Oven Ready,
Your observastions of red jungle fowl are of great interest to me. Compared to my American Games, they are likely small and probably better fliers as well.
When you see them make the longer flights, can you determine if juveniles / subadults are mixed in? My American Games, especially the stags go through a stage where they can not fly as well as younger or older birds. Has something to do with molt where second chick feathering (flight feathers) is being replaced by first adult flight feathering. They also just starting to crow. Period of poor flight capability last 45 to 60 days. Molts later in life do not seem to limit flight as much.
Also, are flights motivated by need to reach another feeding location, avoidance of predators or avoidance of other groups of red jungle fowl?
