live acoustic field noteBengaluru

Birds heard
from home.

A live BirdNET microphone meets old natural-history plates. Each bird has been heard at least twice; the larger the plate, the less often this microphone has heard it.

This is microphone rarity—not ecological rarity or conservation status.

Asking the microphone what it has heard…

field method

A listening log, illustrated backwards in time.

01

Listen live

BirdNET identifies calls at the microphone. New detections arrive here over a live event stream.

02

Remove one-offs

A species enters the wall only after its second detection, reducing accidental and uncertain labels.

03

Scale by rarity

Card area uses an inverse logarithmic scale across this microphone’s archive: fewer detections, more room.

04

Pair with a plate

Scientific names connect detections to open historical art. Artist, date, licence, and source travel with every image.

Artwork is served locally from open collections including Wikimedia Commons, the Biodiversity Heritage Library, Naturalis, and the National Gallery of Art. One modern open illustration stands in for the Ashy Prinia because its 1798–1805 British Library watercolor is catalogued but not digitized.
