Concession: Fine, I'll feed you... (Falco peregrinus)

This chick seemed both hungry, reluctant to fly, and impatient. It seems the mother wanted him to try hunting by himself, but he insisted. He flew at her a couple of times, hovering right over her and screaming so loud it seemed exceptionally loud from about 20-30 meters away.
Finally, she relented, let him land next to her, and began feeding him. He calmed down after that.
