However,
you
can
see
differences
in
wing
morphology
associated
with
 certain
types
of
flying,
and
differences
in
feeding
adaptations
based
on
food
preference.

 The
shape
of
the
wing
and
length
of
flight
feathers
allow
for
adaptations
for
different
 patterns
of
flight.
Birds
have
wings
and
muscles
adapted
for
long‐distance
flight,
short‐ distance
flapping
flight,
and
soaring
flight.
Birds
also
have
very
different
beaak
shapes
that



 are
highly
correlated
to
diet.

 Like
the
reptiles,
birds
produce
an
amniotic
egg.
Unlike
reptiles,
the
egg
of
birds
has
a
 hardened
shell.
This
rigid
covering
provides
ore
solid
protection
for
the
developing
embryo,
 and
protects
the
embryo
from
physical
damage
while
adult
birds
incubate
the
eggs.
Most
 birds
also
spend
time
and
energy
actively
incubating
their
eggs
and
providing
parental
care
 for
the
offspring
in
which
one
or
both
parents
may
feed
and
care
for
the
young.
