About this data
Source-verified months inform the seasonal filters. Local timing can vary. Unconfirmed months do not imply absence. Presence verification is separate from monthly status; each month's details identify its verification. Lighter bands mark estimated timing. Empty event rows mean no event is recorded, not confirmed absence.
