critical for population sustainability and genetic diversity.
