Unidentified bee(or wasp?)

Observation - Unidentified bee(or wasp?) - Global. Description: There is a nest of whatever this species is in a vent along the edge of our building. Hundreds move in and out most of the day and, as I managed to photograph this one unfortunately deceased, I was curious as to what they might be?
