Abstract
Damage to grapes by house finches (Carpodacus mexicanus) is widespread and well documented in California. DeHaven (1974) estimated that damage in nine counties exceeded 0.75 million dollars while Clark (1976) indicates a probable loss of 3.7 million dollars throughout the entire state. Crase et al. (1976) indicated that house finches undoubtedly are the principal depredating species. Various protection measures are described by Piper & Neff (1937), Boudreau (1972), and Clark (1975, 1976). Current protection programs are explained by Crabb and Martin (1977).
