I scout out and think through every release prior to making it. I want to leave the wildlife in a place that fits its physical situation. When I do the actual release, I try to release it near where it was found. That gives it a chance to be back with a mate. Sometimes that is not possible. Then I decree a divorce and release it in a location where I think it can thrive.
Most birds can be released any time of the day because they are day fliers. Owls are a different matter. Since they are night fliers, they must be released at dusk. I do that a half hour before dark because then the crows have gone down for the night. I want to keep the crows from attacking an owl that is adjusting to its surroundings.
My goal for all wildlife I rehab is have them back in the wild where they want to be. I take special care to make certain they have the best location to do that.
Thanks for caring about the critters,
