This experiment was designed to test for food color preferences in black-capped chickadees (Parus atricapillus) and other local wintering birds. Color was offered as the only independent variable; suet was chosen as the test medium. Three colors were presented: red, green and natural (creamy white). Based on previous research, it was hypothesized that wintering birds would show a preference for red-colored suet over natural or green-colored suet. The results revealed a preference for natural (74% of the contacts) over red (18%) or green (8%). Two possible explanations are discussed: (a) The particular birds observed might not have been naive subjects, and (b) the species observed might not be sensitive to red.
