"We gardeners should be careful not to come between native birds and their partners, native plants. We've planted a number of nonnative species that are invading and degrading the wild habitats upon which birds depend. For example, Japanese honeysuckle (Lonicera japonica) has aggressively formed monocultures across the US, and although birds readily consume its fruits, it is replacing once-diverse native food sources, including dogwoods and viburnums, limiting the nutritious variety of foods that were historically available throughout the year." — Janet Marinelli, The Wildlife Gardener's Guide
