Nesting Cassin's Vireo (Vireo cassinii

Location: Alum Rock Park, Santa Clara County, Calif.   Date: May 7, 2005

(The nest was found in a tree next to picnic tables in a busy picnic area, where we ate lunch.)

"Nest: Placed in horizontal fork of branch in tree, often quite low (3-12 feet above ground) but can be up to 35 feet or higher. Nest (built by both sexes) is a rather bulky open cup suspended by its rim. Nest is made of grass, strips of bark, weeds, plant fibers, rootlets, lined with plant down and hair. Outside of nest may be decorated with moss, pine needles, pieces of paper." [from Lives of North American Birds by Kenn Kaufman]
