The lesser cuckoo (Cuculus poliocephalus) is a species of cuckoo in the family Cuculidae. It is native to East Asia and the Himalayas; it winters to East Africa and Sri Lanka. In Japan, the bird is called hototogisu (ホトトギス/杜鵑) and frequently praised in senryu for its song.
It has been celebrated by numerous waka poets since the anthology Kokin wakashū (920). Sei Shōnagon in her essay The Pillow Book (1002) mentions a trip she and other courtiers mounted on just to hear this bird, and it was expected of them that they would compose poetry on the occasion. It is also the central image in poem 81 by Tokudaiji Sanesada in the anthology of 100 poems, the Hyakunin Isshu.
The Japanese haiku magazine Hototogisu takes its name from the bird, and the magazine's mastermind Masaoka Shiki's adopted pen name, Shiki (子規) also refers to the lesser cuckoo; shiki corresponds to the Chinese zǐguī (子規), which is an alias for its standard name dùjuān (杜鵑).
In Chinese, dùjuān is a generic name and the species' common name is xiāodùjuān (小杜鵑). In Korean literature, the song of the lesser cuckoo represents the sound of sadness. Wikipedia →

Rare
Under 5% of wildlife watchers report a Lesser Cuckoo sighting in Suzhou on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 146th most-seen of the 171 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
June and July
In those months about 10% of wildlife watchers report a Lesser Cuckoo in Suzhou on a given day, against under 5% in August to May, the lowest months. Those are among Suzhou's wettest months, with about 180 mm of rain a month against 45 mm in December.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Lesser Cuckoo sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 11 cities where we can rate Lesser Cuckoo sightings, Suzhou ranks 5th at under 5%, level with the leaders once rounded. The best odds are in Sendai (Japan, under 5%), Hangzhou (China, under 5%) and Kolkata (India, under 5%).
GBIF citizen-science records
It is estimated from how often the Lesser Cuckoo is recorded against all the birds logged in Suzhou (11 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
