Bright snow and northern lights lit up Helsinki over winter. Different owls, woodpeckers, crossbills and other northbound specialties show up randomly over cold breezes, turning outings harsh but rewarding.

Summer season brings an array of specialties to Helsinki, including broad-billed sandpiper and common rosefinch in Viikki, red-breasted flycatcher in Haltiala and stakeouts of Blyth’s reed warbler and river warbler.
