🗓️ Seasonal Presence iClassification Guide:
• Year-round: Detected across 9+ months
• Seasonal: Detected across 3-8 months
• Transient: Detected <3 months

Data Accuracy Disclaimer:
These classifications may be inaccurate if the station has been running for less than a full year, as it lacks seasonal historical context.

Bar height is expected frequency. Purple highlights are actual detections.
