Birds are and important part of the world we live in. The eat pests, disperse seeds, pollinate plants, feed us, and provide us with recreational activities such as bird-watching and hunting. Park interpretive programs often feature birds because of the enjoyment they provide. Birds are also great indicators of change due to their high metabolism and position in the food web. Bird communities can serve as the "canary in the coal mine" so to speak for ecosystems. Unfortunately many birds, such as the Northern Bobwhite are declining in numbers for many reasons, such as habitat loss.

Scientists measure changes in bird abundance and habitat to determine the health of bird communities. They survey birds in the park during breeding season. They also survey habitat structure and composition. Together, the data helps researchers to determine responses of birds to their habitat. Regional surveys are also studied to determine local vs. regional trends.

Scientists have recorded 86 bird species in the park over the last 9 years. Seventy-four of which are breeding species found in the park. The Bell’s Vireo and Red-headed Woodpecker are considered species of concern for the region. The American Goldfinch, Dickcissel, House Wren, and Red-winged Blackbird were the most common species found in the park. Comparing regional and local trends it seems that the park habitat is similar to the habitat found region wide. Regionally, American Robin and Red-bellied Woodpecker populations are increasing. Whereas, Northern Bobwhite, Ring-necked Pheasant, and Red-winged Blackbird populations are declining.
Bird population changes may reflect management activities, such as restoring and maintaining specific habitats. For that reason scientists track changes in bird populations over time. Thus improving our understanding of birds and their specific habitat needs. Preserving habitat for birds preserves entire ecosystems for the benefit of all species.
