The Hospital accepts both land and sea birds in need of care, to heal and return them to the wild. If this is not possible and they take kindly to captivity, then they are given sanctuary for the remainder of their lives. Those beyond help are painlessly destroyed.
During each year approximately 1000 birds are treated at the Hospital, and about 80 permanent residents. The Staff care for the birds 365 days a year in the same tradition as the founders.
The hospital was founded in 1928 by Dorothy and Phyllis Yglesias. Over the years the Sanctuary has become famous, especially so during the 1967 Torrey Canyon disaster, when over 8,000 oiled birds passed through the Hospital.
