EXAMINING THE LOS ANGELES ZOO’S GARDENS FOR BIRD ACTIVITY

There are three garden types at the Los Angeles Zoo: 1) bird gardens (created for increasing bird habitat), 2) pollinator gardens (created for local pollinator species) and 3) general gardens (created for purposes other than wildlife habitat). In this study, we sought to determine which garden type is most successful in attracting birds, and what factors contributed to their success. The factors that we considered were the size of the garden, canopy, foot and car traffic, and proximity to natural habitat. We conducted five bird point-counts at eight sites throughout the Zoo and recorded observations of each individual. We ran ANOVA and correlation (Student’s t and Wald) tests. Despite the pollinator gardens’ implementation for Association of Zoos and Aquariums’ Saving Animals From Extinction, North American Songbird program, we found that the general gardens had the most (ANOVA, P=0.0002) bird visits and highest species richness. We believe that this is because these gardens were large areas close in proximity to natural habitat with a variety of flora and plenty of canopy cover. For future restoration efforts, we suggest implementing more canopy and native flora around the perimeter will best benefit native bird populations.
