Nesting of Pine Siskin in Santa Cruz Co., Cal.
June 11, 1902, A. G. Vrooman took a set of pine siskin (Spinus pinus) six miles from Santa Cruz. Eggs were four, slightly incubated. The nest was sixty feet up in a pine tree and eighteen feet out from the trunk on the end of a limb; composed of weed twigs, strips of soft bark, and moss and lined with the body hair of cattle or horses. The eggs were taken with a small dip net on the end of a fishing rod. Several other pairs of birds bred in the same grove.
