The reed cormorant (Microcarbo africanus), also known as the long-tailed cormorant, is a bird in the cormorant family Phalacrocoracidae. It breeds in much of Africa south of the Sahara, and Madagascar. It is resident but undertakes some seasonal movements.
The reed cormorant was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it in the genus Pelecanus and coined the binomial name Pelecanus africanus. Gmelin based his description on the "African shag" that had been described in 1785 by the English ornithologist John Latham in his book A General Synopsis of Birds. The reed cormorant is now one of five small cormorants placed in the genus Microcarbo that was introduced in 1856 by the French naturalist Charles Lucien Bonaparte.
Two subspecies are recognised: It is mainly black, glossed green, in the breeding season... Wikipedia →

Likely
About 60% of wildlife watchers report a Long-tailed Cormorant sighting in Brazzaville on a given day, based on 49 verified sightings from GBIF citizen-science data. It is the 15th most-seen of the 82 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
March and April
In those months about 70% of wildlife watchers report a Long-tailed Cormorant in Brazzaville on a given day, against about 40% in January and August, the lowest months. Those are among Brazzaville's wettest months, with about 210 mm of rain a month against almost none in July. June has too few records to rate.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Long-tailed Cormorant sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 28 cities where we can rate Long-tailed Cormorant sightings, Brazzaville ranks 3rd at about 60%, level with the leaders once rounded. The best odds are in Zanzibar City (Tanzania, about 60%) and Accra (Ghana, about 60%).
GBIF citizen-science records
It is estimated from how often the Long-tailed Cormorant is recorded against all the birds logged in Brazzaville (49 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.
