not sure how long, but i had feeling that the little guy will run out of energy rather quickly without constant feeding, and sure enough within 5 min, it was dropping and landing. got caught in the spider web and that gave me chance to put it in one of my old hat and take it outside.
had some problem flying, try to find the nearest flower patch, but.. well all my flowers are inside of my figs. he dropped on the grass and i had chance to take spider web off its beak. as soon as i finish cleaning the web, it flew off. hope he finds some flowers quick. he looked really tired.
