What are some other weird things birds have built nests from?
A. A Warbling Vireo in California built its nest entirely of facial tissue. Chihuahuan Ravens occasionally build their nests entirely of barbed wire. A Ruby-throated Hummingbird on Long Island, New York, built its nest entirely of fiberglass roofing insulation. A Carolina Wren constructed a nest mostly of hairpins. Double-crested Cormorants off the coast of Labrador salvaged from a sunken trading vessel pocketknives, pipes, hairpins, and combs to construct their nests. A Canyon Wren in Fresno, California, constructed its nest on the beam of an office building. The nest was made entirely of office supplies including paper clips, pins, rubber bands, thumbtacks, shoelaces, needles, wire, matches, and toothpicks; it weighed 2.5 pounds.
