Capturing wild life can be a bit of a challenge. instead of going through the trouble of a million shots try to find a sanctuary or animal reserve where animals are use to coming into contact with humans. Often you will find in the right conditions, animals are quite the photogenic creatures.
Consider feeding times and heavy foot traffic. Fighting against the current can cause for missed opportunitiy. Instead set your shots up for a nice quiet day and take your time. If you reach out to the handlers they will ease the tension of figuring everything out. There will be many times where the shutter speed is going to need to be adjusted and you don’t wanted added frustration in your shots. hope this helps comment for any questions
