After briefly checking the impoundments I spent the rest of the
morning exploring the eastern upland forest looking for localized breeding
species.  Not a bad day-62 species.  Heard my first my first WILLOW
FLYCATCHER of the season calling from the buttonbush swamp and 2 singing
WARBLING VIREOS along the N-S dike.
Found the following territorial males of interest in the uplands-one PINE
WARBLER, 3 WORM-EATING WARBLERS, 2 OVENBIRDS, 1 LA WATERTHRUSH, and 1
KENTUCKY WARBLER.  The Pine Warbler was interesting because at one time
there were extensive stands of Virginia Pine in this area which have now
mostly disappeared as they are replaced by hardwoods.
       Found a White-breasted Nuthatch nest about 40' high in a Chestnut
Oak.  It was in a decaying area in one of the smaller trunks with the
opening facing downward.  Both adults were feeding, but I didn't hear any
young.
      Few migrants-11 Blue Jays, 2 Chestnut-sided Warblers, 1 Magnolia
Warbler, 4 Black-throated Blue Warblers, 7 Myrtle Warblers, 1 Rose-breasted
Grosbeak, and a late White-throated Sparrow.
