A pure white feather of a Lagopus mutus passes the spring equinox,
and a feather turns molting into blackish brown from a head / neck /
chest as the daylight hours become long.
The abdomen / a foot / a wing is whole year, a white feather,
and an eye / a beak / a nail / a tail feather is black whole year.
They will make "one's territory" when they become the end of March.
In the sphere of influence that male will make, a turn lives.
Lagopus mutus does breeding and all of life in the sphere of influence.
(Make a nest, Copulation, Laying eggs, Incubation, Bring up a young bird, Eat, Rest)
A Lagopus mutus of high rank ranking can have breeding
and the sphere of influence to have on of life in good environment.
A strong Lagopus mutus will secure the better sphere of influence.
Because there is a spot of small brown light brown spots of wave design
to a black ground as for the feather of male to have a female in the breeding season,
the whole is blackish brown and can see it.
The white feather which is not replaced yet is mixed,
but nuptial coloration will disappear when territory dissolves.
