Wednesday a caller indicated they’d heard the grounded nestling calling the previous day but thought the parents would either feed the baby where it was or coax it into a tree. This had not happened by Wednesday morning so they retrieved the baby, who was screaming for food by this point. They couldn’t transport it for several hours so I started calling volunteer transporters. Mammal rehabber Charydi Gambill had him to me within an hour or so, whereupon he was promptly fed as much as his little belly would hold (unlike other birds, owls do have bellies rather than crops).
