Sounds and video

I am trying to find observations that have sound or video as key elements for the identification. Starting off with a bunch of soundcloud sounds, will also search for youtube. Any other suggestions as to media that might have been used for ispot observation identifications (other than photos and descriptions)?

youtube videos

vimeo ones here:

It is always useful to have a still from the video or screen grab of the sonogram to have as the main photo in the observation. This is a comment to me as much as anyone as quite a few of these are my observations!
