According to one study regarding the Wood Thrush, what percentage of nest failures that did not fledge young were attributed to predation?
Answer
71 percent
Nesting presents one of the most critical vulnerability periods for thrushes, particularly species that rely on deep forest habitats. For the Wood Thrush specifically, detailed observation revealed a substantial toll taken by predators during the nesting phase. In one documented study focusing on reproductive success, an overwhelming majority—precisely 71 percent—of all nests that ultimately failed to successfully rear and fledge young were lost directly due to predatory activity. This statistic underscores the intense pressure exerted by animals targeting eggs and nestlings, which contributes significantly to the overall low survival rate observed in the species' early life.
