🌿 Field Note No. 60 is now live.
This spring, a pied flycatcher returned to a Finnish forest on a schedule its body has kept for thousands of years. The forest had subtly changed the schedule.
Across Finland, more than 300,000 phones have become part of a remarkable citizen-science experiment. They are listening for the arrival of migratory birds, helping researchers map spring in near real time and revealing how seasonal rhythms are beginning to shift.
In this week's edition of The Naturalist's Field Notes, I explore what a small black-and-white bird, a national listening network, and a concept from machine learning called distribution shift can teach us about a changing world.
At its heart, this is a story about observation.
About listening closely to notice when long-familiar patterns begin to drift.
And about how artificial intelligence, when placed in the service of ecology, can help us become better naturalists.
📖 If you enjoy thoughtful writing at the meeting place of ecology, technology, and the regenerative future, I invite you to subscribe to The Naturalist's Field Notes.
