Thanks for posting this question, as I think it brings up some very interesting points and should offer us some pause for thought.
As to the answer to your basic question, I do not share locations on the web, to those who ask via email, IG, Facebook, etc... Furthermore, with the exception of two photographer/environmentalists like myself, I do not share my locations.
Reason:
First, let's acknowledge that in the US there are many known locations to photograph wildlife in captivating locations. These include places like Florida wetlands, East Coast wetlands, National Parks, and state parks. One simply needs to look on the NP, SP, or known city tourism sites, find if their is a loop road, boardwalk, or "birding tips" to know where to go. This data is freely available to the public and one expects to find photographers in these locations... like the Hayden Valley in Yellowstone, Sage Meadows in the Tetons, or Corkscrew Swamp in Florida... to name a few.
Why I don't share...
Twenty-five years ago wildlife photography was relegated to the more hardcore photographer. Sure, people brought their cameras on vacation to National Parks and purchased lenses that were used once or twice a year, but these cameras produced prints or slides from film, were generally good enough for the photo album, but were relatively poor in composition, exposure, and timing. Film was expensive and photography required knowledge about exposure, appropriate shutter speed, and best apertures for a given image. I used to travel with 50 to 100 rolls of Velvia & Ektachrome and hope for 20 good shots. I made money, and nobody went to the places I went. In fact I spent 8 days backpacking in Denali to get a few good bear landscapes hiking through an autumnal tundra-covered hill... Back then I could tell someone where I saw a great grey owl, and nobody would care.
Enter the present... Relatively little knowledge is required to make a decent photo. People have become actors in their own reality shows and want to be famous (whatever that means). Instagram and Facebook feed the dopamine addiction with their little hearts, and people now have instant access to every possible location. As a result, if only 3 percent of the so-called - wildlife photographers disrespect a location, the place becomes spoiled, the wildlife becomes wary, and often suffers from the human intrusions.
Case in point... in 1993 I went to the Sax-Zim Bog 3 or 4 times to photograph hawk and great gray owls. These trips were either day long or multi-day trips. The location was disclosed to me by an owl researcher who wanted photos to share with her class. I was an ecologist/photographer/biology teacher. In the time I was there, I saw only myself and shooting partner as well as one resident who lived at the edge of the bog. Today, if one goes to the bog in winter, you will encounter birding tour busses and at least 50 other vehicles driving back and forth on the same road and visiting the same feeders. The location is spoiled for photographer and for the wildlife... the charm is gone. I can recount endless stories like this.
Moral... if you've got a special spot, keep it to yourself as you will be doing your wildlife subjects a huge favor.
