raspberry juice and left out in the sun to fade. 
But only the mature males wear this colour, 
which is deepest on their head, rump, and breast.

about in flocks. You see them in the hemlock 
and spruce trees feeding on the buds at the tips 
of the branches, in the orchard pecking at the 
blossoms on the fruit trees, in the wheat fields 
with the goldfinches destroying the larvse of

October, it is still a delightful reminder of the
