Perfect Paragraph 4/18

We will be comparing dietary style of bird species in relation to habitat type, and the effects these different habitats have upon beak shape and size. We will use the University of Massachusetts Amherst avian collection to collect data on bill length, depth, and width from preserved bird skins. We will use this collection because it will allow us to compare beak measurements of different species using a primary source of data. We will also use reliable ornithology research articles to find information on habitat types, behavior, and diet that will be used to compare bird species. The goal of this study is to analyze differences between beak size and shape, habitat and how they obtain their food. We aim to explore the proximate cause of distinct beak morphology of species by investigating the effects that different environmental pressures and/or dietary constraints have on the beak shape of birds. We seek to determine whether cohabiting species local to New England, as represented by specimens available from the UMass Amherst Ornithology collection, display trends of beak size and shape variation according to distinct dietary needs according to habitat, and analyze what that may mean in regards to how those species interact with one another and their shared ecosystem.
