"Fieldnotes," September 8th & 9th, 2013: "Mallard Sleep," written by Kassy Holzheimer, read by Nicole Schegg.

"Although technically, the mallard is sleeping, one side of its brain remains active throughout the night. The open eye usually points towards potentially dangerous directions, and when it recognizes a danger, the mallard becomes fully awake quickly and can usually escape."
