Seabird Phenology — Species × Month, Mangaluru Pelagic (2011–2025)
All 47 true pelagic/seabird taxa, grouped by family, against every calendar month. Each cell's color intensity is that species' own abundance in that month, scaled against its own yearly maximum — so a rare species' real peak still shows up clearly, rather than being washed out by species like Wilson's Storm-Petrel that vastly outnumber everything else.
Abundance by species and month
Hover any cell for the exact count, survey coverage and % detection for that species that month. Hatched cells = month never surveyed (Jun–Aug). A faint cell = surveyed, species not recorded. Rows are sorted by total individuals within each family group.
Color is row-normalized (each species scaled 0–100% of its own peak month), not a shared scale across species — use the numbers in the tooltip, not cell-to-cell color, to compare abundance between different species.
