The fauna of Portugal is a mixture of European and North African types. As in Spain, the wild goat, wild pig, and deer can be found in the countryside. The wolf survives in the remote parts of the far north and northeast, and the lynx inhabits the Malcata Mountains. The fox, rabbit, and Iberian hare are ubiquitous. Birdlife is rich because the peninsula lies on the winter migration route of western and central European species. Hunting zones cover nearly one-third of Portugal. In the Azores, only the smaller mammals are found—such as the rabbit, weasel, ferret, rat (brown and black), and mouse as well as various types of bats. Game birds include woodcock, red partridge, quail, and snipe. The highly endangered Mediterranean monk seal is native to Madeira’s Desertas Islands, which were designated a nature reserve in 1990. Some 40 species of birds breed
there, including the Madeira laurel pigeon and the Zino’s petrel. The variety of beetles (nearly 700 species, many indigenous) and moths (more than 100 species, about one-fourth of which are peculiar to the Madeiras) is remarkable. Fish are plentiful in the Atlantic waters of mainland Portugal, especially the European sardine. Crustaceans are common on the northern rocky coasts, and clams and oysters are raised in the Algarve. Larger fish (tunny, bonito) as well as mullet are caught off the Azores and the Madeira Islands
