While most of the websites unfortunately are mediocre, some include bird checklists, detailed itineraries, photo galleries, maps, and other useful information. Even the basic sites can enable you to identify accommodations mentioned in trip reports. I have in most cases deep linked to bypass the all too prevalent and counterproductive graphical splash screens on lodge index pages. If a site on a third-party domain has gone dead, try the name of the company or lodge as the domain name. When pages have gone down, you can sometimes retrieve a cached copy out of Google .
Most links are to first-party websites, where they are known to exist.
If a third-party site offers significant useful information not found on the company's own site, I have linked to the alternative site or to both sites. A lodge's environmental practices are irrelevant to listing here. Twitchers are unlikely to be interested in an accommodation simply because it recycles the garbage. Indeed, places with environmentally questionable practices sometimes offer better birding opportunities.
