Observe a single day of crow activity at both Bothell and Redmond roost sites, noting timing, flight patterns, and interactions with people. Explain, in clear terms, the ecological factors that could drive a mass roost shift (food sources, predators, light, and habitat changes) and how urban landscapes influence these factors. Incorporate at least one method scientists use to study urban wildlife (e.g., tracking, citizen science, or acoustic monitoring) and imagine how residents and planners could respond humanely. Use a short, engaging narrative voice that blends local reporting with accessible science. End with a concise takeaway about what this case reveals about coexistence in growing cities.
