It is fairly certain in my mind that
there is a marked weakening of
the attachment of the feather/feathers
in shedding some period in advance
of this process.
If not subjected to any stresses
the feathers remain intact and
come out in a regular order - at
least as concerns the longer wing
& tail feathers. Irregularity is easily
perceived known by any slight
commercial disturbance of the feathers
during the period of the solation
of the attachment. This applying

numerous shedding in order noted
when trying to establish the detailed
course of the molt.
