Peak week unresolved in the current model. Regular arrival unresolved; use individual seasonal records. Regular departure unresolved; use individual seasonal records. Skulking species: habitat and vocal detection are often more useful than visual scanning. Timing is based on extremely sparse local data; treat the dates as an alert window rather than a stable seasonal curve.
