Nesting waterfowl are known to take several ‘recesses' or breaks from
incubating their eggs each day. During these recesses they replenish
their own energy supply at a nearby wetland. This mallard hen is
preparing to leave her nest for a mid-morning recess. She is covering
her eggs up with grass to help disguise them from passing predators and
aid them in thermoregulation during her absence.

nests at a Ducks Unlimited property in central North Dakota. DU is
collaborating with UND on the nest cams project to study the habits of
blue-winged teal. To view the full videos, go to UND's Wildlife@Home website and see how you can participate in this citizen science project. Discover other DU research projects at www.ducks.org/pprresearch.
