Egret/heron rookery at the Port of Redwood City

In June 2012 an egret and heron breeding colony was discovered at the Seaport Center and Port property in the tall trees mostly along Chesapeake Drive, with the largest concentration at the intersection of Saginaw Drive and Chesapeake Drive.

August 2, 2014: Last survey report from San Francisco Bay Bird Observatory:

Unofficial numbers/trends:

  • Snowy Egrets – 16 nests, 30 adults, 19 young
  • Great Egrets – 4 nests, 7 adults, 7 young
  • Black-crowned Night Herons – 23 nests, 22 adults, 19 young

These are the same numbers that were reported in late June so the colony seems to be holding pretty steady.

SFBBO will soon be analyzing the data from the entire Colonial Waterbird Program and compiling a final report. Thanks to SAS members who assisted in our efforts to inform the public about the importance of protecting this valuable natural asset.
