I really love the pose of this little guy.
Boreal Chickadee's are found in Canada and Northern United States. They measure between 12.5 - 14.5 cm in length and weigh between 7 - 12.4 grams.
Boreal Chickadee 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.
