The malachite kingfisher (Corythornis cristatus) is a river kingfisher which is widely distributed in Africa south of the Sahara. It is largely resident except for seasonal climate-related movements. The malachite kingfisher was described by the German naturalist Peter Simon Pallas in 1764 and given the binomial name Alcedo cristata. The specific epithet cristata is from the Latin cristatus meaning "crested" or "plumed". The adjective "malachite" in the vernacular name normally refers to the dark green colour of the copper containing mineral. This kingfisher has blue upperparts but has black banding with pale blue or greenish-blue on its forehead.
A molecular phylogenetic study published in 2007 confirmed that the most closely related species is the Malagasy kingfisher, (Corythornis vintsioides). The Malagasy kingfisher has a black bill and greenish crest, and is not quite as dependent on water as the African species. It is otherwise similar in plumage and behaviour to the more widespread malachite kingfisher. The São Tomé kingfisher and the Príncipe kingfisher were sometimes considered as distinct species but a study published in 2008 showed that they are both subspecies... Wikipedia →

Rare
Under 5% of wildlife watchers report a Malachite Kingfisher sighting in Nairobi on a given day, based on 71 verified sightings from GBIF citizen-science data. It is the 99th most-seen of the 234 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
March, July–October and December
In those months about 10% of wildlife watchers report a Malachite Kingfisher in Nairobi on a given day, against under 5% in January–February, April–June and November, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Malachite Kingfisher sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
18th of 20
Of the 20 cities where we can rate Malachite Kingfisher sightings, Nairobi ranks 18th at under 5%. The best odds are in Mombasa (Kenya, about 60%), Kigali (Rwanda, about 30%) and Yaoundé (Cameroon, about 30%).
GBIF citizen-science records
It is estimated from how often the Malachite Kingfisher is recorded against all the birds logged in Nairobi (71 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.
