Ikiti Tikilikrr had been outside, stretching her wings and eating lunch with her roostmate. He wasn't her preferred mate, but that wasn't really an issue outside of the breeding season, and for that she would get to go home in any case. The Liftgivers were not yet willing to risk the health of outsiders with the Tikrr's tendencies for aggressive behaviour during that part of the reproductive cycle.
However, part of her lunch wasn't cooperating. She and her roostmate had hunted a preinjured kistyr as the main course, but Ikiti's most favourite farmed food were tirisherr, so she had spared one for dessert. Unfortunately the annoying four-winged fuzzball didn't react like the ones before it had. Instead of heading out to the open sky, as soon as Ikiti took after it, the terrified critter darted down, towards an opening in the building's side, one of the fragile doors that were called "windows".
Ikiti drove herself into a steep dive to catch the tirisherr before it reached the window, her larger mass and wings giving her greater speed. The white fuzzball realized this as well and, using its one advantage over Ikiti, its agility, shot away from the vertical wall. But not quite in time; Ikiti had already started her strike, which meant inverting her position from head-first to feet first.
The claws on her hind limbs were her main lethal weapon as a predator. She tended to only use her jaws for the killing bite on smaller prey, if they didn't die fast enough after being impaled by up to ten curved blades, each about 10 cm long. On larger prey she would hold on with her jaws and slice into it with her claws. The kistyr, which Ikiti and her roostmate had devoured earlier, was right between those two sizes of prey for a single Tikrr to tackle, but for a pair it was easier with Ikiti as the larger one to hold onto it, while the male made a quick kill of the helpless animal.
The tirisherr's attempt at freedom was cut short by one of Ikiti's hind claws, which razed across its back, catching onto one of its hindwings, but it was still a miss on Ikiti's side as well, since although she managed to stop the creature, it slipped off her claw, more falling than diving, but with just enough control that it managed to aim for the open window.
Ikiti had no choice but to go after it.
