Several large colonies are located in south Puget Sound. Great Blue Herons nest in large groups in tall trees near the water. The Great Blue Heron feeds mainly during the day, but occasionally will hunt at night.
They even eat mice and other small mammals while patrolling open fields. When fishing in freshwater, herons eat frogs, fish and crayfish. To avoid getting spines or fins stuck in its throat, the heron shifts the unlucky dinner to a head-first position and then swallows. When prey is spotted, the neck unfurls hurling the head forward with lightening speed grabbing the unlucky meal. Hatching occurs after 23-25 days with the young immediately leaving the nest. They often nest far from water, where they build a concealed nest of dry grass and plant stems. Like other dabbling ducks they tend to nest earlier in the season, risking impacts from late winter storms. They leave in early spring for their inland, freshwater breeding sites.
including as far north as northern Alaska and both the western and eastern parts of Canada. and Mexico including the Caribbean Islands. The American Wigeon ranges throughout North America with winter sojourns to the southern U.S. In addition they also come up on lawns to eat the grass. The other interesting aspect of their behavior is that they feed heavily on marine vegetation, mainly Sea Lettuce, during their winter layover. The call is very unusual and fun to listen to. While feeding along the shoreline they communicate with other flock members using a high whistling call. Hybridization between the species regularly occurs. The Eurasian Wigeon male has a dark rufus head with a muted white crown. However both males and females will occasionally stray south to Puget Sound. A close cousin, the Eurasian Wigeon, normally winters in the Aleutian Islands and Bering Sea.
