Don't know about everybody else but I get no audio with your youtube, and the title is IMG. Just upload your VDO directly to your question. :-)

This bird always wakes me up at 04:00 with his absolutely abrasive noise. Here is my recording: https://www.youtube.com/watch?v=4TsKFUugot8&feature=youtu.be#t=06s

Please help, I really need to know what bird this is.
