This or That?
Natural Resources Agent
Is it a turkey vulture or a black vulture? A slash pine or a longleaf pine? A saw palmetto or a cabbage palm? Identifying things in nature is not easy, but there are many ways you can learn and remember what is what. Each person remembers the name of certain species in different ways. For example, my trick to remembering a black vulture versus a turkey vulture is by the color variation of their wings when in flight. The black vulture has lighter colored feathers at the tip of its wings (Figure 1) and I remembered this by associating it with a “black-tip” shark. For the turkey vulture, the lighter color of the underside of their wings highlights a “T” shape which can easily be associated with a “t” for turkey vulture (Figure 2).
Okay, so now you’re a pro at telling the difference between a turkey vulture and a black vulture, right? What about all of the plants? Could you tell the difference between a young cabbage palm and a saw palmetto? One way cabbage palm (Sabal palmetto), our state tree, can be distinguished from the saw palmetto (Serenoa repens) is by its leaf structure. The cabbage palm has a costa which is a long, narrow, triangular extension of the petiole or what some might refer to as the “stem” (Figure 1) whereas the saw palmettos lack a costa (Figure 2). There are many other ways to tell the two apart, but remembering some key distinguishing features is very helpful in identification.
