I decided to paint a aceo version of this lovely little hummingbird.
Calliope Hummingbirds are found in the United States and Canada and winter in Central America. They measure around 7 - 10 cm in length and weigh between 2 - 3 grams.
Calliope Hummingbird measures 2.5 x 3.5 inches and is painted on 300gsm smooth Arches watercolour paper.
Many thanks to David A Mitchell for the reference photo.
