Sea-level rise may be a big problem for saltmarsh birds, but so is predation, and birds sometimes find themselves caught between a rock and a hard place: They can place their nests lower in the vegetation to avoid predators, putting them at greater risk of flooding, or move them up to keep them dry but risk getting eaten. A new study from The Condor: Ornithological Applications finds that greater pressure from predators increases the risk of flooding for Seaside Sparrow nests—but the upside is that protecting them from predators could also mitigate the worst effects of climate change.
