I swam out to my little island yesterday and it was full of birds, and eggs. The birds almost formed a cloud of birds.
It was very cool.. When I get to my desktop computer at work, I’ll try to upload a video, so you can hear the sound.
And here it is. Sorry about the wind noise. But you can also see several “nests” which are really just eggs laid out in the open.
LINK to video: If you right click, you can save it as a MP4, if it doesn’t load fast enough to watch.
