This one was rather fun to paint - love its markings.
Harris's Sparrows are found in North America. They measure between 17 - 20 cm in length and weigh between 26 - 49 grams. This one is non breeding male. A breeding male would have more grey / black face as opposed to a buffy face.
Harris's Sparrow measures 2.5 x 3.5 inches and is painted on 300gsm Arches Watercolour paper.
Many thanks to Andy Reago & Chrissy McClarren for the reference photo.
