In an extraordinary event for ornithology enthusiasts in Finland, an eastern cuckoo has been observed for only the second time in the country's history. This rare species was discovered last summer in Kuhmo by keen nature photographers Arsi Ikonen, Ville Heikkinen, and Markus Varesvuo. The observation was officially validated by Bird Life Finland's rarity committee last week, sparking interest among bird watchers and researchers alike.

The initial encounter with the eastern cuckoo happened by chance at Heikkinen's backyard in Kuhmo's Iivantiira area. As Ikonen was photographing a weasel, he heard an unfamiliar bird call, suspecting it might be a crested bird he had heard before in Spain, though it sounded slightly different. Following up on this lead, Heikkinen and Varesvuo returned to identify the sound more clearly, leading to the conclusion that it was indeed an eastern cuckoo.

The identification of the bird took three days of dedicated effort. On the first day, they heard the cuckoo but did not see it; the second day offered a brief audio confirmation, and it wasn't until the third day that they could positively identify the species. Such rare sightings add valuable insights to Finland’s birding records and highlight the importance of citizen science in wildlife tracking and research.
