Ryan,

my first thought was that it did not sound quite right as compared to 
the Willows that I hear on our BBS routes in the area. However it is 
much more like the Willow than the Alder when I compare the two calls on 
the Cornell site.

In fact as I played the Cornell Willow and your bird together, your bird 
clearly, in my opinion, is a Willow.

Do you know if one can park at the golf complex off ov University Blvd? 
That site is just up the road a little from my house in West 
Hyattsville. I have often wondered if the trail was open to the public 
in the4 area of the golf course, but have never investigated.

The map is a really helpful guide. I hadn't realized how they could be 
annotated.

I'll have to try the area this week.

Best wishes,

Tony Futcher
West Hyattsville, MD

I got clean looks for a minute (but didn't know which subtle cues I should've been looking for), but was fortunate that it was singing still.  It only sang for about 2 of the 10 or so minutes I was there.  Here's a recording (that's a plane overhead for the first half of the recording, the last 15 seconds or so are very clear of the bird's song/call).
