It has been observed on iNaturalist exclusively in the Açores, so it is possible that it is an endemic species, though not much is known about it.

The trocaz pigeon, Madeira laurel pigeon or long-toed pigeon is a pigeon which is endemic to the island of Madeira, Portugal. It is a mainly grey bird with a pinkish breast; its silvery neck patch and lack of white wing markings distinguish it from its close relative and probable ancestor, the common wood pigeon. Its call is a characteristic six-note cooing, weaker and lower-pitched than that of the wood pigeon. Despite its bulky, long-tailed appearance, this pigeon has a fast, direct flight.
Günther Edmund Maul was a German ichthyologist and taxidermist in Portugal. Maul came to Madeira in December 1930 to work as taxidermist at Museu Municipal do Funchal, which opened to the public in 1933. He was appointed director for the museum in 1940, a post that he held to his retirement in 1979. He, however, continued his research until shortly before his death. He started two journals and opened the museum's aquarium to the public in 1959. He also participated in several expeditions including with the French bathyscaphe Archimède in 1966 and organised the first multidisciplinary expedition to the Salvage Islands in 1963. He was awarded an honorary doctorate from the University of Madeira in 1995.
Raja, also known as raia, is a genus of skates in the family Rajidae containing 16 species. Formerly a wastebasket genus, many species historically categorized here have been moved to other genera in the family, such as Amblyraja, Beringraja, Dipturus, Leucoraja and Rostroraja. Raja are flat-bodied, cartilaginous fish with a rhombic shapes due to their large pectoral fins extending from or near from the snouts to the bases of their tails. Their sharp snouts are produced by a cranial projection of rostral cartilage. The mouth and gills are located on the underside of the body. They may be either solid-coloured or patterned, and most skates have spiny or thorn-like structures on the upper surface, while some species contain weak electrical organs within their tails. Mating typically occurs in the spring and the female lays numerous eggs per clutch which are encapsulated in leathery cases, commonly known as "mermaid’s purses". Species vary in size, ranging from about 40 to 140 cm (1.3–4.6 ft) in length. These bottom-dwellers are active during both day and night, and typically feed on molluscs, crustaceans and fish. Raja skates are found in the East Atlantic, also in the Mediterranean, and western Indian Ocean, ranging from relatively shallow water to a depth of 800 m (2,600 ft). Skates and related species have fossil records dating from the Upper Cretaceous period, thus this well-adapted species is quite ancient.
The Madeira pipistrelle is a species of vesper bat. It is endemic to Azores, Madeira and the Canary Islands.
Hipparchia maderensis, the Madeiran grayling, is a species of butterfly in the family Nymphalidae. It is endemic to Madeira. Its natural habitat is temperate forests. Seitz treats it as a race of Hipparchia semele - in maderensis Baker, from Madeira the upperside in both sexes is strongly obscured and in the male almost without any markings.
Gonepteryx maderensis, the Madeira brimstone, is a species of butterfly in the family Pieridae. It is endemic to Madeira. Its natural habitat is temperate forests. It is threatened by habitat loss.
Wollastonaria oxytropis is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Geomitridae, the hairy snails and their allies.
Sorbus maderensis is a species of rowan in the family Rosaceae that is endemic to Madeira. It is threatened by habitat loss.
The undulate ray is a species of skate and cartilaginous fish found in the Mediterranean and East Atlantic from southern Ireland and England to the Gulf of Guinea. It is found in areas with mud or sand, and may occur as deep as 200 m (660 ft), though it prefers shallower depths. It is considered endangered due to overfishing.
Dactylorhiza foliosa, the Madeira orchid or leafy orchid, is a species of flowering plant in the family Orchidaceae, endemic to the Portuguese Island of Madeira in the eastern Atlantic Ocean. It is a tuberous herbaceous perennial growing to 60 cm (24 in) and producing spikes of intense, magenta-pink flowers in late spring.
Diplodus cervinus, the zebra sea bream, is a species of marine ray-finned fish belonging to the family Sparidae, which includes the seabreams and porgies. This species is found in the temperate north eastern Atlantic Ocean and the Mediterranean Sea.
Beringraja rhina, commonly known as the longnose skate, is a species of skate in the family Rajidae from the northeast Pacific. It is found from the eastern Bering Sea and Alaska to Baja California and the Gulf of California. The longnose skate is found at depths of 9–1,069 m (30–3,507 ft) and often deeper than the big skate. The longnose skate has only recently been associated with the genus Beringraja, having been previously included in Raja until genetic evidence supported reclassification. This issue has not be completely resolved and the scientific name "Raja rhina" is still in widespread use.
The Madeira rockfish is a species of scorpionfish (Scorpaenidae) in the genus Scorpaena, found in the coastal waters of the eastern Atlantic Ocean and the Mediterranean Sea. This species reaches a length of around 14 centimetres (5.5 in) SL. The species was described by Achille Valenciennes in 1833 after a specimen from Madeira. Although S. maderensis is well represented in the areas that it is found, many key aspects of its biology are still unknown.
The Madeira evergreen forests is a laurissilva ecoregion of southwestern Europe. It covers the archipelago of Madeira and some nearby islands in the Atlantic Ocean. Laurel forest, known as Laurisilva of Madeira, once covered the islands. Over centuries the laurel forests were mostly cleared. Madeira's remaining forests are now protected.
