Boulder Naturalists Ruth Carole Cushman and Pete Ruprecht beat the crowds at Rocky Mountain National Park by heading in before 9 AM, to take Trail Ridge Road up and down, to see the beautiful gold and russet hues of the parks Subalpine Meadows, surrounded by stately fir trees and limber pine.
Near sparkling blue glacial lakes known as "tarns," birds are plentiful, including a flock of borwn pine siskins that sport gold lightning stripes, and a sky blue bluebird, and a grey relative of the crow, known as the Clark's Nutcracker.
This elegant looking bird has a loud and raccous call. It lives off the seeds of evergreen trees and can hold 50 seeds in its mouth at once, while for a place to cache them in the ground for its winter food. Sometimes a Clark's Nutcracker forgets where it stored a few of those seeds, and maybe one will become a fir tree someday!
