Coloration: its coloration is similar to that of A. hyacinthinus, but it is significantly smaller in size. The difference between the two species lies in the tone of the colors: the head and the neck have a greenish blue coloration, the chest is a faded blue color, and the wings and tail are a tone of cobalt blue. They have a light yellow ring around the eye, with white or light bluish eyelashes. The most significant difference is in the form of the wattle (the skin around the jaw). In A. hyacinthinus it is in the form of a strip, while in A. leari it is shaped like a blot (drop).
