Craig Tumer & I went to Kenilworth Aquatic Gardens in NE DC first thing this
(Sat, 5/31) morning, hoping to refind the Yellow-crowned Night-Herons that I
saw there last weekend.  Even though we were the first to walk around the
ponds, the only long-legged waders we saw were 2 GREAT BLUE HERONS.  A
passerine landed in the top of tree that turned out to be a female BOBOLINK.
Otherwise it was pretty uneventful, so we walked out the boardwalk.  A fair
amount of breeder activity, but nothing out of the ordinary.  While walking
back towards the ponds we ran into Barry Cooper, and then we walked out the
shorter boardwalk.  At the end of that walk we heard an ALDER FLYCATCHER
sing repeatedly.  We went back to fetch Barry, and returned to the spot
where we heard the flycatcher.  It took a little bit of waiting, but the
bird started singing again.  Then Sam Dotson joined us and we all got to see
the bird singing from the top of a tree in the marsh.

Just as we got back to the ponds, I looked to the right and caught a glimpse
of a LEAST BITTERN fly from the edge of a pond into the marsh.
Unfortunately I was the only one to see it.  Se we walked up to where it
flew in, and I did my best Least Bitter imitation.  Craig first heard
something moving in the bushes, and then the bird took off again, flying to
the left of us.  Craig walked up the side of the marsh and was able to
relocate the bird as it sat in a small tree.  We all got to see it well as
it just sat there, motionless.

From there we went to Kenilworth Park and then the Anacostia Wetlands.  But
both places were unremarkable.  There's still a fair amount of water at the
Anacostia Wetlands, so it's still possible for something interesting to show
up there.
