The trick with wildlife is more about getting close (safely) and observing, with a little luck, rather than technical or equipment concerns. Get your settings right before the animal does something interesting, fire off some test shots.
Time of day is a tricky one, often the rule is early or late to get nice golden hour light but wildlife doesn't always follow the same camera tip blogs as we do
You need to know what time they tend to appear. Knowing their behaviour or pure luck gets the best shots.
My preference is for the animal to be big in the picture while keeping some habitat context. Getting some interaction between mothers and young is always guaranteed to melt hearts. Main thing is to be quiet and patient. Find a good comfortable spot, use a tripod if you have one and can be in a busy spot. Fire off loads of shots and keep shooting. You can edit out the rubbish later.
Best tip of all, ask people who have grabbed great shots in the area some tips, especially where to stand and what time of day.
