Christine Tischer, Senior Biologist, has been managing the San Joaquin Wildlife Sanctuary’s tree swallow nestbox program since 1999. Although tree swallows are not a special-status species, they are a migratory bird species protected by the  Migratory Bird Treaty Act of 1918. The breeding bird survey found that this species was down to less than a handful of breeding pa irs in Orange County during the late 1980s and early 1990s. Tree swallows and western bluebirds were on the decline due to the shortage of natural cavities and competition for nest sites by non-native European starlings and house sparrows. A handful of nestboxes were installed by the Irvine Ranch Water District, with assistance from Sea and Sage Audubon, in the late 1990s.
Beginning with just eight volunteers, Christine oversaw the weekly scheduling of volunteers (including herself) ,  determined monitoring protocol, managed the data that were collected, defended the boxes from parasites and predators, and  readied the boxes for subsequent nestings once the chicks fledged. She took the initiative to contact a Master Bander and learned how to band tree swallows and eventually earned her in dividual banding permit.
Eighteen years later, Christine is still managing the program which has grown to 105 boxes and a group of 20 vol unteers and is now a registered site with Cornell University’s Golondrinas de las Americas international program. Christine is proud to be a part of this citizen science program that has successfully brought back the tree swallow as an Orange County breeding bird species.
