“…mammals and cowbirds) that do not need to switch to natural foods during the breeding season to support growing young, as do crows. Second, bird feeders may have buffered the risk of nest predation for cardinals that directly consume birdseed, unlike adult robins (Halkin andLinville 1999, Vanderhoff et al 2016). Access to supplementary food such as birdseed may reduce nest predation risk for cardinals by minimizing the time spent foraging or the frequency at which birds leave and return to nests (Martin 1992, Komdeur and Kats 1999, Rastogi et al 2006, Lima 2009).…”

“…Northern Cardinals may also exhibit increased nest survival as vegetation recovers after disturbance if concealment improves nest survival. Available data suggests that the species experiences moderate to low nest survival in many locations studied to date, but is very tolerant of habitat disturbance [38]. In the Gulf Coastal Plain study site, which had the largest sample sizes of nests, cardinal nest survival was variable and not clearly associated with treatments [39].…”

Abstract:We examined the initial response of avian nest success to mechanical thinning, prescribed fire, and thinning/ prescribed fire combination treatments, designed to reduce fuel loads, at study sites throughout the continental USA as part of the National Fire and Fire Surrogate (FFS) Project. We modeled the daily nest survival of ground-, shrub-, tree-, and snag-nesting bird species to test for effects of: (1) overall treatment (2) specific treatment category (i.e., burn, thin, thin/burn); (3) time since treatment; and (4) study site. Of the 7 species examined, only 2 had top models that included effects of the FFS treatments, the remainder had either constant survival rates, or rates that varied only by study site. The Eastern Towhee had top models that included effects of treatment and study site, while the Red-bellied Woodpecker had top models that included effects of treatment category, time since treatment, and study site. All estimates of treatment, treatment category, and study site were statistically weak with confidence intervals including zero. The lack of clear response patterns observed in this study is likely a consequence of the variability inherent across forest types and taxonomic groups we examined. Forest managers should use our results cautiously and also be encouraged to facilitate opportunities for studies of avian nest survival as a function of fire-surrogate treatments that are regional specific, encompass longer time frames and larger spatial scales.

“…Cardinals are year-round residents that nest in understory and midstory vegetation and defend territories during the breeding season (Halkin and Linville, 1999). Breeding densities of cardinals are highest in sites with dense understory shrubs (Leston and Rodewald, 2006), particularly Amur honeysuckle (Lonierca mackii), an exotic shrub that is preferred as a nesting substrate and can act as an ecological trap (Rodewald et al, 2010).…”

Human activities are leading to rapid environmental change globally and may affect the eco-evolutionary dynamics of species inhabiting human-dominated landscapes. Theory suggests that increases in environmental heterogeneity should promote variation in reproductive performance among individuals. At the same time, we know that novel environments, such as our urbanizing study system, may represent more benign or predictable environments due to resource subsidies and ecological changes. We tested the hypothesis that reduced environmental heterogeneity and enhanced resource availability in cities relax selective pressures on birds by testing if urban females vary less than rural females in their demographic contributions to local populations. From 2004 to 2014, we monitored local population densities and annual reproductive output of 470 female Northern Cardinals (Cardinalis cardinalis) breeding at 14 forested sites distributed across a rural-to-urban landscape gradient in Ohio, USA. Reproductive contribution was measured as the difference between individual and site-averaged annual reproductive output across all nesting attempts, divided by the annual density at each site. We show that among-individual variation in reproductive contribution to the next year's population declined with increasing urbanization, despite similar variability in body condition across the rural-urban gradient. Thus, female cardinals that bred in urban habitats within our study area were more similar in their contribution to the next generation than rural breeders, where a pattern of winners and losers was more evident. Within-individual variation in annual reproductive contribution also declined with increasing urbanization, indicating that performance of females was also more consistent among years in urban than rural landscapes. These findings are consistent with the hypothesis that urbanized environments offer more homogeneous or predictable conditions that may buffer individuals from environmental heterogeneity and relax natural selection.
