I was hoping to see or hear a Yellow-throated Warbler today.  That 
didn't happen, but I was moderately surprised to hear the Louisiana 
Waterthrush singing at the usual place along Kingsley Trail.  I've never 
before seen or heard him before April.


Later in the AM, I tried Owl Ridge Trail (n. LB), which I had not done 
for over 10 years, because I never seemed to see many birds there.  That 
was true today also, but there was one bird that puzzled me.  High in 
the first (northernmost) pine grove, I saw a bird with bright yellow 
throat, breast, and belly, a white vent, and gray wings.  There was no 
obvious streaking, etc. (but I probably can't rule out faint streaking, 
as on a first winter Magnolia Warbler).  I was almost directly under the 
bird, so I couldn't see much else, but it turned its head slightly to 
the side momentarily, and I think I saw both yellow and black on its 
face (but couldn't see a pattern).  Blue-wing Warbler seems like the 
closest match, but I wouldn't expect that to be high in deep woods.  The 
habitat is also wrong for the first winter Magnolia.  Pine Warbler 
matches the habitat best, but I think there was too much yellow on the 
bird I saw, and the yellow was too bright.  Unfortunately, the bird was 
not vocalizing.  Any other suggestions?
