Alice, that is indeed a good rehabber listing site, but may be a little out of date since the webmaster has not updated that site in a couple of years, but it is a great start. A much smaller, but more up-to date listing is at http://wildliferehabber.com/modules/xoopsmembers/
Also, most states also have a Department of Natural Resources (DNR), or something similar (in Virginia it is called the "Department of Game and Inland Fisheries") where under the topic of "wildlife" there often is a listing of wildlife rehabbers licensed in that state.
The National Wildlife Rehabilitators Association (NWRA) web page also has links to helpful sites to locate rehabbers nationally:
Unfortunately, there is NO single comprehensive listing of all rehabbers in the country. So it may take a little searching and phone calling to get to the right person in your region.
