| This rather fresh 1st.winter shows very
different
progress in molt compared with the individual on the right and these individuals in October and November. |
A very worn and faded 1st.winter, nearly 1st.summer.
Individuals like this usually appear from mid-winter to spring. |
 |
|
This another late-molt bird shows only four new 1stwinter feathers in scapulars. |
|
 |
|
These two 1st.winter birds show very different look. |
