Title: Notes on the nesting of egrets near San Rafael, California

Author: Ralph, C. John; Ralph, Clement L.;

Date: 1958

Source: The Condor 60(1):70-71

Publication Series: Miscellaneous Publication

Description: On June 16, 1957, a trip was made by boat to Little Marin Island, off San Rafael, California, for the purpose of banding in the heronry that covers this small privately-owned island. We also wished to investigate the possibility of Snowy Egrets nesting there. The heron colony was conservatively estimated at 2000 birds, of which approximately 50 per cent were Common Egrets (Casmerodius albus), 20 per cent Snowy Egrets (Leucophoyx thula), and 30 per cent Black-crowned Night Herons (Nycticorax nycticorux) .
