Dear .,
This is a Louse Fly in the family Hippoboscidae.  Adults feed on blood.  According to BugGuide:  “Most are host specific on bird species, with a few occurring on mammals.”  One species feeds on the blood of sheep and is known as the Sheep Ked.  Perhaps you live near an area where sheep are raised, but since we don’t know where you are located, we cannot say for certain.  If their preferred host is not available, opportunistic Louse Flies may bite humans.

Your concern was appreciated, keep it going!
As for my location, my locality homes quite many pigeons and cats, if that’s what these Louse Flies are feeding on.
