Taxidermy: A Cased Pair of Oilbirds (Steatornis caripensis), circa 1900-1914, by Rowland Ward, The Gallery of Natural History and Artistic Treatment, 167 Piccadilly, London, a superb pair of full mount adult Oilbirds, both perched upon a painted faux rock ledge, above painted rockwork beneath, set against a simulated cave wall back drop, enclosed within a typical four-glass display case, 51.5cm by 31cm by 67cm, bearing taxidermist's partial paper trade label to verso.

The Oilbird locally known as the guácharo is a bird species found in the northern areas of South America including the Caribbean island of Trinidad, nesting in colonies within caves, oilbirds are nocturnal feeders on the fruits of oil palm and tropical laurels. They are the only nocturnal flying fruit-eating birds in the World (the Kakapo, also nocturnal, is flightless). They forage at night, with specially adapted eyesight. However they navigate by echolocation in the same way as bats, one of the few birds to do so. They produce a high-pitched clicking sound of around 2 khz that is audible to humans.
