My new telephoto and I go to the zoo

A few weeks ago I bought a Canon 100-400mm f/4.5-5.6L telephoto (the earlier model, not the newer one that costs a thousand dollars more). I use it on my 70D, which has a crop sensor, so the range is effectively 160 - 640mm. I thought a trip to the zoo would be a good way to put it through its paces. Seattle has a great zoo in Woodland park.
In general, I like the lens. It is heavy, and focuses slowly, so I missed a few shots. I find that sometimes it is razor sharp and 400mm and sometimes a bit soft. Perhaps my technique?
Anyway, I had a lot of fun and took a surprisingly large number of photos. Here are some of my favorites.

All nice shots. I have a tamron 150-600. I keep it attached to my tripod. Its one heavy beast. Too much for this soon to be 86 year old man to handle.

I think your bird is a night crowned heron but I'm no expert, I'm one of those opinion guys. Not a lot of help I know. Hey the lemur shot is really good, so is the wolf.

Most definitely a black crowned night heron!

No the range is not 160-640. That is just an equivalent view from a full frame camera, only it is cropped. You don't have the resolution of the full frame either. While you may think you got more reach, you really did not. This comparison and equivalent views is a false marketing ploy by the manufacturers. Lost in translation many believe they are getting more range. Well, that is not true.

Take that image on a full frame camera at 400 mm and crop it and that is what you get with the crop sensor camera. Did you get out father than the full frame? No you did not. Did you exceed the 400 mm. No you did not. To do that you would need to add a TC an only if the lens accepts it.
