Heron Watch - Free Program
Observe the Magnificent Great Blue Herons and Their Chicks at Stow Lake
Six Saturdays During the Spring Nesting Season in April and May
2015 season starts April 11 and concludes May 16, 2015.
Nancy DeStefanis, Executive Director of San Francisco Nature Education,
was interviewed by Bay Nature Magazine about the Great Blue Herons
at Stow Lake and the Heron Watch Saturday program (Bay Nature Magazine Online- April 15, 2013).
Back again: Great Blue Herons Nest at Stow Lake
In 1993, Nancy DeStefanis, director of San Francisco Nature Education, discovered the first pair of nesting Great Blue Herons. This turned out to be the first recorded sighting of nesting Great Blue Herons in the city of San Francisco.
The herons court, build their nests, mate and lay eggs between January and March.
By April, at least one or more nests have chicks in them.
We start our interpretive program in April. The public can experience the excitement of these four foot tall birds with six foot wingspans flying in and out of the nests-brooding the chicks, feeding the chicks, etc.
Naturalists and interns from San Francisco Nature Education are stationed at the observation site with spotting scopes, ready to offer spectacular views into the Great Blue Heron nests and answer questions.
