Seasonal increase of nest height of the Silver-throated Tit (Aegithalos glaucogularis): can it reduce predation risk?

open access: yesAvian Research, 2018
Background Nest predation is usually the main cause of bird nest failure. ‘Predation avoidance hypothesis’ of nest-site selection predicts that birds should prefer nest-sites with higher nesting success.

WILD TURKEY NESTING HABITAT AND SUCCESS RATES

open access: yesWildlife Society Bulletin, 1990
: Nest success rates for the eastern wild turkey (Meleagris gallopavo silvestris) are often low and affect population densities. We determined habitat use and success rates for 38 nesting hens in east‐central Mississippi from 1984 to 1988. Hens preferred

Predicting Annual Fecundity from Nest Success [PDF]

open access: yesThe Open Ornithology Journal, 2008
Nest success, the probability that a nest will fledge offspring, is a widely measured parameter in ornithological studies, and is usually estimated by monitoring the fates of nests throughout a breeding season. Because nest success es- timates are commonly reported in the avian literature, a key question in population studies is how to derive annual ...

Success of Delayed Translocation of Loggerhead Turtle Nests [PDF]

open access: yesThe Journal of Wildlife Management, 2007
ABSTRACT  Sea turtle embryo mortality in natural nests due to environmental and anthropogenic factors can be very high. To increase hatching success of these endangered species, nest translocation to hatcheries immediately after egg‐laying is a common management tool.
