In BCF, the Madagascar bird is understood to lie >below< _Archaeopteryx_ on
the avian cladogram, a volant deinonychosaur descended from the (no less
volant) common ancestor of deinonychosaurs and birds. Both deinonychosaurs
and _Archaeopteryx_ had long tails, so it's no surprise that the Mad-bird had
one, too.
