The most common eastern early spring trill would be the Dark-eyed
Junco.  Let me know if you need an example.

Subject: Presenting sounds on the internet


About ten days ago there was a discussion on this list server
about presenting bird songs on the web using HTML and mp3 files
as compared to using Quicktime.  I want to mention another
option, using Flash.  Before getting into that, let me start with
an introduction, since this is my first posting.

I am Rick Johnson of Inverness, California.  I started recording
by attending the Cornell Lab sound recording workshop in the
Sierras in 2001.  Thanks to Greg Budney, Randy Little, and David
Herr for getting me started on what has turned out to be a
fantastic journey.  Once I started paying attention, I noticed so
many more sounds, both pleasant natural sounds and irritating man
made sounds.  I also like to do video recording although in any
given scene I usually concentrate on one or the other.  I use a
Sennheiser ME 67 mic and Marantz PMD222 recorder, and have been
satisfied with the set up. Most of my work experience has been in
product development for application software companies.

Eighteen months ago I decided to build an on-line Introduction to
Bird Songs.  I considered using HTML and MP3, Quicktime, or Java.
None of them really gave me what I wanted in terms of designing a
responsive, graphical user experience.  I decided to use
Macromedia's Flash.  Flash allows you to mix in images,
animations, along with sounds.  Flash does a great job at
compression and at providing portability to most browsers and
platforms (PC and MAC).

You can check out the results at my web site, www.hearbirds.com.
On the home page there is a simple example to play a Hermit
Thrush song.  In the lower right section of the home page there
is a link to test your Flash version and that leads to a site
where you can get the needed free plug-in, if necessary.  There
are more complex examples too.

This next link goes to an article that talks about spectrograms
and illustrates one for a Green-tailed Towhee recording:
http://www.hearbirds.com/content/sono1.htm

This next page has a demo of the types of recordings used in the
course:

HTML and MP3 seems to be the best way to build a catalog of
sounds and to share them.  But if you want to build something
more graphical and mix in other media, Flash does a great job.
