Living with Aliens: Effects of Invasive Shrub Honeysuckles on Avian Nesting
Figure 1
Honeysuckle species (Lonicera maackii and L. morrowii) were the dominant vegetation cover around the nests and was also the most used nesting substrate.
Panel A shows the average cover of each plant species within a 2 m radius around nests found in the study sites. Morrow's honeysuckle (L. morrowii) was the dominant species found in the vegetation cover analysis. Panel B shows the number of nests built in each substrate (i.e., plant species). More nests were built in honeysuckle species than any other shrub used for nesting substrate. The inset shows the average number of nests found in each substrate category (i.e., honeysuckle spp., and all other plant species). We found significantly more nests built in honeysuckle species than in all the other species given the availability of each substrate category. (*P≤0.05).
