Listening to
the Cranes

Thirty-seven years of African crane sightings, turned into sound. Each year becomes a note: its pitch is how many cranes were logged, its loudness is how fast the count grew, and the gaps in the record turn to noise. Press play and watch the signal move.

The listening station

One continuous 20-second pass from 1978 to 2014. Sparse early years sit quiet and low; the two collection booms ring out bright and loud; missing years break into noise.

How a number becomes a sound

FOUR RULES MAP THE DATA ONTO THE AUDIO

Steady trend

Smooth

Calm, stable years play as a clean, even tone.

Fast growth

Louder

The faster the count climbs, the louder the note rings.

Unstable

High & shimmer

Volatile stretches add vibrato and a bright octave above.

Drop / missing

Noise

A sharp fall crackles; a missing year breaks into pure noise.

About the data. The annual curve here is a documented-profile reconstruction of the EWT African Crane Conservation Programme sightings: it reproduces the dataset's published shape — 26,403 sightings over 1978–2014, two collection booms (1994–1996 and 2008–2012), a full-time South African programme from 1994, sparse early years, and the missing-locality gaps — rather than record-level counts, which were not retrievable in this environment. Swap in GBIF's per-year facet counts and every chart and the audio regenerate unchanged.
