AI sound analysis finds a rare woodpecker in Sussex woods

BBC reports that AI processing of over 1,300 hours of field recordings found the lesser spotted woodpecker's call four times on the Gravetye Estate, the first local record in over 30 years.

  • 2 for an organization

    The estate learned that a red-listed bird was present after 30 years without a record and changed its woodland management.

  • Not rated society

    Whether the woodpeckers benefit from the management change is not yet documented.

Depth runs from 1, a convenience or time saved, to 5, a life or a livelihood preserved.

Size

No magnitude yet: distribution is not documented.

The system’s part
Not isolated. The AI software found the candidate calls in recordings that the project's lead ecologist described as practically impossible to analyze by hand, and ornithologists confirmed them. The reports do not say how many candidate calls the software flagged or how many were false, and they do not name the software or show that it learns from data.

    For both birds and bats, we're passively recording the sounds of nature near our monitoring sites and using AI software, with verification, to identify species by their calls and songs.

Details

AI system

Workflow

37 acoustic monitoring stations across Sussex recorded every 10 minutes through the year. AI software screened the recordings for species calls and ornithologists verified the candidate calls.

Follow-up

Conditions for replication

Recordings must cover the breeding season, when the birds call. Experts must verify the candidate calls before a record is accepted.

Entry details

Sector

Conservation and biodiversity.

Purpose

The University of Sussex ecologists run AI software over recordings from their Nature Sense monitoring stations to identify bird and bat species by their calls, with human verification.
