Chlorospiza (?) xanthogramma
Gould and G. R. Gray, 1839,
East Falkland Island and Tierra del Fuego.
Type description includes Falkland Is, possibly indicating misidentified immature of M. melanodera, but this considered unlikely, as morphological and ecological differences between the two species in Falklands already well described at the time; no recent records of present species from Falklands, where presumably now extirpated. Race barrosi larger and duller, with whitish vs yellowish outer tail, but song similar to that of nominate#R. Shows a peculiar polymorphism, some birds being extensively washed green above and yellow below, others not; distribution and significance of this “green morph” not well understood. Two subspecies recognized.
