Laurisilva is a unique type of subtropical rainforest found in few areas of Europe and the world: in the Azores, and in particular on the island of Madeira, there are large forests of endemic Laurisilva forests (the latter protected as a natural heritage preserve). There are several species of diverse mammalian fauna, including the fox, badger, iberian lynx, iberian wolf, wild goat (Capra pyrenaica), wild cat (Felis silvestris), hare, weasel, polecat, chameleon, mongoose, civet, brown bear[citation needed] (spotted near Rio Minho, close to Peneda-Gerês) and many others. Portugal is an important stopover for migratory birds, in places such as Cape St. Vincent or the Monchique mountains, where thousands of birds cross from Europe to Africa during the autumn or in the spring (return migration).
