Yes... sometimes.

I shoot hand held, on a monopod, on a tripod with gimbal, or with the camera and lens on a bean bag resting on a windowsill or whatever.

It depends upon the lens I'm using, how mobile I need to be, how far I'll be walking... It also depends upon the subject and how I'll be shooting them.

For example, when hiking and not wanting to haul 9 lb. of tripod and gimbal head, I'll often take a monopod. It doubles well as a "walking stick", too, when the camera isn't mounted on it. I use a monopod mostly with lenses that have tripod mounting rings (70-200, 300mm, 100-400mm, 500mm... also macro 100mm and 180mm).

For birds in flight, I mostly shoot hand held (2 to 3 lb. 70-200, 3 lb. 300mm f/4, 3.5 lb. 100-400mm).

When shooting from a blind and spending a lot of time sitting and waiting, I usually put the gear on a tripod (especially with 6 lb. 300mm f/2.8, 8 lb. 500mm f/4, possibly with 1.4X or 2X teleconverter... but also sometimes with 100-400, 300mm f/4 and 70-200).

Shooting from a car or while lying prone on the ground, I often use a bean bag (any lens/camera combo). In fact, I leave a beanbag in my car, along with one of my monopods.

Tripod w/gimbal (500mm and 500mm w/1.4X):

98% tripod with 300mm f2.8 and a few teleconverters. I have a Wimberly gimbal mount. The feather details and not having to support a lens when I want to put it down are great reasons for a tripod. The monopod has to be supported. The gimbal mount makes the whole thing work very well. Yes I can get good shots hand held down to 1/200 sec with it at 600mm f5.6 but it's always going to be better, much better with a good tripod. Flight shots are better for me with a tripod. I have a carbon monopod that does not get any love. My usual hike is between 2 and 3 miles and at 67 I'm really really lucky I can still lug that stuff around like I do. Carry it on my shoulder. I maintain that no matter how good IBIS and IS is I'm still going to get a better picture with a tripod. YMMV and most of my friends don't carry one.
