How To Draw A Northern Shoveler Male
Habitat
Northern Shovelers use shallow wetlands with submerged vegetation during the convenance season, nesting forth the margins and in the neighboring grassy fields. Outside of the breeding season they forage in saltmarshes, estuaries, lakes, flooded fields, wetlands, agricultural ponds, and wastewater ponds.
Back to pinnacleFood
Shovelers eat tiny crustaceans, other aquatic invertebrates, and seeds which they filter out of the water with comblike projections (called lamellae) forth the edge of the beak.

Nest Placement
Females make a modest depression on the ground, more often than not in areas with brusque vegetation within 150 anxiety of water.
Nest Description
Females use their torso, feet, and neb to make a small low on the ground nigh 8 inches broad. The nest scrape is unremarkably surrounded on at least three sides by vegetation and lined with downy feathers.

Behavior
Northern Shovelers swim through wetlands, often with their bills down in the water, swinging them side to side to filter out tiny crustacean casualty. Sometimes large groups swim in circles to stir upwards food. They don't provender on state regularly, but they do rest on country and walk along wetland edges. They are fairly social ducks, occurring in groups with shovelers and other dabbling ducks, especially during the winter. During the convenance season, they are less tolerant of other shovelers encroaching on their territory. Defensive males often chase intruders on the water and in the air. Males courtroom females on the wintering grounds with turns, dips, wing flaps, and caput pumping. Pairs stay together during the convenance flavor, although males volition occasionally mate with a 2d female. After breeding, males group together in pocket-sized flocks earlier and after molting. Males molt their flight feathers earlier migrating s, becoming flightless for a cursory period, when they tend to stay hidden in vegetation peculiarly at night.
Back to summitConservation
Northern Shovelers are mutual and their populations were stable between 1966 and 2015, according to the North American Breeding Bird Survey. Partners in Flight estimates the global breeding population at 4.5 meg. The species rates an 8 out of 20 on the Continental Concern Score, which means information technology is not on the Partners in Flight Watch List and is a species of low conservation concern. The U.S. Fish and Wild animals Service advisedly manages duck hunting, and limits the number of individuals hunters can accept every year based on population size. From 2012–2016, hunters have taken an boilerplate of 705,533 Northern Shovelers per year.
