ABSTRACT: Since 1985, 58 species have been added to the Colorado list, 49 confirmed as new to the state, 8 to reclassification of subspecies as species, and 1 to description of a new species (the Gunnison Sage-Grouse, Centrocercus minimus). The changes include discovery of a resident population of the Ruffed Grouse (Bonasa umbellus), transitory colonization of the Inca Dove (Columbina inca), marginal colonization of the Acorn Woodpecker (Melanerpes formicivorus), the Glossy Ibis (Plegadis falcinellus) becoming a regular spring migrant, massive colonization of the Eurasian Collared-Dove (Streptopelia decaocto), vagrancy of four species of Old World origin, and vagrancy of one species of Southern Hemisphere origin, the Kelp Gull (Larus dominicanus).
