First walk and stalk Warthog

[Henry84]

Good day to all,

In June I went on my first hunting trip. We hunted from blinds and I managed to shoot a warthog.

I have the opportunity to walk and stalk warthog, I need some advice.

When do they prefer to drink? On the farm we hunted they drank morning noon and evening but is this the norm?

Do they prefer waterholes or streams? As the farm I am visiting has both, but the previous farm only had watering holes.

Any advice will be appreciated.

Regards,

Henry
