About

This is a reference guide to fleshy, bird-dispersed fruits, especially identification of seeds. It will focus on fall- and summer-fruiting plant species found in southern Michigan, but since many of these species are widespread in North America, it will be useful for a broader region. Both native and non-native species are covered.

This website was a project of the former Rouge River Bird Observatory; part of RRBO's research was examining the fall diet of birds at an urban site. This page is now maintained by Julie Craves.
