Most of the birds I saw this AM were the summer residents.  However, I heard 
an Olive-sided Flycatcher twice, then a few minutes later I got a glimpse of 
a bird (before it flew away) that was consistent with that ID.  It was west 
of MD121 near the foot bridge over the creek.

Although the Kentucky Warbler at Earl's Picnic-Ground was singing 
constantly, I never got a look at him.  He seems to be patrolling a 
territory.
