If you’ve not come across Cornell yet, their website and service is amazing. It comes in two flavours. I began by using their bird identifiaction app which is called Merlin. It is totally free an allows you to upload a photo of that LBJ and together with some additional information (date, location etc) you stand a good chance of having the bird’s identification served up top you.
The second service enables you to find birding hotspots locally and to create a bird list. You can see mine here.
