I went to Rock Creek Park this (Sun, 7/1) morning in hopes of relocating the
Louisiana Waterthrush and Black-throated Blue Warbler that I saw there 2
weeks ago.  I was able to refind the waterthrush, but not the warbler.  The
waterthrush was not singing this time, but heard calling.  Also saw several
very recently fledged Wood Thrushes, and heard an Ovenbird.  

Good birding,
