Synchronized Swimming, 2019, Oil on Board, 12"x24"
Upon returning to direct application of paint, I lightened the blue and eliminated the orange band behind the birds as I didn't feel there was adequate contrast.
Cornell University's ornithology lab is a great resource of information about birds. They say the following of the Carolina Wren.
Unlike other wren species in its genus, only the male Carolina Wren sings the loud song. In other species, such as the Stripe-breasted Wren of Central America, both members of a pair sing together. The male and female sing different parts, and usually interweave their songs such that they sound like a single bird singing.
One captive male Carolina Wren sang nearly 3,000 times in a single day.
A pair bond may form between a male and a female at any time of the year, and the pair will stay together for life. Members of a pair stay together on their territory year-round, and forage and move around the territory together.
The oldest recorded Carolina Wren was at least 7 years, 8 months old when it was recaptured and rereleased during banding operations in Florida in 2004. It had been banded in the same state in 1997.
