1. Red List Categories And Criteria

   Linked via "pheromonal signaling patterns"

   Criterion C: Small Population Size and Decline
   Criterion C is applied when a species population falls below specific numerical thresholds (e.g., fewer than 2,500 mature individuals for VU). Furthermore, it requires evidence of continuing decline, often quantified by observing a decrease in the frequency of specific pheromonal signaling patterns across breeding seasons.
   Criterion D: Very Small Population or Restricted Area
