High Rise Neighborhod
A Community in the Trees
Homes above your head are filling fast. Each January or February, Great

haven in this park. The eucalyptus trees serve as a popular apratment complex.
Once a year, these normally solitary birds come together as a heron colony to
raise their families.

Once the nest is ready, the parents incubate three to five light blue eggs for about
a month, taking turns being the stay-at-home parent. Shortly after the eggs

it will be at least two and a half months before they are ready to fly from the nest.
Herons are back from the edge of
extinction. The colony above you is
a success story. The San Francisco
Bay Birds Observatory's scientific
research and education programs
ensure more success stories like
this one in your community.
