Juvenile Green-breasted Mango Hummingbird. Photography based archival fine art print. © Image copyright registered by the maker. 

Green-breasted Mango males have a green breast with a dark blue stripe which looks black when not brightly lit. Juvenile males have a buff coloration on their face, which they gradually lose as they molt into adult feathers. 

Young birds are responsible for the majority of occurrences in the United States. The first green-breasted mango documented north of Mexico was photographed in coastal Texas in September 1988. The species has since become an increasingly frequent vagrant and extremely rare resident in the lower Rio Grande Valley of southern Texas.

They are about 4 1/2 inches long and weigh 1/4 of an ounce

Prints have a one inch white border that includes the artist's signature and image number.

Mats are dark grey with a thin white reveal. They include the image number and artist's signature. Frames are mat black aluminum.
