Want to put a sighting on eBird but don't want to share it with the rest of the world?
Rather than entering false data (inaccurate location, numbers, whatever) then putting hints about the REAL data in your comments, just use the "HIDE" tool!
Just click the box beside "Hide from eBird Output" found at the bottom of the list of tools on the right-hand side of your screen when you are viewing a checklist.
Command path: My eBird < Manage My Observations < View or edit (the checklist in question) < Hide from eBird Output
The sighting data will show up on your personal lists but NOT show up on maps and bar charts. You may change this box at anytime (check / uncheck it).
It is NOT recommended by eBird, of course, but several reasons may occur to you, which I will leave to your imagination, but at least you will have your own lists and data available to you.
