Bird Feeder Experiment
We designed an experiment to see whether birds preferred different habitat and food types on the Pittsburg High School (PHS) campus. Everyone worked together to construct bird feeders, which we placed in three different local habitats (an open with no cover, an area with some bushes nearby, and an area near the trees by the school soccer field). Four feeders were placed in each habitat, and a different food type (wild bird seed, peanuts, thistle, or sunflower seed) was placed on each feeder. We observed the feeders for three weeks, recording the number and species of birds seen as well as weighing the amount of seed that was eaten at each feeder. Our results showed that PHS birds do show a slight preference for food and habitat types. We saw the most birds in the shrub and tree habitat areas. We think that this may be because of the protection that the trees and shrubs offer from predators. Birds ate all food types, but peanuts were the most popular food. Western Scrub Jays were the most common of the nine bird species seen.
