hi luka,

45BH - michahellis
47BH - cachinnans. edit: this could well be a michahellis with some cach features: white head, whitish underwing, strong venetian blind pattern, a few narrow parallel transversal bars basal to the black tail band. but the bill and head shape looks very mich like!

just my opinion,
