The plaintive cuckoo (Cacomantis merulinus) is a species of bird belonging to the genus Cacomantis in the cuckoo family Cuculidae. It is native to Asia, from India, Nepal and China to Indonesia. The plaintive cuckoo is fairly small, measuring about 21–24 cm (8.3–9.4 in) long. The adult male is grey-brown above and orange below with a grey head, throat and upper breast. The tail feathers have white tips. The legs and feet are yellow, the eye is red and the bill is black above and yellow below. The adult female is sometimes similar to the male but often occurs in a "hepatic" morph. This form is reddish-brown above with dark bars. The underparts are paler with fainter barring. There is a pale stripe over the eye and the tail has dark bars along its whole length. Juvenile birds are similar to hepatic females but are paler and have dark streaks rather than bars on the crown and throat.
The male has several plaintive whistling calls. These include an ascending series of three-note phrases and a series of 11 or 12 descending notes. There are four subspecies. The nominate form C. m. merulinus is found in the Philippines where it is common... Wikipedia →

Rare
Under 5% of wildlife watchers report a Plaintive Cuckoo sighting in Tuen Mun on a given day, based on 44 verified sightings from GBIF citizen-science data. It is the 109th most-seen of the 183 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
March, May and August
In those months about 10% of wildlife watchers report a Plaintive Cuckoo in Tuen Mun on a given day, against under 5% in April, June–July and September–February, the lowest months. Those are among Tuen Mun's wettest months, with about 180 mm of rain a month against 20 mm in December.

GBIF citizen-science records
It is estimated from how often the Plaintive Cuckoo is recorded against all the birds logged in Tuen Mun (44 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.
