My last days in Helsinki are coincident with the arrival of thousands of migrant birds and the vegetation green-up. Scenic walks with friends result in European otter, red-breasted flycatcher, corn crake, and much more.

I finally managed to spot all nine owl species in Helsinki after two years, from the large and rare great gray owl to the minute Eurasian pygmy-owl. Here, I gather the stories of all these finds.

A University of Helsinki course on conservation brings me to Saimaa, the largest lake in the European Union. We find the endemic Saimaa ringed seal and learn how it is perceived by local communities.
