Sorry to drone on... but this may be unique?

With all relevant permissions and legalities, myself and a professional drone pilot, got this video and several still shots of a Heronry without upsetting the birds. This female simply stood up to show the eggs as a Swan does; to tell you what she is doing as apposed to fleeing in terror or attacking, if she perceives you as a threat. We backed off immediately anyway, just in case and with all due respect.
