I had dinner before coming to the park, so I missed his fly out from a new roost tree. But I did get to see him get his dinner. On some nights he’s been eating small rodents, most likely White-footed Mice or juvenile Brown Rats which he eats whole. Tonight it was a mature Brown Rat. These take some time to eat.
He hunted from his favorite branch, and picked at the rat on the ground before flying off to a nearby tree. He was hot after flying, paused to cool down and then ate the rat. Once he got it to a smaller size, he ate what was left in a single gulp.
After finishing, he went to a tree over looking a path, and then flew east. We couldn’t find him again.
