Utah Gray Partridges in a Spruce tree

Greetings all!   No pear tree, but. . .  Seen through a cloud of thick gray fog this morning, 10 Gray Partridges were huddled underneath a Blue Spruce tree in the back yard.  As the fog lifted, they ventured out to feed in the snow.  The lone male has large dark patches on his breast; the females' breasts are gray and white.  The rusty heads and barred sides are similar in both sexes.  This is probably the same family that I observed in the area over the summer; their numbers are reduced from 13, but I never observed a male with them.  Gray Partridges were imported from Europe; I've heard them referred to as "Hungarian Partridges."   The bird feeders are now up, but we've observed only two goldfinches taking advantage of the free provisions.
