Though the exploration and cataloging stages of ornithology are now virtually complete, new species and undescribed subspecies of birds are still occasionally discovered. In this manual, Emmet R. Blake has drawn on his experience of forty-eight years in the field and laboratory to prepare a comprehensive, detailed, and authoritative synopsis of the avifauna of tropical America as now known.L. 400-460 mm. Sexes alike. Adult: Decidedly variable. General coloration above light to dark olivaceous brown or yellowish olive, more or less heavily barred ... Caribbean lowlands of GUATEMALA (west to Baja Vera Paz) and HONDURAS.
