My interests in image recording sent me to this Nikon website - I was looking for some high powered lens for wildlife recording, with sterio audio and GPS.   What I surprizingly found is this Nikon advice on birding etiquette.   Read it - it isn't pablum but the real deal...

I compliment Nikon for being a corporation which on this web page hasn't spun...greenwashing.

Here is a link to the Nikon bird watching etiquette web page.
