The square-tailed drongo (Dicrurus ludwigii), formerly the common square-tailed drongo, is a passerine bird in the family Dicruridae. It is a common resident breeder in parts of southern Africa. These insectivorous birds are usually found in forests or dense bush. They are aggressive and fearless birds, given their small size, at 19 cm (7.5 in), and will attack much larger species if their nest or young are threatened. The male is mainly glossy black, although the wings are duller. The female is similar but less glossy. The bill is black and heavy, and the eye is red. This species is similar to the fork-tailed drongo, but is smaller, and the shorter tail lacks the deep fork which gives the latter species its name. The fork-tailed drongo is also typically found in more open habitat. The common square-tailed drongo has short legs and sits very upright whilst perched prominently, like a shrike. It flycatches or take prey from the ground. The call is a harsh cherit-cherit. Two to three eggs are laid in a cup nest in a fork high in a tree.
The square-tailed drongo was described by the Scottish zoologist Andrew Smith in 1834 from birds observed around Port Natal (now Durban... Wikipedia →

With luck
About 10% of wildlife watchers report a Common Square-tailed Drongo sighting in Durban on a given day, based on 106 verified sightings from GBIF citizen-science data. It is the 67th most-seen of the 219 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
December
In that month about 20% of wildlife watchers report a Common Square-tailed Drongo in Durban on a given day, against about 10% in January to November, the lowest months. That is one of Durban's wettest months, with about 210 mm of rain against 25 mm in June.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Common Square-tailed Drongo sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Durban, in our data
Durban is the only city on Wallace's Line with enough records to rate Common Square-tailed Drongo sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Common Square-tailed Drongo is recorded against all the birds logged in Durban (106 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.
