Well if this is really BL, he's been there over a month, and very possibly has been dead the entire time. There are other animals in the area that are known to scavenge -- vultures, bald eagles (yes! We have them here, they are awesome), bobcats, maybe panthers, feral hogs (which usually eat plants but it's not unheard of for them to also eat carrion). I won't be surprised if it turns out that these remains are pretty widely scattered after a month of decomp in hot, humid, swamp conditions, whoever they prove to belong to.
