There is this secluded corner of the building at work where the Vultures return year after year to lay their eggs.  I believe these to be Black Vultures.  There are two baby birds this year, and typically they will stick around for about three months or so.  This spot is next to a conference room, so you can take pictures through the dusty windows without disturbing the family.  It is a unique experience to watch them grow up, learn to fly, and then leave this temporary home for another one.
