Can we use a macro lens as a telephoto lens?

When a zoom telephoto lens says "macro" it means the lens can focus closer than a normal zoom lens. However, it cannot focus as close as a true macro/micro lens. A true macro/micro can focus as close as 1:1. The zoom lens photos will look fine, it's just that you won't be able to focus close enough to see an ant's face. Since you will be using the zoom for bird & wildlife photos, you won't need a macro because you will be focusing on objects several feet away.
