Perhaps it would have been better to send you a PM, but then I thought as it was dealt with on a public forum, I should rather respond here.
I reckon that you are maybe a bit harsh with your condemnation on our "party" regarding the incident with the crow in Kgalagadi. I know as well as you do, and I share your hefty disapproval of it, that feeding and disturbance of any animals in a National Park or other nature reserve, are to be adressed in a serious manner.
And I am not trying to find excuses for our "party's misbehaviour regarding the mentioned incident - a wrong is a wrong and cannot be varnished over. But to a certain extend you are judging our "party's" disorderly conduct out of context.
Just as a matter of background - I am a serious nature lover as you are too (being a professional wild life photographer). I spend about all my holidays in National Parks and gets very upset when people do things (like feeding animals, speeding, etc) that should not be done in a park. Since 1986 (when I started recording my visits) I have spend 85 nights in Kruger, 36 nights in Kgalagadi, countless days in Karoo (where I will spend another 9 nights from this coming Friday) and visited many of the other parks like Bontebok, Addo, Tsitsikamma, Vaalbos, Golden Gate, Mountain Zebra, Augrabies, etc. And I can assure you it was not to have zoo- or circus-like experiences. As a matter of fact, I am presently in correspondence with two different regional chairmen of the Honorary Rangers to join their ranks.
What happened with the crow incident was rather a unique episode. Normally our "party" would give no consideration to feed any animal. As the crow's behaviour was very strange, by flying next to our vehicle (on window height) and making their typical loud noise the whole time, as if to attract our attention - we were amazed by this strange conduct by a wild bird in such a remote area. We said to each other that it is doubtful that a wild bird (far away from any human settlement) will be begging for food from a travelling vehicle. Knowing that crows are kept as pets on some farms (against the law, naturally), we wondered whether it can be a bird which "escaped" from detention. It was then that my son-in-law said that if it is a wild bird it will surely not take anything from somebody's hand - not to speak of taking something from a person's hand coming from a moving vehicle. And that is how (and why) the incident took place. I am up till this day quite convinced that it was a tame bird that ended up (somehow) in this very remote area.
I plead culpable on behalf of our "party" for rendering ourselves guilty by trespassing a rule/regulation/law - but it was done (wrongfully) to confirm our presumption.
I really hope you can somehow find a bit of extenuating circumstances in your conclusion of our "party's" action. I apologize (and I really mean it) to you and all other lovers of our beautiful National Parks if what we did was a short-sighted deed.
