luv2bird:I use the observation data on their site all the time, but ornithologists grimace because the sightings are not confirmed.
that is partially right.. common , or expected birds are not confirmed, but rare, or unusual sightings are confirmed by requests from them for photos. I have had several reported, and confirmed. Ebird is a great site to use if you are going into an area new to you, as many sightings are mapped and recorded. However, the data base is still small, so not all sightings are reported to them.They could use input from us Whatbirder's for sure. It offers lots of way to track, and keep track of birds in certain areas, by region, state, or country. I love it.
