Nice one - great birds! Look out for more as they (and Iberian Chiffchaff) are starting to move and half way through August into September they can be rather numerous some days. Bonelli's do breed in small numbers not so far from you near Grandola and Santiago do Cacem. Not had my first migrant Bonelli's this year yet on the southwest Portuguese coast but its iminent - just Nightingale and Iberian Chiffchaff so far.
