If an animal is dropped off to be helped and they accept it in, does the Wetlands and Wildlife Care Center have the right to euthanize the animal and cremate it without the person's consent who brought it in for care? Is this explained beforehand?

I would expect this is the case. The reason we bring these wild animals to this center is to rely on their expertise. As to the reality of such a policy I have no idea.

actually they do not ask you ! I brought a injured hummingbird there several years ago we found it pretty mangled we nursed it to like 80% but due to work schedule we brought it in ! they said they would fix it and release in our area ! we called to follow up the next day and found out they put it down this was heartbreaking since we litterally had it almost back to 100% they said it would not survive in the wild due to a broken wing ? crazy we were so upset they did this
