Laurel Pigeon

The laurel pigeon is endemic to the mountainous subtropical Atlantic west Canary islands, where it occurs on the islands of La Palma, La Gomera, Tenerife and El Hierro. In the 1980s, the population was estimated at 1,200-1,480 individuals, but more recent surveys have shown that it is more numerous, and more widely distributed. The largest subpopulation is found on La Palma, where it occurs across much of the northern half of the island. The species is common on La Gomera, where it is found primarily in the north, and also occurs patchily on the northern slopes of Tenerife. It has recently also been recorded on El Hierro; however, breeding there has not yet been confirmed3,4. Although the species was recently suspected to be declining on Tenerife. Formerly also bred on the neighbouring Gran Canaria. It mainly occurs on the northern slopes of the mountains, but smaller numbers are found in the south where suitable patches of laurel forest remain. The natural habitat is tall laurisilva forest or dense tree heaths which are cloud-covered for much of the year. The forests consist mainly of Azores laurel, Oreodaphne foetens, til, Madeira mahogany, Canary laurel, faya, lily of the valley tree and the picconia. The Trocaz pigeon prefers primary forests, but secondary growth is used for feeding, and agricultural land is also visited, especially at times of fruit shortage. Most of the pigeons are found below 1000 m (3300 ft), and their prime environment appears to be steep ravine-indented slopes along artificial watercourses, with the occasional large dead laurel tree and much tree heath. This species is highly mobile between different areas at different times of year. It was very abundant when the islands were first colonised by humans, but was extirpated. The losses on the islands were largely due to deforestation for wood and to create agricultural and grazing land. The exclusion of livestock from the native forest allows it to regenerate and create more suitable habitat. Some illegal hunting and poisoning continues because of the damage this pigeon can do to crops. Perhaps the main limiting factor on the rate at which the pigeon increases its numbers is eggs and young being taken by introduced black rats. It is now classed as Near Threatened on the IUCN Red List, an improvement on its Threatened status in 1988. This species is protected under the European Union Birds Directive, and the laurel forests under the Habitats Directive.
