Many successful wildlife photographers have said similar things in the past, and it is only really the location that varies. Wildlife photography reminds me of an old paradox from my religious instruction classes in school:
"Praying while you are working is OK, but working while you are praying is forbidden."
This paradox perfectly embodies the dilemma faced by every wildlife photographer: You can't observe wildlife carefully and photograph the animals you observe successfully, but you can combine successful wildlife photography with the scientific observation of animals. Focused, precise observation is, in fact, an absolute must if you want to photograph wild animals.
