Rulings:

• 8/7/2020 If you don’t control a black permanent immediately after Parasitic Strix enters the battlefield, its ability doesn’t trigger. If you don’t control one as the ability resolves, no player loses or gains life. It doesn’t have to be the same black permanent both times, however.
• 8/7/2020 Parasitic Strix’s ability triggers only once, no matter how many black permanents you control beyond the first.
