Diagnoza

Straighter and more craniocaudally curved femur and larger size than the Rupellornis brodkorbi.

Porównanie

Rupelornis babaheydariensis differs from R. definitus some morphological features, eg. proportionally narrower distal tarsometatarsus. Rupelornis brodkorbi is smaller and Rupelornis harmathi is larger.

Autekologia

Less adapted to gliding than most extant procellariiforms and more likely employed flap-gliding, as do extant Oceanitidae. The feet may not only have served as a brake for rapid stops when the bird caught sight of prey near the water surface but, immersed into the water, they may have also facilitated a stationary position of the flying bird at open sea.
