Size and Shape:

The Kentucky Warbler is a small, stocky bird, with a length of approximately 4.5 to 5.5 inches and a wingspan ranging from 7 to 9 inches. Its body is compact, and it has a relatively large head with a short, sturdy bill, perfect for capturing insects. The Kentucky Warbler's legs are strong, allowing it to navigate and forage efficiently through dense vegetation and undergrowth.
