I checked on him earlier this morning when I walked Ozzy and he was still in the nest.
I did a little reading last night, apparently baby birds are called “nestlings” when they are first born and they have those floofy baby bird feathers. As those shed and actual flight feathers grow in, they are called “fledgelings”. At that stage they are close to flying.
When I found Randall he had some very nice flight feathers on his wings, but his back was naked. My guess is thst he is well on his way to flight status and just got a little overambitious.
