Finch and Wagtail Notes
All featured species are ‘Red List 2019’ assessed as ‘Least Concern’. Old World sparrows inhabit the Palearctic and Afrotropic ecoregions. Finches populate most regions of the world except for Australasia, although there are some introduced resident species in this region. Wagtails are mostly African or Eurasian species with a few in the Americas.
Euphonia part of the finch family but only found in South America. I photographed a couple of finch species in New Zealand where they seem to be more numerous than some indigenous birds. Apart from the goldfinch, the other displayed species exhibit plumage dimorphism.
