Hi Erin,
Return-to-field, also called shelter-neuter-return, is a variation of TNR. With TNR you identify a cat or a colony, then go trap, vet and return. Return-to-field is where a cat comes in to an animal shelter or animal control agency because a member of the public brought the cat in or an animal control officer trapped the cat as a result of a call/complaint, then the cat is admitted to the shelter, then, if deemed eligible, vetted and returned back to where the cat was found. A lot of the mechanics are the same. The differences can be a bit "inside baseball" but the stuff Bryan, Suzi, Karen and I like to talk about.
There is a lot of good information in the handbook, which is free to download, including information on RTF collaborations between municipal shelters and TNR groups. We aimed to provide helpful information for a wide range of folks.
