I won't make a habit of reporting VA birds to MDOsprey, but these 
birds were seen within sight of Maryland and DC, so I thought they 
might be of interest:

On Sunday, Jan. 7, a.m., I saw an immature Nashville warbler on the 
west (non-Potomac) side of the Hunting Creek bridge (just above Belle 
Haven picnic area). The bird was seen in dense tangles just beyond 
where there is a wooden stake with a pink ribbon, just a few yards 
south of the bridge over Hunting Creek. It was in company of a 
ruby-crowned kinglet and some white-throated and song sparrows and 
kept mid-level in vine-covered young trees. It was a colorful 
individual, with mostly (save for a bit of whitish just before the 
vent) yellow underparts and greenish-yellow back. Head was light gray 
with a weak whitish eyering. Gray extended around hindneck and down 
to beginning of back. Bill was thin, tail shortish. It was active and 
called once (a thin, weak one-note call). Well seen for about five minutes.

On the opposite side of the George Washington Parkway, in the 
Potomac, a cackling goose was scoped close to the shore among the 
several hundred Canada geese present.

A peregrine falcon flew overhead at one point, headed north.
