Fruit size, seed load, and seed size are considered important metrics influencing fruit choice and subsequent seed dispersal by birds. I describe these traits for 37 plant taxa in southeast Michigan, based on measurements of over 5,800 fruits and 8,000 seeds. I also provide nearly 200 measurements for the same taxa found in the literature. These data can be used in biogeographical studies and aid conservation and restoration efforts by describing traits preferred by birds which in turn influence seed dispersal throughout landscapes.
