The advice to never pursue wildlife is good.
However, once in a great while, I’ve had wild animals that came right up to me and seemed comfortable just being around, even looking curiously right into my eyes. This did not involve any feeding or other human tricks. I merely had been sitting still for a long time.
The standout marine mammal encounter happened on a self-supported kayak trip in the Inside Passage. The four of us paddlers noticed a humpback whale was swimming parallel and close to us, and it had been doing so for a while. Matching our pace. We could hear it regularly making some kind of sound underwater, too.
Unfortunately, a boat maybe half a mile away suddenly turned towards us, obviously speeding up “to see the whale, folks!” Our big buddy dove deep and disappeared for many minutes, during which time the jerk boater got next to us and circled around, obviously hoping we would “point where he went!” NOPE. We kept our lips sealed and arms signal-free. Azzholes had scared off the whale, dumbfcks. We were angry.
Sad to lose our pod companion, we continued, silent. After many minutes had passed and the jerk boater had sped out of sight, guess what happened. Our buddy quietly reappeared next to us, in exactly the same position relative to us. We must have paddled 4 or 5 miles with him in all. An encounter I’ll always cherish.
