Great Blue Heron Early Spring Rookery

Even before the snow has left us completely, the Great Blue Herons arrive in the rookeries. The first males to arrive get the prime, strongest nest sites within the rookery. These same nests may be used year after year, or new ones built. They defend their territory from other males, eagerly awaiting the arrival of the females. Females are greeted with elaborate displays and calls from the males. (You can hear the soft “Whoo hoo hoo” call on the first clip in the video) The males often present branches to the female to start the nesting process. Once paired a clutch of 2 to 6 eggs will be laid and 1 or 2 broods will be raised each spring by the duo.
