This a.m., I was surprised to find a singing prothonotary warbler off 
Jones Mill Road. I first saw it from the purple-blazed path that runs 
from behind purple playground equipment just off the road, near the 
Woodend entrance (but on the other side of the road). About 100 yards 
down this path there are two fallen trees side by side and a good 
view of Rock Creek. First heard and saw the bird there.

About 45 minutes later, the bird was singing at the edge of a small 
swamp that sits right off the paved bike path and very close to the 
small tract owned by ANS (which is adjacent to Rock Creek Park and 
across the street from Woodend's main entrance).

I saw that a photo of a prothonotary was posted on the signboard 
where the ANS property meets RCP. Does anyone know if the birds breed 
here? I don't think I've ever chanced upon a prothonotary anywhere in 
Rock Creek Park in Montgomery County. Then again, I've never really 
birded this path before....
