Why am I seeing this?

Inputs used

The sort field you picked (observations, species, or recent activity)
Country filter (your profile country, or the one in the URL)
Taxon filter (when set, only observers active in that group count)
Approximate centroid (only when "Nearby" is on and you are signed in)

Time window

Last 30 days for activity-based sorts (7-day option also available)

Inputs used

Public sync timestamp (most recent first)
Public visibility (private observations are excluded)
No engagement signals — order does not depend on likes, IDs, or follows

Time window

All public observations, paginated 20 at a time

Inputs used

Most-recent public observation timestamp per species
Species with at least one public observation are included
Filter chips you have set (kingdom, conservation, endemic, etc.)

Time window

All-time pool, but the order key is the latest observation date

Inputs used

Rarity bucket of each missing species (rare → common)
Region pool for your country (your profile country, set in Edit profile)
Your existing pokédex (only species you have NOT yet observed are included)
No personalisation beyond country — same pool regardless of who is signed in

Time window

Snapshot of the current region pool — refreshed when the page loads

Inputs used

Approximate location (geohash-5 cell, ≈ ±2.4 km) of the photo or your device
Current calendar month (seasonality)
Count of wild public community observations matching that cell + month, descending
Distance to the closest matching observation (tiebreaker)
No model, no curated baseline — these are real community sightings only
Filtered to establishment_means = wild — excludes cultivated plants and captive/domestic animals
Filter toggle: "New to me only" — hides species already in the user's dex (has_observed_by_viewer)

Time window

Wild public observations within the same geohash-5 cell, in the current month, all years

Inputs used

Cohort definition: users with ≥ 5 observations in the last 90 days, country MX
Your four metrics: Shannon diversity, distinct habitats, validations cast, geographic spread (km²)
Each percentile is your rank within the cohort for that one metric
Hidden when the cohort is too small (n < 50) — no rank shown until the comparison is meaningful
No public leaderboard — these numbers never leave your screen

Time window

Last 90 days for the cohort; metrics are recomputed on each page visit

Inputs used

Country code from your profile (or inferred from your most-used region)
Distinct count of observers who synced ≥ 1 public observation since 00:00 UTC today
Aggregate only — no observer IDs, names, or locations are surfaced
Banner is hidden entirely when no profile country is set (never shows "in NULL")

Time window

Today (UTC) — resets at 00:00 UTC each day

Inputs used

Sync timestamp (most recent first)
Country code from your profile (used to scope to nearby observers)
Public visibility (private observations are excluded)
No engagement signals — order does not depend on likes, IDs, or follows

Time window

Top 3 most recent synced public observations
