The song I heard I believe to be a Cerulean Warbler. I heard it again late morning in the Lower Campground of Garvin Park near the Host Cap site up high in the trees. Didn't see it, but have ruled out other helpful suggestions such as Towhee, goldfinch, and Redstart. The song is has a slight buzz to it, but is more clear than what I recalled Cerulean to be. Will try to monitor the site and get a visual confirmation. On this link: http://www.birdjam.com/birdsong.php?id=63 songs 9 through 11 on this recording match what I heard. Thanks to all who offered their input. Rog ---- Join or Leave mou-net: http://lists.umn.edu/cgi-bin/wa?SUBED1=mou-net Archives: http://lists.umn.edu/archives/mou-net.html
