An oxymoron.
It is speaking about the state of bird photographers who will do anything to take a great photo of wildlife. The list of actions include:
1. Feeding of wild birds
2. Stepping on wild birds 'by accident' (OBVIOUSLY they just dont want others to get the same photo opportunity)
3. Recommend culling of bird's native predators
4. Pushing their way around with their massive lens to get a good position and refuse to move even if obstructing the path
5. Witholding information of bird locality, even if information would be vital for ornithologist conducting avian research
6. Breaking local rules and entering restricted areas, endangering lives of those around them
7. Handling of wild animals to prevent them from disturbing their subject
8. Unnecessary destruction of vegetation in wild areas to get clearer view of the bird
Find me an ethical birder in this day and age and I will bow to them.
