I’m amazed at the scope and power of Cornell University’s eBird, an app and a huge global database and much, much more. I’m starting to plan a road trip up north to find the Sarus Crane. Well, with eBird I can look up dated sightings at hundreds of locations, telling me where I’m most likely to get good results. Interestingly, some bird species are classified as sensitive, their locations not to be revealed. These are birds that the world needs to keep private because of very low numbers, or systematic hunting, or rapacious land developers, etc. Of my fifteen Crane species, only three are shielded by eBird: the Whooping Crane (but only in Wisconsin), the Common Crane (but only in the United Kingdom), and the Sarus Crane (but not our Australian race, instead one in an Indian location).
