Stretching those tiny wing muscles.
The wing muscles are growing along with the rest of the body.
A gosling has better balance when running when its wing muscles are extended.
(A parent called and the whole crew came running!)
A different view of the wings above.
A gosling appears to be doing the chicken dance.
At the edges of the wing are the beginning stems (bluish color) of the flight feathers.
The adult goose on the left has flight feathers which completely cover its white and brown tail end which is still visible on the goslings.
Close view of the new flight feathers emerging from the feather shafts.
Lots of growing required before these wings can lift this gosling.
Feathers have begun growing.
The new feathers grow from blue shafts.
Nearly a month later the feathers have grown significantly, but are still only about half the size of adult feathers.
