Christman & Co. 1962 Journal 24 June Strawberry Creek 3,000 ft. Sierra Range White Pine Grove. The stream 15 yds from the tent. It was bicolor and disappeared at the base of a willow. After dinner at 6:30 p.m. I called everyone's attention to two which were romping in the litter of aspen leaves and forbs (up to 1' high). We watched them move 30 ft. down stream playing before they disappeared in tall grass on the edge of the riparian grace [which is on the edge of a large sage area]. I threw the skimmed carcass of a Larica in the area where they were seen & work put the but end of a spooled line in the same area. Half an hour later another one came from a rock pile 10 ft. from the line to the dead & began eating it. For 5 minutes it ate then wandered around before finding the bone it ate on the line for several minutes. Then it went to the same willow near the stream & disappeared - two minutes later the same one or another came running over the same trails of the former route to the dead & bone. It appeared that this individual followed the former trail. At then ran down a stairs & we ran after it but it disappeared. All of these weasels which we observed - except the first one were immature about 1 ft. long - a deep honey color and no bicolor in evidence. The face is a light brown & blends well with the backs color. Thus no facial marking - tip of tail is black. We have concluded that there are immature weasels & are planning to trap them.
