They can forage to well over a mile (well 3 actually)
This is peak for them, lots of larvae to feed and lots of energy to flap those wings to get air flowing through the nest and maintain the proper temperature. You said 04AM before work… If your house if the only with light at that time regularly they sure have found it to be a good hunting ground during this time.
Next time do not wear heavy smelling deodorant and do nit strike at one just let it be, they are so big they feel and act like king of the hill, not easily threatened or aggressive.
Smile knowing less pesky insects are there to ruin your night shots 
Found the nest? Just leave it and shine the other way and they are kind of allies!
