Cluster · quiet-grunts
Quiet grunts.
Low-amplitude, close-range grunts used in affiliative and parent-offspring contexts. Subtle; only the new wearable-logger studies recover them at scale.

AI interpretation · Quiet grunts
The hardest crow vocalization to record is the one most often used. Quiet grunts are low-amplitude, close-range, traded between paired birds and between parents and offspring. Until the new generation of wearable bioacoustic loggers came along, almost no field study captured them at scale. The 2026 Demartsev paper on carrion crows finally surfaced them; American crow studies are catching up. Our v1 corpus doesn't yet include quiet-grunt exemplars — publicly-available CC-licensed recordings are heavily biased toward what humans can hear from twenty meters away. This cluster sits on the map as a placeholder for what we know exists, but haven't yet sourced.

Our v1 CC-licensed corpus doesn't yet include exemplars for this cluster. The embedding space tells us where the cluster lives geometrically; the audio will follow as we expand the public corpus. Contributors welcome.
