I thought "tear drop shaped pubes" was an accurate description, and a
nice turn of phrase.  But I do have reservations about this feature
having a role in flight evolution.  There's a great many changes
evident in the skeletons of theropods on the line that led to birds.
Sometimes it's not clear which of those changes can be directly linked
to aerial locomotion.
