Remarks (Fish Crow may be distinguished)
The Fish Crow may be distinguished from the common Crow (1) by its much smaller size. (2) By the uniform and somewhat richer color of the back. In americanus the feathers of the back have dull tips; when the freshly-plumaged bird is held between the observer and the light these tips give the back a ringed or slightly scaled appearance. In ossifragus these tips are wanting, and the back is uniformly colored. (3) By the brighter color of the under parts. In americanus the under parts are generally much duller than the upper parts; in ossifragus they are nearly as bright.
