Just to throw in a different angle, if you do spot a bird that's out of range or simply unusual, isn't a good idea for that info to be included in a data set so it's area and numbers are better understood for conversation? Perhaps a selective sharing of the sighting is actually helpful in some cases. I feel as photographers and nature lovers we owe it to professional conservationists to help build up informed data.
As mentioned previously - the eBird system provides a world-wide public database of bird sighting data including locations. It has both desktop and mobile apps for entering bird sighting information as well as viewing the data. It's a project managed by the Cornell Lab of Ornithology.
