An interesting fact about this American bird is that the male only molts into the bright orange plumage in the fall of their second year. Until then the young male plumage is more yellow-orange. Another interest fact is that they seem to prefer eating ripe dark coloured fruit. You wouldn't think birds would be selective when it come to food.
Baltimore Oriole measures 3.5 x 2.5 inches and is painted on 300gsm smooth watercolour paper.
