Use of Rocks in Say Phoebe's Nest
Use of Rocks in Say Phoebe’s Nest.- On April 12, 1942, a nest of the Say Phoebe was found on a rocky cliff in a canyon of the Virginia Range east of Reno, Nevada. The nest was situated on a narrow horizontal shelf which sloped downward. Perhaps to prevent slipping on this shelf, tbe whole outer base of the nest was formed of small angular rocks (weathered veined quarts), averaging about an inch in length and 2 1/2 to 3 grams in weight. The upper and inner parts of the nest were beii finished at this time, chiefly with wool apparently gathered from bushes where tufts of it had been caught from sheep passing through the area. When the accompanying photograph (fig. 65) was taken on May 10, the nest was finished and contained eggs.- Nevada, May 17,1942.
