Hi everyone-
I’m a lurker on this list as I don’t do a whole lot of night flight call 
listening and recording.  However, I’m working on a painting of a 
black-throated blue warbler at dusk during the autumn night migration, as part 
of a group art show next year.  I have a couple of questions for you all.

  In addition to the actual painting, I’m going to frame a screenshot I grabbed 
of migration showing up on the northeastern US Doppler radars from the National 
Weather Service (public domain, fortunately), to help people visualize the 
scale of night migration.  I was thinking it might be fun to also include a 
spectrogram of a BTBW night flight song if anyone has one available and 
wouldn’t mind having me put it in a show, with appropriate credit, of course.  
Is anyone is interested in sharing a spectrogram?

Our group art shows, which all have a natural science theme, usually go to at 
least 3-4 venues in upstate NY, so it is a good way to educate people.  Here’s 
a link to our past exhibits (website needs a bit of updating!) if you are 
interested in what we 

One other question - would it be likely that the BTBW would be joining a large 
flock?  I keep wondering if I should put little bird specks into the more 
distant sky.
