cases of nest removal and disturbance. Nesting

on problematic structures is easily solved by the

installation of alternative artificial nest

structures. This has been accomplished for about

ten nesting pairs so far. Continued education of

wildlife agencies, biology consulting firms and

property managers about this approach will allow

this iconic species to continue to expand and

thrive in San Francisco Bay.
