I've just returned from Susquehanna State Park and heard and had good views 
of  an ALDER FLYCATCHER!  The bird was actively calling from an open area 
not far from the trailhead from the picnic area.  To access the area, you can 
take the trail into the woods.  Cross the small footbridge.  You will then come 
to a point that forks 3 ways.  (There is a sign that says "Forest Buffer 
Demonstration Area"  Take the middle fork.  Not far from this point, the woods 
start to open up to a low shrubby area.  The bird was calling and actively 
flying in the shrubs in the open field area to the right.  You can also access 
this trail from a different route.  Coming from the Rock Run area, heading 
towards the Picnic Area parking lot, there is a brown barricade on the left 
hand side (before you come to the Picnic Area)  Walk this unmarked trail, 
behind the barricade, which is open at first, but quickly becomes wooded.  
When it becomes open again, you will see the low shrubby area to your left 
this time.  Hope this helps.  Warblers included a CANADA and MAGNOLIA and 
BLACKPOLL WARBLERS were just about everywhere!  CEDAR WAXWINGS 
seemed to be everywhere as well and I had good looks at a VEERY and a 
SWAINSON's THRUSH.
