Comparative nest survival of three sympatric loon species breeding in the Arctic

open access: yesJournal of Avian Biology, 2018
Identifying factors influencing nest survival among sympatric species is important for understanding and managing sources of variation in population dynamics of individual species.

Nest-site selection and breeding success of passerines in the world’s southernmost forests [PDF]

open access: yesPeerJ, 2020
Background Birds can maximize their reproductive success through careful selection of nest-sites. The ‘total-foliage’ hypothesis predicts that nests concealed in vegetation should have higher survival.

Canada goose nest survival at rural wetlands in north‐central Iowa

open access: yesWildlife Society Bulletin, 2016
The last comprehensive nest survival study of the breeding giant Canada goose (Branta canadensis maxima) population in Iowa, USA, was conducted >30 years ago during a period of population recovery, during which available nesting habitat consisted ...

Mitigation Effectiveness for Improving Nesting Success of Greater Sage-Grouse Influenced by Energy Development [PDF]

open access: yes, 2015
Sagebrush Artemisia spp. habitats being developed for oil and gas reserves are inhabited by sagebrush obligate species--including the greater sage-grouse Centrocercus urophasianus (sage-grouse) that is currently being considered for protection under the ...

Behavioral strategies during incubation influence nest and female survival of Wild Turkeys

open access: yesEcology and Evolution, 2020
Females must balance physiological and behavioral demands of producing offspring with associated expenditures, such as resource acquisition and predator avoidance. Nest success is an important parameter underlying avian population dynamics.

Fully accounting for nest age reduces bias when quantifying nest survival [PDF]

open access: yesOrnithological Applications, 2021
AbstractAccurately measuring nest survival is challenging because nests must be discovered to be monitored, but nests are typically not found on the first day of the nesting interval. Studies of nest survival therefore often monitor a sample that overrepresents older nests. To account for this sampling bias, a daily survival rate (DSR) is estimated and

The Modified Pharaoh Approach: Stingless bees mummify beetle parasites alive [PDF]

open access: yes, 2008
Social insect colonies usually live in nests, which are often invaded by parasitic species^1^. Workers from these colonies use different defence strategies to combat invaders^1^.

Nest density drives productivity in chestnut-collared longspurs: Implications for grassland bird conservation.

open access: yesPLoS ONE, 2021
Grassland birds are declining faster than any other avian guild in North America and are increasingly a focus of conservation concern. Adaptive, outcome-based management of rangelands could do much to mitigate declines.

Drivers of nest survival rate in a southern Tunisian population of Laughing Doves (Spilopelia senegalensis)

open access: yesAvian Research, 2019
Background Investigating the ecological factors and processes shaping nest survival is of great importance for assessing the breeding success of bird populations and understanding their spatio-temporal dynamics.

Effects of habitat and livestock on nest productivity of the Asian houbara Chlamydotis macqueenii in Bukhara Province, Uzbekistan [PDF]

open access: yes, 2016
To inform population support measures for the unsustainably hunted Asian houbara Chlamydotis macqueenii (IUCN Vulnerable) we examined potential habitat and land-use effects on nest productivity in the Kyzylkum Desert, Uzbekistan.
