† N. megacephalus
( Milne-Edwards, 1874)
We had Bitterns as big and as fat as capons. They are tamer and more easily caught than the 'gelinotes'... The lizards often serve as prey for the birds, especially for the Bitterns. When we shook them down from the branches with a pole, these birds ran up and gobbled them down in front of us, in spite of all we could do to prevent them; and even if we only pretended to do so they came in the same manner and always followed us about.
A traveler named M. Dubois, staying at the island from 1669 to 1672, described them as grey birds with white spots on each feather and green legs. However this could also refer to the dimorphic egret (Egretta dimorpha).
Behaviour and ecology
Both authors agree that this bittern-like bird, the size of a fat chicken or small egret, was mainly terrestrial, unwary, and only flew when chased, although even in that case they initially tried to escape by running. They apparently laid greenish eggs; one of their favorite foods was geckos, probably the Rodrigues day gecko as the other local species, the Rodrigues giant day gecko was nearly as long as the bird itself (both gecko species are nowadays extinct too). Analysis of the fossil remains concluded that the bill of the species was very strong (hence the name megacephalus, i.e. "large-headed") and that it was evolving towards flightlessness.
Many other species endemic to Rodrigues became extinct after humans arrived, and the island's ecosystem is heavily damaged. Before humans arrived, forests covered the island entirely, but very little remains today. The Rodrigues night heron lived alongside other recently extinct birds, such as the Rodrigues solitaire, Rodrigues parrot, Newton's parakeet, Rodrigues rail, Rodrigues owl, Rodrigues starling, and the Rodrigues pigeon. Extinct reptiles include the domed Rodrigues giant tortoise, the saddle-backed Rodrigues giant tortoise, and the Rodrigues day gecko.
