At 8:30 am the ducks were already active. I counted 25 though not all of them appear in the video. We hope this floating vegetation will not be removed since it is the only area which provides some protection. At the back two Rufous-sided Crakes appear at the end of the video.
A synchronized duet between a masked gnatcatcher, which appears on the video, and a tyrannulet which was across the road. The tyrannulet begins and the gnatcatcher closes
