Extensive Definition
Fledge is the stage in a young bird's life when the feathers and
wing muscles are sufficiently developed for flight. It also
describes the act of raising chicks to a fully grown state by
the chick's parents.
In ornithology, the meaning of
fledging is variable, depending on species. Birds are sometimes
considered fledged once they leave the nest, even if
they still can't fly. Some definitions of fledge take it to mean
the independence of the chick from the adults, as adults will often
continue to feed the chick after it has left the nest and is able
to fly.
One notable species, the Ancient
Murrelet, fledges two days after hatching, running from its
burrow to the ocean and
its calling parents. Once it reaches the ocean it is cared for
several weeks by its parents. Other species, such as Guillemots and
some cormorants leave
the nesting site before they are able to fly, or barely able to
fly. The fledging behaviour of the guillemot is spectacular; the
adult will lead the chick through the colony if possible, for large
drops like cliffs, it will fly down and call to its young. The
chick will then launch itself off the cliff, attempting to fly as
far as possible, crash landing on the ground below before
continuing its run towards the ocean.
