Mystery bird


Last august/september 2011, we have had a new arrival here at Montes de Almachada. It´s a couple, about twice/three times the size of a Blackbird, black with red wing-ends, yellow beak, long quite slim body and long tail and what makes it very unusual is the sound it makes. Like a very loud motor. Sometimes there are short callings and specially in the mornings, a long loud noise.
We have spoken to all the neighbours and nobody has ever seen or heard such a bird.
Patrick and I have spent many hours on internet and gone through all the birdbooks we own, but with no result.
