HI Gail, when they moult they dont usually lose all feathers at the same
time. I get birds in rehab regularly that have no tail....and most times its
due to a narrow escape from a predator...who grabs them by the tail and they
drop their feathers to escape.

thanks

Helene

  Please forgive my question, as, perhaps the answer is obvious, but how in
the world are birds, that have lost their tails due to molting (I assume),
able to remain in flight without crashing into things or the ground? I
naturally thought that their tails were a necessary component for navigation
(steering) at least. I know they can fly because Bernard Burke photographed
a tailless crow flying, that is included in one of his recent web-shots.
  Thanks!
