Sibe Chiff Plymouth

Just to give an idea of how messed up this bird is on vocalisations, Laurie Allnatt has uploaded some videos to YouTube that he made this morning where you can hear it calling something like tristis and mixed singing.

In the crudest of ways (put microphone of headset next to earpiece to record!), I was able to extract some sound and generate a very low quality sonogram from the third video. The inverted U shaped call starting at about 4.5 kHz looks pretty good although it sounds a bit happy for a tristis to my ears.
