“…We used ArcMap 10.3.1 (ESRI 2011) to scan all the raw data to identify laying or incubation. We considered a cluster of mid-day locations (laying period of 1200–1529; Carpenter et al 2022, Williams and Austin 1988) on consecutive days (2–3 days) to be a potential nest being laid and a cluster of consecutive points over multiple days with most of the locations <30 m from each other to be a potential incubated nest (Conley et al 2015, Wood et al 2018). We confirmed all potential nest sites via visual inspection.…”

“…We calculated movement metrics (e.g., step length and time interval) between each consecutive point using Geospatial Modeling Environment (GME) software (Spatial Ecology LLC 2010). Carpenter et al (2021) presented a detailed description of the movement metrics calculations. We summed movement metrics of consecutive points outside of the buffer to create the distance and duration of each recess.…”

For bird species that exhibit comprehensive parental care (e.g., incubation, brooding, and extended parental care post-fledging), protection of self, as well as juvenile offspring, requires parent birds to have separate but overlapping anti-predator strategies during reproductive phases of the annual cycle. Behavior of nesting hen Meleagris gallopavo (Wild Turkey) may vary due to landscape features (e.g., roads, water source, or pastureland), potentially influencing predator encounter rates at the nest and consequently affecting nest survival. We assessed factors affecting nest survival and hen survival during incubation, including temporal patterns of M. g. osceola (Osceola Wild Turkey) and M.g. silvestris (Eastern Wild Turkey) recess behaviors. We used data on recess bouts from 37 hens fitted with global positioning system (GPS) transmitters and 54 confirmed nest attempts in north and north-central Florida to determine the effect of nest attendance on nest survival. On average, hens took 0.89 incubation recess bouts between 0800 and 1800, usually in the afternoon. Hen survival increased with an increase in daily recess bouts, longer daily recess bouts, and later nest incubation-initiation dates, and the probability of nest survival increased when hens took longer afternoon recess bouts. Nest survival was greater in the north-central region. These results indicate increases in recess duration contribute to greater hen and nest survival, which may be due to reduced nest-predator activity in the afternoon at the study sites. We recommend additional research into the relationship between predator activity and nesting Wild Turkeys on managed lands similar to those in our study.
