A fresh installation of Audacity isn’t optimised for scanning nocmig recordings, but with some simple tweaks it can be ready on demand. 

This is interesting. I’ve been dabbling in bird song with Merlin recently. I didn’t know you could use Audacity to see audio as a Spectrogram. This post shows how.

I’ve only just head of nocmig.

The nocturnal equivalent of visible migration watching, and typically employs sound recording equipment to capture the flight calls of migrating birds.

Read ‘Sometimes I wonder if I’ll come back’: Palestinian birdwatchers defy danger to scan the skies by Guardian staff reporter
Gathering on a wooded hilltop overlooking terraces of olive trees and vineyards, a group of ninth-grade girls from the Aida refugee camp watch as Michael Farhoud, a researcher at the Environmental Education Centre (EEC) in Beit Jala, attaches a ring to the leg of a chiffchaff. The tiny olive-brown warbler was caught in nets that morning. Farhoud explains to the schoolgirls how ringing tracks birds' movements.

I saw a chiffchaff or willow warbler with a ring the other day. I wonder if it had passed through Palestine.

Walked to Loch Humphrey this morn. Warm, cloudy a slight breeze. The ground sparkling with flowers. Meadowsweet coming out. Plenty of birds too. Whitethroat singing in the new trees. A skylark bathing in the path dust. Butterflies: Meadow Browns, Ringlets & a Small pearl-bordered Fritillary.
