Bridled Titmouse look to me like a mashup of the adorable tufted titmouse and a chickadee! They are fairly common in parts of New Mexico and Arizona as well as south of the border in Mexico. They like to eat insects and acorns but if you live there keep an eye out because they will visit bird feeders too.
The painting measures 5" x 7" and will arrive in an archival sleeve with a certificate of authenticity ready for framing and display. (The mat shown in the product photo is for illustrative purposes only and is not included with the purchase.)
