Here are some scenes from the night homing ability competition. Birds from the lofts in Downtown Denizli are released around 11PM at Pamukkale (25km distance).
Hey Steve, They return but I don't think they are timed. They are expected to return by the day break. The ones don't make it by then are not kept in the loft any more. Breeders pay close attention to the homing ability and value it almost as much as the performance.
