<p>The distribution of the Lesser Cuckoo Cuculus poliocephalus in Hokkaido was investigated from late April to early July, 1976–2016. Surveys were mainly conducted by 2-km-long line transect censusing in 993 quadrats (4.5 km×5 km). In addition, for 526 quadrats, census results obtained from the literature and spot censuses concerning the presence or absence of birds were also incorporated. The Lesser Cuckoo was distributed mainly in Hiyama and Oshima districts and the central part of Iburi district. These results indicate the Lesser Cuckoo to be a common summer visitor in these areas, and an irregular visitor in other areas in Hokkaido.</p>
