Early nest initiation and vegetation density enhance nest survival in Wild Turkeys
<p>The theory of adaptive habitat selection suggests resource selection by animals should reflect underlying quality, such that individual selection confers an adaptive advantage via increased fitness. Using resource selection functions and nest survival models, we demonstrated that visual obstruction at the nest site was adaptively significant but timing of nest initiation had the greatest effect on nest survival for eastern wild turkeys (Meleagris gallopavo silvestris). Predation risk is a selective pressure, and if individuals can perceive predation risk, they may respond by altering selection of nest site characteristics based on prior experience. We evaluated patterns in nest site selection of 387 wild turkeys and consequences of selection on reproductive success across the southeastern United States from 2014-2019. We monitored 549 nest sites and found that nest initiation date had the strongest effect on daily nest survival rates, wherein adult females at our earliest nest initiation date were ~ 4 times more likely to successfully nest than females at our latest nest initiation dates. Selection of nest sites with greater visual obstruction also increased daily nest survival rates as females were 1.17 (1.100 – 1.234; 95% CI) and 1.37 (1.258 – 1.486; 95% CI) times more likely to select sites for every 10 cm increase in visual obstruction and maximum vegetation height, respectively. Collectively, our results indicate that nest initiation date is likely the critical parameter driving wild turkey nest success, whereas vegetative conditions play a lesser role influencing nest success. Females nesting earlier may be in better body condition and show increased nest attentiveness, which may mediate nest success more than vegetation conditions around nest sites. Our work indicates that increasing the reproductive success of wild turkeys may hinge on females being able to nest as early as possible within the reproductive season.</p>
Data from: Inter-annual climate variation influences nest initiation date and nest productivity of the Red-cockaded Woodpecker at the northwestern edge of its range
<p>Climate change, including directional shifts in weather averages and extremes and increased inter-annual weather variation, is influencing demograhy and distributions for many bird species. We examined how temperature and precipitation coinciding with multiple nesting seasons affected overall nesting success and productivity for two red-cockaded woodpecker (<em>Dryobates borealis,</em> RCW) populations at the species' northwestern range periphery. We used 26 years of nesting data (1991-2016) from the two RCW populations to determine if inter-annual weather variation has affected nesting pehnology and productivity. We conducted analyses at both broad nesting periods (30 and 60 days before nesting; 40 days overalpping the nesting period up to fledging) and short windows to capture the effects of temperature and precipitation extremes on individual nests. For both RCW populations, warmer early spring temperatures generally advanced nesting and increased clutch size and fledgling number. However, effects of average precipitation varied depending on amount and duration of precipitation in different time periods. At the nest level, temperature and precipitation extremes were unrelated to nest success and loss of nestlings (brood loss). Our results indicate that RCWs are responding to the effects of climate change in various ways, with warming trends having a positive benefit on the species at its northwestern range periphery.</p>
Nest initiation and end dates for eight grassland bird species in Wisconsin and Illinois
<p>We used nest records from published grassland bird studies done in Wisconsin and Illinois to compile a dataset for 8 obligate grassland bird species Study sites were clustered in southwestern Wisconsin near Mt. Horeb (43.0167°N, 89.7500°W); sites were located in Dane, Grant, Green, Iowa, Lafayette, Monroe, and Rock counties. In northern Illinois, study sites were located in Lee, Ogle, Will, Grundy, Carroll, and Jo Daviess counties (40.9822 to 42.2356°N, -87.5433 to -90.3489°W).The dataset consists of 3257 nests with observations on nest initiation date (date first egg laid), nest fate (success, failure), number of fledglings, and nest end date (date the nest either failed or fledged at least one nestling). The species were Bobolink, Dickcissel, Eastern Meadowlark, Grasshopper Sparrow, Henslow's Sparrow, Savannah Sparrow, Vesper Sparrow, and Western Meadowlark. </p>

Data from: Nest-box temperature affects clutch size, incubation initiation, and nestling health in great tits
Prenatal maternal effects can be a source of phenotypic plasticity and may play a role in adaptation to climate change. However, we do not know how far temperature could influence such effects, if at all. We studied the influence of temperature during egg laying on maternal reproductive investment and on the phenotype of adult females, adult males, and nestlings. We expected temperature to have an effect, as it influences maintenance costs for females, who can also use it as a cue of the advancement of the breeding season. We experimentally increased night-time nest-box temperatures by approximately 1 °C throughout the entire laying period in great tits (Parus major). Clutch size was negatively correlated with laying date in heated females. Heated females did not delay incubation after clutch completion as frequently as control females did. Finally, blood sedimentation rate, which is an indicator of acute infections and inflammatory diseases, was positively correlated with hatching date in control broods. This suggests that nestlings were of lower quality in late-hatched broods than in early-hatched broods. This seasonal effect was not detected in heated nests. Our results show that a small increase in temperature during laying can influence breeding strategy and nestling characteristics. These results suggest that birds used temperature as a cue of seasonal advancement to adjust breeding phenology, with beneficial effects on nestling health. To better understand the consequences of maternal adjustments during egg laying, it would be interesting to combine studies with heating treatment during different periods of the breeding cycle.
