The are some outstanding birds to be seen in
spring and summer, such as the tit (Parus
caeruleus), the canary bird (Serinus canarius) or
the Spectacled Warbler (Sylvia conspicillata). On

these ecosystems throughout the year, such as the
roadman (Anthus berthelotii) or alcaudón (Lanius
meridionalis).

caused significant damage.
