The Cape gannet (Morus capensis) is a large seabird of the gannet family, Sulidae. They are easily identified by their large size, black and white plumage and distinctive yellow crown and hindneck. The pale blue bill is pointed with fine serrations near the tip; perhaps because of the depth and speed of the gannet's dive when fishing (depending on altitude, gannets hit the water at speeds of between 40 and 86 km/h (25 and 53 mph)), its beak has no external nostrils into which the water might be forced. The widely mentioned maximum speed of 120 km/h has never been measured and published.
German naturalist Hinrich Lichtenstein described the Cape gannet in 1823. The Sulidae, the gannets and boobies, appeared about 30 million years ago. Early Sulidae fossils most resembled the boobies, although they were more aquatic, with the gannets splitting off later, about 16 million years ago. The gannets evolved in the northern hemisphere, later colonising the southern oceans. The most ancient extant species may be the Abbott's booby, possibly the sole survivor of an otherwise extinct separate lineage. A 2011 genetic study of nuclear and mitochondrial DNA suggests that the ancestor... Wikipedia →

Rare
Under 5% of wildlife watchers report a Cape Gannet sighting in Durban on a given day, based on 28 verified sightings from GBIF citizen-science data. It is the 134th most-seen of the 219 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
June and August
In those months about 10% of wildlife watchers report a Cape Gannet in Durban on a given day, against under 5% in July and September–May, the lowest months. Those are among Durban's driest months, with about 35 mm of rain a month against 210 mm in January.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Cape Gannet 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 Cape Gannet sightings: under 5% of wildlife watchers there report one on a given day.
Same order: Suliformes
The closest relatives of the Cape Gannet that you can see in Durban (order Suliformes, Gannets, Cormorants, and Allies) are Great Cormorant (about 10%) and Long-tailed Cormorant (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Cape Gannet is recorded against all the birds logged in Durban (28 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.
