Circumstances sometimes prevent getting close for closeups. On occasions when I don't want to wade into the water, or climb the trees, long (telephoto) lenses can save the day. Of courrse, you still have to be within a reasonable distance. For today's image, I still had to get down close to the muddy shore. On this day, I wasn't prepared for wading. Although I'm not shy about doing that. These days my wife makes me wash my own clothes when I get back from outings. Some of my jeans have permanent brown legs.
