To Tweeters:
I forgot to mention on my posting earlier today that I camped out at the
Packwood Ovenbird site last night to see if it performed the very different
nocturnal flight song, which it does at treetop level (much like European
Woodcock's "roading" display). Unfortunately, I only got in a few hours of
night listening. I have heard Ovenbirds do this song at midnight in the
southern Appalachians, but I was not awake at that hour.

At the URL below you can hear a sample of the paired phrases that the
Packwood bird was doing. The text is from my upcoming CD-ROM of birds of
Puerto Rico, so it refers to winter ground conditions. Click on the link
in the "voice" section. The audio is a large file at 360K, and even at
that, it is truncated, and 8 bit. The normal interval between songbursts
in the Packwood bird was 15 seconds. I cut out some of that intervening
silence to save on download time:
