Is there a web site where I can hear bird calls to help identify the bird ?
Yes...here's an excellent site: http://www.allaboutbirds.org/guide/search
not that I know of. google it
Given the ubiquitousness of the world wide web and its size, I would be genuinely shocked if one didn't exist. Somebody more skilled at computer usage than myself will probably answer this and provide a link. Stay tuned.
Try the Cornell Ornithology Laboratory.
