Notes:
Grows as a vine, not a shrub. There are a number of native vining honeysuckles in Michigan:

Lonicera caprifolium (Italian Woodbine). Only found in one Upper Peninsula county.
Lonicera dioica (Limber Honeysuckle). Seeds are very similar to the non-native bush honeysuckles and may not be distinguishable.
Lonicera hirstuta (Hairy Honeysuckle). Found mostly in northern Michigan.
Lonicera sempervirens (Trumpet Honeysuckle).
Lonicera reticulata (Grape Honeysuckle). Only found in two Upper Peninsula counties.

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.
