Madeiran with a deeply forked tail (possible in some individuals given that an overlap exists with Monteiro's). I do not think that it is an early fledged (i.e., around mid-August) juvenile Monteiro's because I do not think that the plumage would not have bleached so much (from sooty black to chocolate brown) in 2-3 weeks (however, I may be totally wrong given that I do not know how much time is necessary for the plumage to bleach).
